Fixed automatic gas chromatographs Хромат-900 are designed for qualitative and quantitative analysis of gas (vapor) phases of organic and inorganic substances at monitoring of technological processes, such as :
Хромат – 900-1, -2 – for component analysis of gas at installations of rectification and raw hydrocarbon pyrolysis, cracking, impurity content in pure gases, determination of component content of hydrocarbon gases, combustion heat, relative density, Wobbe index, including natural, liquefied, coke oven or associated gases, analysis of combustion gases injected into the atmosphere, contaminants measuring at the level of maximum permissible concentration in atmosphere and maximum permissible concentration in working area etc.;
Хромат – 900-3 – for component analysis (hydrocarbons, oxygen, nitrogen, carbon dioxide) and sulfur content (hydrogen sulfide, mercaptans) of hydrocarbon gases, including natural, liquefied, coke oven or associated gases, technological process monitoring in desulphuration systems etc.;
Хромат – 900 –4 for sulfur content analysis (hydrogen sulfide, mercaptans) of hydrocarbon gases, including natural and associated gases, technological process monitoring in Claus kilns, in desulphuration systems etc.;
Хромат –900 –5 for measuring of mole fraction of nitrogen, oxygen, carbon dioxide , hydrocarbons С1 – С5 and С6 + higher contained in flammable natural gas and calculation, on the basic of measured component content, physicochemical parameters of flammable natural gas quality– combustion heat, density, relative density and Wobbe index according to ГОСТ 31371.1-2008, ГОСТ 31371.2-2008, ГОСТ 31371.7-2008, ГОСТ 31369-2008, ГОСТ 31370-2008.
