摘　　要：由于GB16297-1996标准中二氧化硫排放浓度的限制,小规模脱硫时,胺法脱硫+酸气焚烧已不可行,克劳斯装置必须加尾气处理。而络合铁法由于脱硫精度高、反应速度快和环境友好得到广泛应用,特别适宜于上述气体的脱硫。本文介绍了中国石油西南油气田公司天然气研究院CT络合铁法氧化还原技术及在自行设计的工业装置上进行工业试验的情况,指出了络合铁法在天然气和炼厂气脱硫中的应用前景。Due to limit of SO2 vent concentration in GB16297-1996,traditional amine+acid gas incineration methods may be impractical.Tail gas treating process must be added to Claus process to meet standards demands.The chelated iron liquid redox process enjoys widely use with high H2S removal efficiency and environmentally innocuous,the oxidation of H2S to elemental sulfur is very rapid.So it is very suitable for natural gas,acid gas,refinery fuel gas to removal H2S.In this paper,it is introducing developed achievement of CT chelated iron liquid redox process technology and commercial unit designed by RINGT.Simultaneity,the prospect of application in natural gas and refinery fuel gas was reviewed.
