			<content:encoded><![CDATA[<p>NASA scientists have concluded that at least one of the large lakes observed on Saturn&#8217;s moon Titan contains liquid hydrocarbons, and have positively identified the presence of ethane.  This makes Titan the only body in our solar system beyond Earth known to have liquid on its surface. Scientists made the discovery using data from an instrument aboard the Cassini spacecraft.  The instrument identified chemically different materials based on the way they absorb and reflect infrared light.  Before Cassini, scientists thought Titan would have global oceans of methane, ethane and other light hydrocarbons.  More than 40 close flybys of Titan by Cassini show no such global oceans exist, but hundreds of dark, lake-like features are present.  Until now, it was not known whether these features were liquid or simply dark, solid material. &#8220;This is the first observation that really pins down that Titan has a surface lake filled with liquid,&#8221; said Bob Brown of the University of Arizona, Tucson.  Brown is the team leader of Cassini&#8217;s visual and mapping instrument.  The results will be published in the July 31 issue of the journal Nature. Ethane and several other simple hydrocarbons have been identified in Titan&#8217;s atmosphere, which consists of 95 percent nitrogen, with methane making up the other five percent.  Ethane and other hydrocarbons are products from atmospheric chemistry caused by the breakdown of methane by sunlight. Some of the hydrocarbons react further and form fine aerosol particles.  All of these things in Titan&#8217;s atmosphere make detecting and identifying materials on the surface difficult, because these particles form a ubiquitous hydrocarbon haze that hinders the view.  Liquid ethane was identified using a technique that removed the interference from the atmospheric hydrocarbons. The visual and mapping instrument observed a lake, Ontario Lacus, in Titan&#8217;s south polar region during a close Cassini flyby in December 2007.  The lake is roughly 20,000 square kilometers (7,800 square miles) in area, slightly larger than North America&#8217;s Lake Ontario. &#8220;Detection of liquid ethane confirms a long-held idea that lakes and seas filled with methane and ethane exist on Titan,&#8221; said Larry Soderblom, a Cassini interdisciplinary scientist with the U. S.  Geological Survey in Flagstaff, Ariz.  &#8220;The fact we could detect the ethane spectral signatures of the lake even when it was so dimly illuminated, and at a slanted viewing path through Titan&#8217;s atmosphere, raises expectations for exciting future lake discoveries by our instrument. &#8220;The ethane is in a liquid solution with methane, other hydrocarbons and nitrogen.  At Titan&#8217;s surface temperatures, approximately 300 degrees Fahrenheit below zero, these substances can exist as both liquid and gas.  Titan shows overwhelming evidence of evaporation, rain, and fluid-carved channels draining into what, in this case, is a liquid hydrocarbon lake. Earth has a hydrological cycle based on water and Titan has a cycle based on methane.  Scientists ruled out the presence of water ice, ammonia, ammonia hydrate and carbon dioxide in Ontario Lacus.  The observations also suggest the lake is evaporating.  It is ringed by a dark beach, where the black lake merges with the bright shoreline.  Cassini also observed a shelf and beach being exposed as the lake evaporates.  &#8220;During the next few years, the vast array of lakes and seas on Titan&#8217;s north pole mapped with Cassini&#8217;s radar instrument will emerge from polar darkness into sunlight, giving the infrared instrument rich opportunities to watch for seasonal changes of Titan&#8217;s lakes,&#8221; Soderblom said. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency.  The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA&#8217;s Science Mission Directorate, Washington.  The Cassini orbiter was designed, developed and assembled at JPL.  The Visual and Infrared Mapping Spectrometer team is based at the University of Arizona.  </p>

			<content:encoded><![CDATA[<p>Using organic fertilizers is a widely accepted practice in the agricultural industry.  Farmers use them to cultivate their field and row crops, winemakers utilize them for growing grapes, and horticulturists apply a liberal does of these during the landscaping of their orchards or turfs.<br />
Liquid organic fertilizers are a safe and effective way of providing your plants with the best nutrient supply without harming them or increasing the soil&#8217;s acid content.  Liquid organic fertilizers act as agents to effectively increase the content levels of nitrogen, phosphate, and potassium.  Because these three substances are the three major nutrients that plants need, liquid organic fertilizers thus provide plants with an abundant food supply essential for their growth.<br />
