由中国石化洛阳石化工程公司炼制研究所研制出的LHS-1型高效脱硫剂,适用于油田气、天然气、炼厂干气、液化气等气体脱硫(包括H_2S和COS)。实验表明,该产品与常用的单乙醇胺、二乙醇胺相比有以下优点:①反应热低;②在CO_2、H_2S同时存在时,对H_2S具有足够的选择性; LHS-1 high efficiency desulfurizer developed by SINOPEC Refining Research Institute of Luoyang Petrochemical Engineering Company is suitable for gas desulfurization (including H 2 S and COS) of oil gas, natural gas, refinery dry gas and liquefied gas. Experiments show that the product has the following advantages compared with the commonly used monoethanolamine and diethanolamine: (1) low reaction heat; (2) sufficient selectivity to H 2 S when CO 2 and H 2 S coexist;
