摘　　要：为了解决合成氨生产中PSA提氢处理能力不足、氢气损耗大等问题,本文主要对15万吨/年合成氨PSA变压吸附技术做优化研究,对变压吸附工艺进行了优化设计,采用N_(2)再生+微动力回收工艺技术,解决了变压吸附技术在合成氨生产过程中气体损失问题,达到节能降耗增产目的。PSA提氢装置技改投运后,系统出口CO_(2)含量小于0.1%,氢气回收率高于98.5%。本文对于相关研究工作有一定的参考作用。In order to solve the problems of insufficient PSA hydrogen extraction capacity and large hydrogen loss in the production of synthetic ammonia,we focuses on the optimization of PSA pressure swing adsorption technology of 150000t synthetic ammonia.Using the N2 regeneration and micro-power recovery technology,the problem of gas loss in the process of synthetic ammonia production by pressure swing adsorption technology was solved,and the purpose of energy saving,consumption reduction and increase production was achieved.After the PSA hydrogen extraction device was modified and put into operation,the CO_(2) content at the system outlet is less than 0.1%,and the hydrogen recovery rate was higher than 98.5%.This article has certain reference function for related research work.
