The problem of excessive total sulfur content in the purified gas of the low-temperature methanol washing unit of the coal to olefin project has been analyzed and modified based on the principle of low-temperature methanol washing process. By increasing the circulation volume of main washing methanol, reducing the temperature of circulating water, adjusting the amount of nitrogen gas extracted, controlling the amount of acidic gas, solving the problem of internal leakage in the bottom reboiler and top condenser of the thermal regeneration tower, and controlling the ammonia content in the methanol system Measures such as switching and cleaning the lean methanol filter have effectively improved the quality of lean methanol, ultimately reducing the total sulfur in the purified gas from 0.15 mg/L manually analyzed to 0.06 mg/L, meeting production requirements and ensuring safe and stable operation of the device
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
