chromaS application: emission monitoring in a paper mill

The paper industry uses large quantities of sulphur substances particularly during the process of cellulose cooking (Kraft burning).

The release of these substances in the air is an issue for the environment in terms of odors and toxicity. These factories have to be equipped with gas cleaning systems to limit their emissions.

Chromatotec recently installed two chromaS analyzers to validate and follow up the operation of bioactive cleaning systems ; a CHROMA S analyzer was installed upstream of the cleaning system and another one downstream to monitor the concentrations of COS and H₂S between 0 and 1000 mg / m3.

New application on heavy compounds is presently developped (certified cylinder) and a comparison is made between chromaS and MEDOR.
