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.
