Simulation Study and Analysis of Decarbonization Effect of N-methyldiethanolamine
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.
