| Abstract: |
| The traditional low temperature fractional distillation process was optimized, and based on the actual project data, the process flow before and after optimization were simulated by HYSYS software. Meanwhile, the two technologies were compared from parameters index and equipments numbers. The results show that the technology after optimization has the advantage of simpler flow, less equipment quantity, lower energy consumption and less cost. The results of HYSYS simulation show that the suitable work pressure of low temperature fractional distillation tower is 2.3 MPa, and the suitable plate number is 12 |