Liquid organic fertilizers are especially important in helping the plants overcome the tension involved in transplanting, cold weather, or dry season.  Because liquid organic fertilizers help enrich the soil, they assist in removing the risk of soil nutrient-deficiency.<br />
There are two basic methods of application for liquid organic fertilizers &#8211; through spraying or through direct application to the soil around the plant.  Spraying is the more commonly used method of applying liquid organic fertilizers.  This is because plants usually take in nutrients through their leaves and stems where their stomata are located.  Liquid organic fertilizers sprayed on plant leaves and stem allow them to absorb the nutrients faster.<br />
The other method used for applying liquid organic fertilizers are called direct or tea application.  Liquid organic fertilizer direct application is like adding tea to the soil around the plant.  Liquid organic fertilizer direct application still has the same nutritional component as the spray type.  The only difference is that with the liquid organic fertilizer direct application method, nutrients such as nitrogen and potash may be wasted because they are not easily absorbed by the plants.<br />
There are several types of liquid organic fertilizers available in the market.  The most common liquid organic fertilizer is fish emulsion.  Made from ground up and liquefied fish parts, fish emulsion liquid organic fertilizer contains trace elements essential for plant growth.  Fish emulsion liquid organic fertilizer also has high content level of nitrogen, the nitrate source for plants.  Fish emulsion liquid organic fertilizer may be sprayed on the plant&#8217;s foliage or applied directly as tea.<br />
Liquid organic fertilizers can also be made from earthworm castings.  Earthworms play a major role in providing the soil with minerals and vitamins that help plants grow and this is what led scientists to manufacture earthworm-based liquid organic fertilizer.<br />
Another type of liquid organic fertilizer is the bat guano.  Several more manufacturers have produced liquid organic fertilizers containing any combination of the following: fish meal, soybean protein extract, rock phosphate, bone ash, potassium carbonate, magnesium carbonate, sea kelp, and humic acid. </p>

			<content:encoded><![CDATA[<p>As technology improved, so did the nitrogen generator systems, and recent discoveries have led to the reducing of the nitrogen generators size. &#13;<br />
&#13;<br />
These new-generation, small size nitrogen generators are very effective and reliable, and they operate automatically, with very little maintenance required. &#13;<br />
The main difference between these nitrogen generators and the normal ones is the size, these small capacity units only take up 60% of the space used by a usual nitrogen generator, saving 40%. &#13;<br />
Another difference is that these nitrogen generators do not supply a 99. 99. . % pure nitrogen, but something around 95% pure, which is not a disadvantage because most users and laboratories don&#8217;t require 99. 99. . % pure nitrogen.  The nitrogen&#8217;s purity may be increased to 99. 5% if the user desires to do so, by absorbtion or, cheaper, by adding a process to the nitrogen generator, that runs the resulting gas through a special filter that reduces the oxygen concentreation from the resulting gas.  Also, if the buyer requests, he will also receive vaporization systems and liquid nitrogen storage together with the nitrogen generator. &#13;<br />
&#13;<br />
These units have been tested, and they have been found to meet al the requirements of a nitrogen generator, and they are the best and cheapest solution to many needs. &#13;<br />
&#13;<br />
The pressure of the gas delivered by the small-size nitrogen generators can vary around 6-7 Bar(g), and it can be increased with the help of a compressor. &#13;<br />
&#13;<br />
In conclusion, these nitrogen generators are the best solution if you wish to save space &amp; money, and not only, they can be used by everybody because they require little maintenance, low power, they have a compact design and they can operate unattended and monitor themselves. &#13;<br />
&#13;<br />
So as a final conclusion compact nitrogen generators are available for purchasing to everyone on the internet maket. &#13;</p>

			<content:encoded><![CDATA[<p>Some of the new-generation nitrogen generators use the APSA process to generate nitrogen.  This APSA process relies on the fractionated distillation of air at very low (cryogenic) temperatures, and in only one column.  In other words, APSA nitrogen generators are nitrogen generators that use cryogenic distillation of air to generate nitrogen. &#13;<br />
&#13;<br />
After the air is being compressed, it is purified in the nitrogen generator, so that the cryogenic operation runs smoothly.  The air is being compressed at around 9 bars with a centrifugal or a screw compressor and afterwards cooled down with the help of a cooling unit. &#13;<br />
