摘　　要：利用ＡｓｐｅｎＰｌｕｓ软件作平台，建立了空分精馏系统的计算模型，以齐鲁二化空分装置的设计值及５种有代表性的实际操作工况进行模拟计算，计算结果分别与设计值及实际工况值吻合较好。并以提高氧气产量为目标，对５种工况进行模拟调优研究，找出提高氧气产量的途径，在不增加空气量的情况下，可提高氧气产量１５％左右。In this paper, an air separation distillation model in Aspen Plus was presented Air separation processes of the Second Fertilizer Plant of Qilu Petrochemical Co were simulated using this model,based on 5 actual operating conditions and the designed values. Results calculated from this model show well agreement with plant data. In addition, five cases of simulation and optimization were done to increase oxygen output. When the distillation units are operated at optimized parameters,the oxygen output will be increased by about 15%
