| Abstract: | The ASPEN PLUS simulation software is used, the RK-ASPEN thermodynamic model is adopted, and the simulated analysis of the design working conditions of the liquid nitrogen wash unit in a plant is completed with success. On the basis of such an analysis a feasibility study is made of the original process flow in the light of great change in feed gas, and two schemes of reform are proposed, providing necessary technical support and theoretical guidance for the transformation of the plant, to be used as a reference for the revamp of various kinds of units. |