&#13;<br />
The air that runs through the nitrogen generator must then be purified, so it passes through several filters and cooled down some more. &#13;<br />
&#13;<br />
Afterwards the criogenic process must intervene, so the air enters a special area of the nitrogen generator, the cooling area, and then the oxygen in the air is separated from the nitrogen.  At the bottom of the area there will be a liquid that is oxygen-rich and at the top the desired nitrogen. &#13;<br />
The low temperature inside the nitrogen generator is mantained using a small quantity of liquid nitrogen, which is then added at the produced nitrogen. &#13;<br />
&#13;<br />
This process is designed so that it&#8217;s all automatically controlled, it requires no manual procedures.  If problems occur, the nitrogen generator is created so that it will try to solve them on its own. &#13;<br />
For example, if the nitrogen consumption increases, a pressure regulator will maintain the normal pressure.  Or, if the concentration of oxygen is too high, the APSA process is automatically closed and the excess of oxygen is ventilated outside.  Furthermore, the nitrogen generator waits for the oxygen levels to decrease, and if they don&#8217;t, the whole system is shut down.  When this occurs, the nitrogen generator takes safety precautions. &#13;</p>

			<content:encoded><![CDATA[<p>All I need is the air that I breathe?.  Like most living organisms, humans have a few basic requirements for sustaining life ? and sadly beer and curry are actually not on that list! Oxygen is essential for life and our requirements are actually quite specific and relate to the atmosphere that we as a species have developed in.  Any depletion of the oxygen level in air must be treated with concern, and as a minimum the concentration in the workplace should be maintained above 19. 5%.  Crucially, atmospheres containing less than 18% oxygen are potentially dangerous and suitable protection methods should be adopted (e. g.  the use of breathing apparatus).  Asphyxiation as a result of oxygen depletion can take place on a gradual or sudden basis, depending upon the extent of the depletion.  It is a little known fact that inhalation of a gas containing virtually no oxygen can result in immediate unconsciousness and rapid death.  The symptoms associated with oxygen depleted atmospheres are detailed in Table 1.  Table 1 &#8211; Asphyxia Symptoms for Low Oxygen Levels % Oxygen Content of Air &amp; Signs and Symptoms of Asphyxia 18% &#8211; 19. 5% &#8211; May affect physical and intellectual performance without person?s knowledge.  15% &#8211; 18% &#8211; Decreased ability to work strenuously.  May impair co-ordination and may induce symptoms in persons with coronary, pulmonary, or circulatory problems.  12% &#8211; 15% &#8211; Respiration deeper, increased pulse rate, and impaired co-ordination, perception and judgment.  10% &#8211; 12% &#8211; Further increase in rate and depth of respiration, further increase in pulse rate, performance failure, giddiness, poor judgment, blue lips.  8% &#8211; 10% &#8211; Mental failure, nausea, vomiting, fainting, ashen face, blue lips.  6% &#8211; 8% &#8211; Loss of consciousness within a few minutes, resuscitation possible if carried out immediately.  0% &#8211; 6% &#8211; Loss of consciousness almost immediate, death ensues, brain damage even if rescued.  Liquid nitrogen ? the great cryogen Liquid nitrogen (LIN) is used in extensively across the World, particularly for its excellent cryogenic properties.  Produced from the liquefaction of air, it is colourless, odourless and exists at temperature of -196oC at atmospheric pressure.  Liquid nitrogen is the preferred method of cryogenic storage, for example in the preservation of biological samples, as unlike electrical freezers it relatively cheap to purchase, does not rely on electricity (and is not susceptible to electrical outages) and has low running costs.  It is supplied via specialised road tanker into insulated storage vessels, ranging from non-pressurised dewars and desks flasks to pressurised tanks for mobile or static storage.  Liquid nitrogen is also very safe under normal usage and many people associate the extreme cold temperature as the main source of risk.  However, when Liquid Nitrogen evaporates (e. g.  through spillage) it undergoes a large volume expansion as it returns to the gaseous form ? one litre of liquid nitrogen produces approximately 680 litres of nitrogen gas! This expansion ratio will quickly displace the atmosphere within a confined space and can cause oxygen depletion if control measures are not in place.  