Analytical Study on Process Optimisation of Deep-Cooling Air Separation Plant
Taking 60 000 Nm3/h deep-cooling air separation unit of a plant as the research object,Aspen Plus software is used to establish the model of the air separation unit,and the sensitivity module of Aspen Plus is used to analyse the process of each part of the lower tower of the main distillation tower of the model,and put forward the optimization scheme.Finally,the optimised process operation flow is applied in a plant to verify and analyse the energy-saving effect of the air separation unit through different loads,and to explore the specific economic benefits generated.
