摘　　要：为解决当前合成氨脱碳工艺过程中脱碳效果不佳无法满足0.2%要求的问题,在对MDEA脱碳工艺进行简单概述的基础上,对实际生产中的生产参数进行采集并初步分析了导致脱碳效果不佳的主要问题;而后,基于ASPEN PLUS软件建立MDEA脱碳工艺数值模拟仿真模型,重点对吸收塔压力、MDEA浓度以及贫液量对脱碳效果的影响进行仿真分析,得出最适宜生产参数。In order to solve the problem of poor decarbonization effect in the current synthetic ammonia decarbonization process and inability to meet the 0.2% requirement,based on a brief overview of the MDEA decarbonization process,the production parameters in actual production were collected and the main problems leading to poor decarbonization effect were preliminarily analyzed.Then,based on ASPEN PLUS software,a numerical simulation model for MDEA decarbonization process was established,with a focus on simulating and analyzing the effects of absorption tower pressure,MDEA concentration,and lean liquid volume on decarbonization efficiency,and obtaining the most suitable production parameters.
