| Abstract: | A complex liquid-nitrogen wash unit was characterized by complex technology and integrated energy system. In this paper, the designed process conditions of the unit were simulated by Aspen Plus process simulation software. The RK-ASPEN thermodynamic model can exactly describe the thermodynamic model of this unit. A feasible and reasonable revamp scheme is proposed based on this kind of model which focuses on feed gas condition changes with no purge gas. |
