| 摘 要： | 对现有粗苯精制工艺技术进行了比较,提出了一种全新的环保型粗苯萃取精制工艺。粗苯萃取精制工艺主要包括：1）预处理系统;2）苯精制与噻吩回收精制系统;3）甲苯、二甲苯精制系统;4）废水处理系统。该工艺的实施,不仅可以得到合格的三苯产品,而且可以回收价格昂贵的化工原料——纯度≥99%的噻吩。

| Abstract: | The crude benzene refined processes at present were compared in this paper. A new environmental protection process was put forward. This new process included pretreatment system, benzene refined and thiophene recovery system, toluene and xylene refined system, wastewater treatment system. Applying the process, it could be gained qualified benzene products, but also recovered expensive thiophene （ ≥99% ） for chemical materials. |
