| Abstract: |
| The sulfolane extractive distillation process is successfully commercialized in benzene extraction unit with a production capacity of 100×103 t/a in Qingyang Petrochemical Company. The operation results show that the purity of benzene is 99.95％,the crystallizing temperature of benzene is above 5.4 ℃, the recovery efficiency is 99.81％ and the energy consumption is 19.35 kgE0/t. Besides, some problems during the operation, such as extractive distillation flooding,removal of C6 tower energy waste, white earth inactivation are analyzed, and the solutions are carried out. |
| Key words: benzene sulfolane extractive distillation white earth inactivation |
