- Sulphur compounds analysis: natural gas odorisation or chemical industry

Abstract ANALYSE INDUSTRIELLE 2008 - Paris, France
Smells are connected to the presence of sulphur, nitrogenous or Volatile organic compounds.

The sulphur compounds are present in the industrial environment and generate smells to be treated. They also represent an important risk of toxicity.

The analysis of these compounds is essential in the field of natural gas: In that case the gas is ”odorized” by injecting a quantity of tetrahydrothiophene (THT) for example.

In case of leak this "odorization" allows a better follow-up of gas and thus to take the maximum of precautions for civil security.

Implanted directly in the counting stations of the natural gas network, Energy MEDOR enables the control and the specific dosage of H2S, Mercaptans and THT during a standard cycle of 20 min.

During the cellulose cooking in a paper mill the releases of toxic compounds lead the manufacturers to equip their factory with “gas cleaning” systems.

The efficiency of cleaning upstream and downstream is monitored by an analysis of compounds COS and H2S.
The analyzer Chroma S has a detector FPD and allows the continuous analysis of following compounds: H2S, R-SH, sulphur and COS, CS2, SO2.
