【Abstract】 The problem of the high and low pressure depropanizer distillation system was discussed, and the cause of the problem was analysed. The technique and steps of the process flowsheeting were introduced. The distillation system was simulated using the Aspen Plus software. Based on the calculation results, the operation was optimized step by step. It was proved that the operation was more stable and the energy was saved.更多还原
