Concentration of acid gas hydrogen sulfide and carbonyl sulfide in low temperature methanol washing process
Acid Gas Hydrogen Sulfide and Carbonyl Sulfide Concentrations in Low Temperature Methanol Washing Process Details:



The crude furnace gas produced by the gasifier still contains a large amount of impurities, such as sulfides, etc. These harmful impurities are far from meeting the operation needs of the subsequent process and also cannot meet the environmental protection requirements. In addition, the large amount of carbon dioxide produced by the water gas shift unit also Purification treatment is required. The main principle of the low-temperature methanol washing process is to apply cold methanol as an absorption solvent, thereby removing carbon dioxide, hydrogen sulfide, carbonyl sulfide and other harmful acid gases. The low-temperature methanol washing technology is a physical method of gas purification .

In the methanol plant coal-to-methanol process, the methanol synthesis section has extremely strict control requirements on the content of hydrogen sulfide in the synthesis gas, and the content is required to be less than 0.1×10-6(V/V). At present, the methods used to analyze and measure hydrogen sulfide in gas include the determination of hydrogen sulfide content in natural gas, the methylene blue method, the coloring length detection tube method, the oxidation microcoulomb method for the determination of total sulfur content, and gas chromatography.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. selected gas chromatography for experimental discussions, mainly from the standard gas concentration changes, standard gas flow, pressure reducing valve material, column saturation and other aspects involved in the determination process of this method. The influencing factors in the process from curve making to sample measurement are discussed to ensure the accuracy of the method measurement, so as to guide the process operation correctly and prevent the occurrence of adverse consequences such as synthesis catalyst poisoning.