To find out more about Liquid Nitrogen, go to CryoService pages on: Liquid Nitrogen Providing early warning Whilst fully-integrated ?cryorooms? are discussed later, one of the most critical aspects of safety awareness and enhancement in these applications is the correct use of gas detection equipment, in the form of oxygen depletion monitoring A typical oxygen depletion monitor consists of an electrochemical sensor which generates a small electrical signal in proportion to the concentration of oxygen present.  This sensor signal is then amplified to display the oxygen level on either a portable or fixed-point instrument.  Oxygen sensors are typically calibrated in air (having first been zeroed using 100% nitrogen) so that 20. 9% volume oxygen is displayed in clean-air environments.  Oxygen depletion alarms are usually set at 19% and 17% volume.  Portable instruments are typically worn on breast pockets (ie within the vicinity of the breathing zone) to provide protection to personnel.  Staff working within an area where an oxygen depletion risk exists are trained to evacuate immediately in the event of their portable monitor producing a low oxygen alarm.  Fixed-point oxygen monitoring systems utilise one or more oxygen sensors installed in the vicinity of potential nitrogen leak sources (ie near vessels, flanges, valves etc), which are connected to a control panel.  The sensors permanently monitor the area, and the control panel displays the gas levels and provides alarms in the event of a sensor reporting a reduced concentration of oxygen.  Control panels can also be used to take executive actions such as closing solenoid valves to prevent further nitrogen releases.  Fixed systems provide the significant advantage of warning of a reduced level of oxygen before personnel enter an area.    To understand more about oxygen depletion system, visit the Crowcon gas detectors site at Crowcon. com Case Study ? ?Workers at one of the UK&#8217;s largest vacuum test chambers kept safe with Crowcon gas detectors? To protect workers from the danger of depleted oxygen levels, the Rutherford Appleton Laboratory has recently installed four Crowcon gas detectors and a Gasmaster control panel.  The Gasmaster control panel displays oxygen levels in all the testing cleanrooms simultaneously on a large, LCD display, allowing full system status checks at a glance.  The Crowcon units are installed in the Assembly Integration and Verification (AIV) Facility&#8217;s suite of cleanrooms, where spacecraft and satellite components are subjected to extreme temperature and vacuum conditions.  The facility has a number of vacuum chambers and other testing laboratories.  The largest vacuum chamber ? one of the biggest in the UK ? is highly versatile and can simulate near-space conditions with temperatures from -196oC to + 150 oC.  The chambers are returned to atmospheric pressure by introducing nitrogen gas.  It can take up to four hours to return the largest chamber to atmospheric pressure, and if nitrogen leaked out during this time, it could result in rapid oxygen depletion in the laboratory.  The oxygen sensors ensure that should this happen, the Gasmaster control panel will instantly inform controllers which detector has been activated with a visual signal such as &#8220;Vacuum chamber 1&#8243;, as well as activating audible/visual alarm devices.  &#8220;Our air conditioning system changes the air up to six times an hour so if there ever was a nitrogen leak, the aircon would normally take care of it,&#8221; commented technician Dave Rippington.  &#8220;The Crowcon systems are really in place as part of a &#8216;belt and braces&#8217; approach, ensuring our workers are safe in the highly unlikely event that there was both a nitrogen leak and the air-con system failed. &#8221; Best practise control measures The main application considered here is biological sample storage within typical research, academic and hospital environments and there are effectively two infrastructures in which this product is used.  The first is the purpose-designed ?cryoroom?, a dedicated facility for the storage of preserved samples and the supply of Liquid Nitrogen to them.  These have generally undergone extensive design and feature best practise in risk management.  Typical features of a dedicated cryoroom are:  External storage of Liquid Nitrogen.    A transfer pipeline for Liquid Nitrogen into the cryoroom ? this is often referred to as Super Insulated Vacuum Line (SIVL) as it is highly insulated to prevent Liquid Nitrogen boil-off.    The use of large cryogenic freezers, generally storing samples in vapour phase (reduces the amount of Liquid Nitrogen contained) with automated temperature control and auto-fill systems.  The latter means that personnel do not have to be present when the freezers are being filled; and systems can operate on a time or level basis.    An integrated fixed gas detection system, often with multiple sensors and alarms linked to a Business Management System and a safety shut off solenoid for the SIVL line to cut-off the Liquid Nitrogen supply in the event of an oxygen depletion alarm.    