【Abstract】 Simulation and optimization of multicompnent distillation with the nonequilibrium stage model:METSH equations were introduced in this paper. A new and apllied way was advanced and the astringency of equations was greatly increased and more steadly .In the process of optimizing,a optimal function was established and used to calculate optimal result,and it’ll guide production.更多还原
