FTIR for CEM’s and VOC’s monitoring

As major contributors to environmental emissions, the waste incineration and power generation industries require both continuous and periodic emissions monitoring to ensure each plant is within Emission Limit Values (ELVs). FTIR provide to perform emissions monitoring solutions for the range of standard incineration or “combustion” gases, both inorganic species such as CO, NOx, SO2, CO2, acid gases such as HCl, NH3, HF and organic emissions measurement.

BS EN 14181 is a quality assurance standard relevant to plants operating under the Large Combustion Plant (LCPD) and Waste Incineration (WID) Directives. Quality Assurance Level 2 (QAL2) of this standard involves the parallel testing of the plant automated measurement systems (AMS) against a certified test house, making measurements with a comparative standard.

Total Volatile Organic Compounds (VOCs) is a common measurement required from industrial emissions. Commonly, a single measurement value is obtained through the use of a Flame Ionisation Detection (FID) analyser. The pyrolysis of the gas stream in a FID analyser allows it to make a measurement of the carbon content of the gas stream. FID analyser cannot indicate the relative abundances of different organic species in a gas stream and often have widely different responses for different gases. However, they are taken as the standard reference method for Total VOC emission measurements.
