摘　　要：对某厂低压含烃特殊原料气进行低温甲醇洗工艺设计,该原料气属于低压进料,且含有苯等有机烃类。针对原料气具体特点,设计了2套低温甲醇洗工艺,工艺Ⅰ是采用传统11塔低温甲醇洗方案,工艺Ⅱ采用9塔低温甲醇洗方案。借助Aspen Plus模拟分析表明,2套工艺均能达到净化要求,工艺Ⅱ较工艺Ⅰ有较好的节能及净化效果。对以后低压含烃特殊原料气的净化提供了参考。Rectisol processes are designed for special low-pressure feed gas containing hydrocarbon components,such as benzene and other organic hydrocarbons,for a factory. Given the specific characteristics of feed gas,two sets of Rectisol processes are designed as process Ⅰ and process Ⅱ. Process Ⅰ adopts traditional Rectisol flowsheet with 11 towers. Process Ⅱ adopts Rectisol flowsheet with 9 towers employed. According to the simulation analysis by Aspen plus,both processes can meet the purification requirements. Process Ⅱ shows better energy saving and purification effect than process Ⅰ. This work provides a reference for the purification of low-pressure special feed gas containing hydrocarbon components.
