Emission monitoring

Boilers, furnaces, and incinerators are key utilities in every chemical plant and have a big impact on the environment. The quantity and nature of emitted components are regulat-ed by local authorities via emission standards and limits. Therefore, O2, NOx, CO, SO2, NH3, CH4, HCl, HF, and others are often required to be monitored on a continuous basis. However, the analytical solutions depend on the fuel type and the combustion process. As a global market leader for emission monitoring systems, SICK offers a broad variety of in-situ, cold/dry, and hot/wet extractive solutions.
