Abstract:

LSH-03G high-efficiency Claus tail gas hydrogenation catalyst are introduced, and the catalyst is commercially tested in an industrial installation. The catalyst has good preparation repeatability and activity, and meets the requirements of catalyst technical indicators. The industrial application of LSH-03G catalyst is carried out in No. 5 desulfurization station of Sinopec Chuaxi Natural Gas Exploration and Development Co., Ltd. The calibration results show that the parameters of the unit operate normally; The hydrogenation conversion rate of SO₂ is 100.00%, the average hydrolysis rate of organic sulfur is 93.45%, and the average CO conversion rate is 97.09%. The LSH-03G catalyst meets the requirements of No. 5 desulfurization station of the sulfur recovery unit of Sinopec Chuaxi Natural Gas Exploration and Development Co., Ltd. The total sulfur recovery rate of the unit is 99.96%, which meets the design index requirements of the unit.

Key words: Claus, tail gas hydrogenation, LSH-03G catalyst, hydrogenation conversion, hydrolysis of organic sulfur, CO conversion, total sulfur recovery rate
