　　In response to the problem of excessive H2S in purified gas during low-temperature methanol washing process, combined with practical operating experience, corresponding treatment measures are proposed to ensure that the purified gas at the outlet of low-temperature methanol washing meets the standard

　　Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses gas chromatography to determine the operating parameters of hydrogen sulfide and carbonyl sulfur in purified gas, resulting in good peak column efficiency, high separation, accurate measurement results, and good repeatability. The optimized operating parameters can quickly separate hydrogen sulfide and carbonyl sulfur from gas components such as carbon dioxide, oxygen, nitrogen, methane, carbon monoxide, methanol, etc. The detection speed is fast and the detection limit is low, which can well meet the requirements of the process for detecting hydrogen sulfide and carbonyl sulfur in purified gas