A ventilation system linked to the gas detection equipment, providing increased throughput on low oxygen levels.    A door interlock system that allows escape but prevent access in emergency conditions.    Specialised flooring and lifting equipment.    An extensive maintenance routine covering all aspects of the system.   The second type is where Liquid Nitrogen is used in individual laboratories from small wheeled tanks or from unpressurised dewars.  Liquid Nitrogen is generally manually decanted using a hose or transfer device into small aluminium freezers with liquid phase storage.  Whilst this arrangement is not as desirable as the purpose-built cryoroom, building infrastructure issues or funding often means that it is the most pragmatic way to operate.  Safety can be maximised in these situations by considering the following:  Minimise the storage of samples in a laboratory.  Many facilities retain samples for archiving purposes that will rarely if ever be used in daily operation.  Several private off-site repositories have opened in the UK specifically to assist with this problem.    Minimise the amount of Liquid Nitrogen stored in your laboratory.  Can the vessels be stored in a suitable outside area, where product can be transferred into a non-pressurised dewar for topping up freezers periodically?   The use of a phase separator (a small sintered device) on liquid nitrogen transfer hoses to minimise splashing and resultant evaporation.    The use of gas detection to allow early warning of oxygen depletion.  Consider the fitment of a ?repeater? or external alarm that is visible outside the laboratory to prevent people entering in emergency conditions.  Fixed monitors are preferable to personal monitors as they protect everyone in an area.    Ensuring adequate ventilation, through LEV or similar.  Remember that cold nitrogen gas is heavier than air and will accumulate in low areas such as pits or gulleys.

<p>A large chemical plant explosion near Seabrook early this morning sent a gigantic plume of smoke billowing into the air, but there were no serious injuries.</p>
<p>The explosion occurred at an American Acryl facility at 11600 Port Road near old Texas 146 about 8:50 a.m., according to the Seabrook Police Department. A short section of Texas 146 near the blast site was closed in both directions, as is Port Road.</p>
<p>An hour later, firefighters appeared to have the fire out, and no smoke was visible from the charred wreckage at the plant. Two people went to Memorial Hermann Hospital Southeast complaining of discomfort, said Seabrook police Lt. Sean Wright.</p>
<p>Memorial Hermann spokeswoman Jennifer Hart said both were in good condition.</p>
<p>Area residents were asked to shelter in place after the blast, but that recommendation was lifted by 11 a.m. Officials said the blast involved toluene, a toxic substance that can cause nausea and tiredness in low to moderate levels.</p>
<p>However, in a recorded message company said the explosion did not cause a release of the chemical.</p>
<p>Shoreacres Police Officer D. Cantu, who was in the La Porte area at the time, said he heard the blast and turned in time to see &#8220;a ball of fire going up into the air.&#8221; Reports indicate the blast was heard or felt as far away as Baytown and Pearland.</p>
<p>American Acryl was permitted in 2000 to build a $150 million chemical plant in the Bayport industrial district.</p>
<p>The facility is built on about 65 acres and and includes a 120,000-ton-per-year acrylic acid plant.</p>
<p>Acrylic acid is a key component in many commonly used household and personal care products such as disposable diapers and water-based products for paints, inks and adhesives.</p>
<p>American Acryl was formed in 1997 and is a 50-50 joint venture between NA Industries Inc. and Atofina Chemicals Inc., who are the North American subsidiaries of Nippon Shokubai and Total Fina Elf S.A., respectively.</p>

			<content:encoded><![CDATA[<p>It&#8217;s not just you and your eco-conscious neighbors who are looking for ways to conserve energy and preserve the environment. The term &#8220;carbon footprint&#8221; is the new catchword of the day, and businesses are learning that it applies to their own big &#8220;shoe&#8221; as well.</p>
<p>Saving energy makes sense all around. Businesses that put energy conservation measures in place help preserve the environment, make use of renewable resources, AND save money.</p>
<p>There are plenty of simple ways that businesses can encourage energy conservation, recycling, and environmental awareness, both on an individual and corporate level.</p>
<p>For instance, research shows that recycling an aluminum can save 95 percent of the energy required to make the same amount of aluminum from virgin materials. Producing glass from virgin materials requires 30 percent more energy than producing it from crushed, used glass; recycled paper requires about 60 percent of the energy used to make paper from virgin wood pulp.</p>
