摘　　要：主要探究了10万t/a甲醇联产合成氨装置中甲醇合成塔出口压力、外供驰放气量对合成氨装置PSA提氢量及氨醇产量的影响。同时也探讨了甲醇合成塔出口压力对氨醇联产装置总碳损失率的影响。通过在实际生产中,固定焦炉煤气量30 000 Nm^(3)/h,通过控制甲醇合成塔的压力,调节驰放气释放比例,以此获取不同的PSA提氢率控制氨醇产量。PSA提氢后的解析气回收再利用,做到利益最大化。根据甲醇及液氨不同的市场价格,通过控制合成塔出口压力及外供驰放气量,控制氨醇产量比例,做到效益最大化。This paper mainly explores the effects of outlet pressure of methanol converter and exhaust gas volume of external supply on PSA hydrogen extraction capacity and ammonia alcohol output of one hundred thousand ton methanol cogeneration ammonia plant.The effect of outlet pressure of methanol synthesis tower on total carbon loss rate of ammonia alcohol cogeneration unit was discussed.In actual production,fix the coke oven gas volume of 30000 Nm^(3)/h,control the pressure of methanol synthesis tower and adjust the release ratio of exhaust gas,so as to obtain different PSA hydrogen extraction rates and control the output of ammonia and alcohol.The analytical gas after PSA hydrogen extraction is recycled to maximize benefits.According to the different market prices of methanol and liquid ammonia,the output proportion of ammonia and alcohol is controlled by controlling the outlet pressure of the synthesis tower and the amount of exhaust gas from external supply,so as to maximize the benefit.
