摘要
中低含硫天然气脱硫技术目前主要包括:干法、络合铁法和生物法(正在大力开发中的)。相对于传统的(醇胺法脱硫+克劳斯法硫磺回收+尾气处理)工艺路线,它们具有净化度高,能耗较小,投资较少,环境友好等特点,可按不同工况广泛应用于边远分散气井所产天然气脱硫、醇胺法装置产生的酸气及克劳斯装置的尾气达标处理等的工艺领域。
The medium and low HeS-bearing natural gas desulfurization technologies at pres- ent mainly include dry desulfurization, chelated iron process and biological desulphurization (be- ing developed). Compared with the conventional process flow (i. e. alcohol-amine desulfuriza- tion, Claus sulfur recovery and tail gas treatment), these technologies have advantages such as high purification degree, relatively lower energy consumption, relatively lower investment, and environment-friendly, etc. , and have been widely applied to desulfurization of natural gas pro- duced from remote scattered gas wells, standard treatment sour gas from amine units and tail gas from Claus units, and other processes.