<p>If your company has an application or production need for Nitrogen, PSA and Membrane Nitrogen Gas Generators cut down on energy use considerably by completely eliminating the necessity of converting nitrogen into liquid form for transportation and delivery. Making liquid Nitrogen requires that Nitrogen gas be pressurized and cooled to very low temperatures, a process that involves a large amount of energy.</p>
<p>Nitrogen generators cut out that process entirely, since all you need is a source of compressed air &#8211; an infinitely renewable resource &#8211; to make Nitrogen gas. As the air is fed into the generator, oxygen and other molecules are trapped, then vented out while the Nitrogen is pushed into a storage tank.</p>
<p>Nitrogen Gas Generators are a simpler, &#8220;greener&#8221;, and far more cost-effective way to meet your Nitrogen needs.</p>
<p>A Nitrogen Generator &#8220;borrows&#8221; Nitrogen from the air for your application. It then goes right back out to the air where it belongs, without dragging along dirt or contaminants with it, or creating any other particulate or nasty substance to alter the world around us. Nitrogen Generators also cut down on huge tankers hauling liquid down our nation&#8217;s highways. Plus, Nitrogen comprises more than 78% of the air, so it is an infinitely renewable resource.</p>
<p>And what will you do with the money you save when you end your gas contract and make your own Nitrogen with a Nitrogen Generator? You might look into even more opportunities to be greener with your business. Corporate tax incentives for energy efficient lighting, building insulation, renewable energy resources and many more energy and cost saving technologies have been in place for several years, and some have been extended this year. Considering some &#8220;green&#8221; modifications with the money you no longer pay the gas company might make those savings go even farther with energy conscious tax breaks.</p>
<p>Investing in a Nitrogen Generator will result in a positive return on investment for both your business and the world around you. Consider making this change today.</p>

			<content:encoded><![CDATA[<p>Liquefied natural gas, often abbreviated LNG, is simply the liquid form of the natural gas commonly used for heating homes, cooking, and fueling electrical power plants, among other uses. As you may know, natural gas is a fossil fuel that occurs naturally deep within the earth, most often accompanying deposits of oil but sometimes occurring alone. Liquefied natural gas is formed through the process of liquefaction, in which heat is removed from the natural gas and it is converted to a lightweight liquid. </p>
<p>&#13;</p>
<p>Natural gas is primarily composed of methane, though traces of other elements and compounds, including water, may also be found within it. Some substances, such as water, must be removed before liquefaction because the extremely low temperature required for the process causes certain such substances to form solids. Liquefied natural gas is colorless, odorless, and produces low emissions when burned as compared to other fossil fuels. </p>
<p>&#13;</p>
<p>Converting natural gas into liquefied natural gas allows for efficient transportation and storage of the resource. When natural gas is converted to LNG, its volume is significantly decreased, facilitating efficient transport by water over the long distances between continents, thus allowing for the cost efficient import and export of this valuable resource. When a specifically designed LNG carrying ocean vessel delivers its cargo to one of the import terminals in the United States, the liquefied natural gas is stored in special storage tanks until it is time for it to be converted back to a gas and delivered via pipeline to natural gas consumers. Companies providing electric power and natural gas may also ?stock up? on LNG when prices are low for use during peak demand times, a technique known as peak shaving.</p>
<p>&#13;</p>
<p>The demand for natural gas in the United States is widely believed to be increasing at a higher rate than supply at the current level can fulfill. The industry is complex in that numerous levels of the supply chain must align in order to be economical. The vessels that transport liquefied natural gas, import stations where such vessels deliver the gas and the facilities which perform the process of liquefaction as well as converting the liquid back to a gas are extremely specialized and must strike a balance in order to ensure that the process is economical and efficient. Locating and extracting natural gas from within the earth, converting it into a liquid state, safely transporting it via pipeline and or ocean vessels, and converting it back into its gaseous state in an economical way is important to maintaining manageable prices for consumers. </p>
