摘　　要：随着合成氨生产过程变换压力等级的提高,传统的变换气脱硫塔在操作中遇到了脱硫效率下降、堵塔等问题。通过对传统变脱塔结构及脱硫工艺原理的分析,提出了变脱塔工艺的改进方案,经实践证明,方案合理、效果显著。As increasing transforms pressure in ammonia production process,the traditional shift gas de-sulfur tower encountered some problems,such as loss of efficiency of de-sulfurization,block of towers,and so on.By analyzing tower structure of the traditional shift gas desulfurization and the principle of the de-sulfur process,to put forward a proposal about the de-sulfur process.The improvement is reasonable,the effect is significant.
