Advances in gas control technology in the brewery
The use of nitrogen as a process gas, foam enhancer and flavour modifier has come to the fore over the last 10 years, with dissolved gas specifications becoming more stringent. Increasingly, marketing and consumer requirements for a targeted product identity or image have to be met, not only for taste but, perhaps equally as importantly for the consumer, presentation. This has resulted in ...

Biomedical research looks to thermal mass flow controllers
Precision control in biomedical research is critical for the success of any experiment. This is especially true for gas mixing and blending applications. These gas mixing applications often involve the creation of artificial atmospheres or other gas mixtures. To get statistically sound results, scientists must achieve precision flow control in creating these mixtures for sensitive experiments. In ...

Greenhouse Gas Emissions Control
Most of the time, people think about Greenhouse Gas (GHG) emissions with carbon dioxide, which is the most common of the GHGs. While fairly typical, carbon dioxide isn’t the only GHG U.S. Environmental Protection Agency (EPA) regulates. Since EPA has begun regulating GHG emissions under its Clean Air Act authority, sources of emissions from others may require add-on air pollution control ...

Mass Flow Control in Bioreactors - Case study
Vogtlin mass flow controllers are an excellent tool for precise control of gas flows in bioreactors. Bio reactors are used for critical and delicate processes where mass flow control of relevant gases need to be reliable, repeatable and flexible. For example, the dissolved oxygen needs to be carefully controlled to obtain repeatable pH control and volumes of fermentation gases like CO and H2 ...

Utilisation of Municipal Solid Waste Compost as landfill cover soil for reducing greenhouse gas emission
Municipal Solid Waste Compost (MSW-C) was introduced for improving landfill cover soil properties and enhancing methane oxidation. The landfill cover soil was irrigated with leachate for maintaining appropriate moisture content for methane oxidation reaction. It was found that MSW-C was an effective landfill cover material for landfill gas emission control exhibiting the highest Methane Oxidation ...

How to analyze H2S, all Mercaptans, THT as well as total sulfur for monitoring natural gas or gaseous fuels in metering station?
Natural gas is colourless and odourless in its most pure form. When extracted, it can contain sulfur compounds such as H2S and Mercaptans that when in the presence of moisture can produce sulfuric acid that can degrade the pipeline. So for reasons of public safety as well as pipeline integrity, there is a need to measure and control precisely the level of odorant species in natural gas : ...

Nonthermal Plasma Applications to the Environment: Gaseous Electronics and Power Conditioning
Abstract—For nearly two decades, interest in gas-phase pollution control has greatly increased, arising from a greater respect for the environment, more attention to the effects of pollution, and a larger body of regulations and laws. Nonthermal plasma (NTP) technology shows promise for destroying pollutants in gas streams and cleaning contaminated surfaces, using plasma-generated reactive ...

Repeatability is King: Up to Tenfold Improvement
Axetris has improved the repeatability specifications of its mass flow meters and controllers. Repeatability often more important than absolute accuracy Repeatability provides information about the precision, that is, the absolute difference between a pair of repeated test results measured by one instrument under unchanged conditions. To measure precision, the same procedures are used under the ...
