摘　　要：介绍了利用纤维膜接触器技术脱除焦化液化气中硫醇的原理和工艺流程。脱硫醇后的液化气总硫含量基本维持在90 mg/m3以下,硫醇脱除率为96%左右,达到民用液化气标准,而且碱耗低,还可进一步回收丙烯,经济效益明显。The reaction principle and technological process of fibre-film contactor in Coker LPG Sweetening Process was simply introduced.Removal ratio of mercaptan was 96%.The sulfur content in Coker LPG sweetening kept with less than 90%basically,which was up to the standard of civil LPG.The method can reduce soda consumption and recycle was more propylene with great influence in economy.
