低温甲醇洗作为一种酸性气体处理方法越来越受欢迎，特别是在多联产系统中。在白杨Plus软件中对单段低温甲醇洗和两段低温甲醇洗两种结构进行了分析和模拟，以进行精馏性能模型和流程比较。对PC-SAFT模型进行了修正，对二元相互作用参数进行了修正，并利用实际工艺设计数据对修正后的模型进行了验证。确定修正后的PC-SAFT模型作为流程模拟的热力学性质模型。从酸性气体脱除能力、热回收、设备要求、能耗、环境排放和环境成本等方面对两种方案进行了比较。
Rectisol wash is becoming increasingly popular as a sour gas treating, especially integrated in the polygeneration systems. Two configurations of single-stage Rectisol wash and two-stage configuration are analysed and simulated in Aspen Plus for the property model rectification and the process comparison. The model PC-SAFT is revised for binary interaction parameters modification, and the revised model is verified based on practical process design data. The revised PC-SAFT is determined as the thermodynamic property model in the process simulation. The two configurations compare in the aspects of the acid gas removal ability, heat recovery, equipments requirement, power consumptions, and environment emission and environment costs.
