低压炼厂干气回收和蒸汽裂解相结合技术 据报道,鲁姆斯公司开发出低压炼厂干气回收与蒸汽裂解相结合的技术,该技术实际上是一种用丙烷作吸收剂的油吸收工艺。干气在用丙烷吸收之前,必须先脱除所含的杂质,例如C0_2、H_2S、C_2H_2、0_2、砷、汞及氨等杂质,可用胺洗脱除酸性气体,用加氢的方法脱除氧气和乙炔,用催化剂吸附方法脱除砷,再
Low-pressure refinery dry gas recovery and steam cracking combined technology It is reported that the Lummus company developed a low-pressure refinery dry gas recovery and steam cracking technology combined, the technology is actually a propane as an absorbent oil absorption Process. Before the dry gas is absorbed by propane, impurities such as C0_2, H_2S, C_2H_2, O_2, arsenic, mercury and ammonia and other impurities must be removed before use. Amines can be used to remove acid gases and hydrogen can be used to remove oxygen And acetylene, with a catalyst adsorption method to remove arsenic, and then
