Abstract:
In this paper,the main absorption collumn of cryogenic methanol washing unit of Hulun Buir Jinxin Chemical Co.,Ltd. is simulation-calcuated based on the process simulation software of Aspen Plus, The experiment values and software-calculated values of gas liquid equilibrium and liquid-liquid equilibrium for main components of the system are compared in a matching method, verifying the accuracy of the selected PSRK physical property method on system calculation,and then the charts on component distribution and temperature variation within the mair washing tower are simulation calculated,and the operation conditions of the main washing tower under different working conditions are analyzed.
