| 摘 要： | 为分析Aspen HYSYS软件模拟的可靠度，进一步确定HYSYS软件在胺法脱碳再生工艺中的适用性，基于自主设计搭建的胺法脱碳中试试验装置，建立相应的HYSYS软件稳态仿真模型，对不同原料气气质、胺液流量、胺液配方、再生压力、再生温度下的胺液解吸率及再生能耗进行模拟、误差计算，分析HYSYS软件在胺法脱碳再生工艺中的适用性。研究结果表明，利用HYSYS软件模拟胺法脱碳过程中的再生工艺时，模拟结果随工艺参数的变化规律与试验结果总体保持一致，除个别不利于再生的工艺参数外，HYSYS软件的模拟适用性均较好；HYSYS软件中影响再生效果的5个工艺参数对模拟适用性影响较大的是再生压力，MDEA+MEA和TEA+MEA两种不同配方影响较小。另外，对再生能耗模拟误差影响较大的是再生温度，在一定塔底压力下，再生温度存在一个转折点，高于该温度时，再生能耗大幅度增加。本次验证过程中，再生温度115℃左右为一个转折点，但HYSYS软件的总体模拟能耗适应性均较差。 |

| Abstract: | In order to analyze the reliability of Aspen HYSYS software simulation and further determine the applicability of HYSYS software in the amine decarbonization regeneration process, based on the independently designed amine decarbonization experimental device, the corresponding HYSYS software steady-state simulation model is established. Simulation and error calculation are carried out on the amine desorption rate and regeneration energy consumption under different acid gas content, amine liquid flow, amine liquid formula, regeneration pressure and regeneration temperature, and the applicability of HYSYS software in amine decarbonization regeneration process is analyzed. The research results show that using the HYSYS software to simulate the regeneration process in the amine decarbonization process, the variation of the simulation results with the process parameters is generally consistent with the test results. Except for some process parameters that are not conducive to regeneration, the simulation applicability of the HYSYS software is good. Among the five process parameters in HYSYS software that affect the regeneration effect, the regeneration pressure has a greatest impact on the simulation applicability, while the two different formulations of MDEA+MEA and TEA+MEA have the least effect In addition, the regeneration temperature has a great influence on the simulation error of the regeneration energy consumption. At a certain bottom pressure, the regeneration temperature has a turning point. Above this temperature, the regeneration energy consumption increases significantly. During the verification process, the regeneration temperature is around 115℃, which is a turning point, but the overall simulation energy consumption adaptability of HYSYS software is poor. |
