| 摘 要： | 巴斯夫（BASF）的丁二烯萃取蒸馏工艺是以NMP（N-甲基吡咯烷酮）为溶剂的工艺，三种普遍用于丁二烯萃取溶剂中NMP是唯一无毒的溶剂。BASF公司投入了大量的精力改进了以NMP为溶剂的丁二烯萃取蒸馏的工艺。新工艺包括萃取蒸馏区。脱气区。蒸馏区和溶剂回收区。新工艺设备减少，投资降低10%，维护费用减少15%，装置安全性得到改善。

| Abstract: | BASF' s process for extractive distillation of butadiene is based on the solvent NMP which is the only solvent out of the three solvents used for butadiene extraction that was found to be non-toxic. BASF has invested a great effort in the revision of the process. The new process consists of extractive distillation section, degassing section, distillation section and solvent recovery section. New process has the following advantages: items of equipment is reduced, investment costs and maintenance costs are reduced by 10% and 15% respectively, plant safety is improved. |
