摘要
采用Aspen Plus软件对MDEA胺液脱碳过程进行模拟计算,物性方程选用ELECNRTL并对部分离子溶液无限稀释数据和主要传递性质进行修正。通过对主要传递性质、主要物流点工艺数据、吸收热、塔板温度分布等方面与专利商数据进行对比,计算结果与工艺包数据偏差≤5%,验证了修正后的ELECNRTL模型在MDEA胺液脱碳过程模拟应用的可靠性。
The Aspen Plus softwareis used to simulate the decarbonization process of MDEA amine solution. ELECNRTL is selected for the physical property equation, and the infinite dilution data of partial ion solutions and the main transmitting properties are corrected. By comparing the main transmitting properties, process data of main streams, absorption heat, tray temperature profile and other aspects with the licensor s data, the deviation between the calculation result and process package data is ≤ 5%, which verifies the reliability of the simulation application of modified ELECNRTL model in MDEA amine solution decarbonization process.
