A breakthrough in the analysis of dithiazine in natural gas

Jan 21 2022

Hydrogen sulphide (H2S) is a ubiquitous pollutant in natural gas, oil and gas applications; it is a danger to human health and the environment as well as being highly corrosive and noxious. A variety of methods are used to eliminate this pollutant, For many years, using MEA-triazine as a cat to the H2S mouse has proven to be arguably the most cost-effective and efficient solution. However this process precipitates the formation of dithiazine as a  kinetic by-product. Although the presence of dithiazine is a reliable indicator of the removal of H2S, its low level of solubility creates a new problem in the process, as its presence leads to a reduction in permeability and production flow. Therefore, we need to learn about the procedure of dithiazine formation and its quantification in natural gas. 

Chromatotec® offer an analytical system equipped with a pre-concentration unit, chromatography column and a mass spectrometer (MS) detector for detecting and quantifying dithiazine in natural gas. This rugged system operates 24/7 in the field and automatically generates analytical data. The new system uses hydrogen as its carrier gas which can be generated by Chromatotec’s Hydroxychrom generator. To operate the system, all you need is a supply of  electricity and water. Chromatotec’s MEDOR gas chromatograph (GC) can be integrated in the system to quantify H2S and mercaptans in natural gas.
