  • Choosing flow monitors for CEMS applications

    As a result of the 1990 Clean Air Act Amendments1, electric power plants must reduce their emissions of sulfur dioxide and nitrous oxides—the primary causes of acid rain. The U.S. Environmental Protection Agency (EPA), in its proposed rules2, designates the 111 Phase I fossil-fueled plants ^roughly 268 boiler units) that must have continuous emissions monitoring systems (CEMS) installed, ...

  • Beyond Karl Fischer: Titration Methods

    Almost every industry is concerned about water concentration levels in some way. Food and pharmaceuticals automatically come to mind, but fuel, explosives, agri-chem, and polymer processing businesses (to name a few) all rely on moisture content as a critical quality attribute. Karl Fischer titration (KFT) is the best-known technique for determining water levels in samples, and it is supported ...

  • Moscow snow reveals new air pollutants

    GC-MS analysis of Moscow snow reveals new pollutants in the city air. Cities, with their traffic, industrial centers and factories, usually suffer from some degree of air pollution. Moscow, which houses all of these as well as power plants and an oil refinery, is no different. Regular monitoring of environmental pollutants is common practice in many cities and priority pollutants are detected and ...

  • Monitoring of Hydrogen Sulfide in Industrial Processes

    Hydrogen sulfide, H2S, is a very poisonous, corrosive, and flammable gas. As such, it needs to be carefully monitored and controlled in industrial processes where it is generated or used. At relatively low concentrations, it has an odour of rotten eggs which effectively works as a warning, but at higher concentrations where it becomes acutely toxic and even lethal, it can no longer be smelled ...

  • The effect of draw out lens diameter on sensitivity of GC–MS analysis

    Gas chromatography–mass spectrometry (GC–MS) allows isolation and identification of individual analytes within a complex mixture. Helium has traditionally been the first-choice carrier gas, owing to its inertness, performance, and relatively cheap price. Since 2001, however, helium has become increasingly expensive with a reported global increase in price of 500% between 2001 and 2016 ...

  • Continuous Emission Monitoring Ensuring Cleaner Air and Better Safety

    Emission monitoring refers to the on-going processes of collecting the data on the gases and components released in the air by industrial plants. In this article we will discuss the ABC of emission monitoring at a general level: What is emission monitoring? What needs to be taken into consideration when planning a well-oiled measuring ...
