Hydrogen sulfide (H2S) represents a very common pollutant encountered in natural gas, oil and gas applications. Undesirable because of its human and environmental toxicity, corrosiveness and unpleasant smell, various methods have been developed to eliminate this contaminant.
For decades, an effective and economical method is employed using MEA-triazine as a scavenger for the H2S, resulting in the formation of the kinetic by-product, called dithiazine. Although the formation of dithiazine is a good indicator of the elimination of the H2S, its poor solubility represents a real issue during the process, leading to reduced permeability and production flow.
Consequently, there is growing interest toward understanding the mechanism of dithiazine formation and quantification in natural gas Chromatotec® is currently developing a specific analytical system equipped with a preconcentrating unit, chromatographic column and a mass spectrometer detector for the identification and quantification of dithiazine in natural gas. This robust system is designed to work continuously 24/7 in the field while automatically generating analytical results.
The system uses H2 as carrier gas which can be generated by our Hydroxychrom hydrogen generator. To run the analytical system, only electricity and water are necessary. The MEDOR gas chromatograph can be added to the analytical system to quantify H2S and mercaptans from natural gas.
