摘　　要：针对低温甲醇洗系统酸性气解吸过程中存在的问题,提出相应技术改造方案。通过提高甲醇吸收量、降低闪蒸压力,可有效降低燃料气中CO_2、H_2S含量;提高气提氮气量,可以降低CH_4、CO、H_2等有效组分向大气中的排放量。改造后取得较好经济效益。Aiming at the problems existing in the process of acid gas desorption in the low temperature methanol washing system, the corresponding technical modification scheme is put forward. The content of C02 and H：S in fuel gas can be reduced effectively by increasing the absorption of methanol and reducing the flash pressure. Increasing the nitrogen content of gas can reduce the emission of the effective components such as CH4, CO and Ha into the atmosphere. After the transformation, the economic benefits become better.
