Testing linearity of Air quality analyzers

by Be.T.A. Strumentazione Srl     based in Borgolavezzaro, ITALY

To test gas analyzers for Air Quality monitoring, gas references must have concentration in the range of hundreds to tenths ppb. Test gas bottles with so small concentrations are expensive and unstable. With the gas divider BetaCAP30X100 it's possible to dilute high concentration test gases getting 30 dilution steps in the range from 1:100 to 1:3.000 of the original test gas bottle concentration. Traditionally MFC based diluters are used for this application, but now our capillaries based diluter is available, with more stable performances.

Waste water treatment plants Air quality control by TRS MEDOR

by Chromatotec Group     based in Val de Virvée, FRANCE

Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. At the entrance of the waste water plants, where the waste water arrives, strongly smelling and polluted air is captured and neutralised by a chemical cleaning process called ‘’Stripping’’. The correct amount of chemical products needed to neutralise the polluted air has to be calculated.

CH4 Monitoring in Air

by Unisearch Associates Inc.     based in Concord, ONTARIO (CANADA)

CH4 (Methane) is a colorless, odorless natural gas that is used in a wide variety of industrial applications such as power generation and chemical production. It is also a byproduct of many biological and geological processes, fracking, and gas drilling. It is highly flammable and creates amounts of carbon monoxide as its combustion byproduct. Methane needs constant monitoring in waste water treatment (for co-generation) and to ensure proper process control (e.g. to determine burning efficiency). A quality CH4 analyzer that is able to provide continuous monitoring is a perfect solution for this.

Gas monitoring instruments and systems for stack testing

by Gasmet Technologies Oy     based in Helsinki, FINLAND

Several EU directives and national laws in European countries set requirements for continuous monitoring of flue gas emissions at power plants. Further requirements are set on the quality assurance of the installed measurement systems at the plants. The relevant standard in this regard is EN 14181:2004, the quality assurance of automated measuring systems. The standard dictates how to determine that the measurement systems installed for continuous emissions monitoring at a plant operate according to the directives and regulations set. Two major parts of this on-going quality assurance cycle are the QAL2 and AST procedures. A test laboratory performs tests on the systems on-site, and determines whether the systems fulfill the set requirements or not.
