| Abstract: | In order to reduce the energy consumption of a 1.4 Mt/a C3 and C4 separation unit， the simulation model for the C3 and C4 separation unit was established， the simulation and optimization for this unit was carried out by Petro-SIM process simulation software， and an optimization scheme was proposed according to the model. The results showed that the product quality indexes calculated by the simulation model were close to that of the actual product， which proved that the model could be used to optimize and guide the unit′s production. Under the processing capacity of 90% and the operating pressure of the iso-butane tower reduced from 0.93 MPa to 0.65 MPa， the mole fractions of propane， iso-butane and n-butane were 97.26%， 98.00%， and 90.00% respectively by simulation， and the steam saving could be 9.34 t/h theoretically. After the optimization operation， the actual steam saving was 9.72 t/h， corresponding to 7.506 million yuan per year. |
