摘　　要：利用ASPEN作为平台,针对20000空分装置,拟定全低压分子筛吸附净化、空气增压透平膨胀机制冷、全精馏无氢制氩、氧气外压缩的工艺流程,建立了相关精馏系统的计算模型,进行精馏系统计算,并以提高氧和氩的提取率为目标完成其模拟调试过程.在不增加空气量的基础上,通过精确的模拟计算辅助提高运行设备的氧和氩提取率.使氧的提取率达到99%以上,氩提取率达到80%以上.From 20000 air separation plants, full rectification low-pressure process of molecular sieve adsorption, compressor turbo-expander, full rectification argon production without hydrogen and oxygen external compression was specified. Simulation calculation was emulated with ASPEN to establish the corresponding simulation of rectification system for the calculation of it, and the recovery ratio of oxygen and argon without increasing the air flow rate was increased. It is expected that the oxygen recovery ratio is more than 99%, and the argonrs more than 80%.
