环保型粗苯萃取精制新工艺的设计开发

Design Development of Environmental Protection New Process for Crude Benezene Extractive Distillation Refining

开发的粗苯萃取精馏法是一种环保型精制新工艺,开创了国内第三条苯精制的工艺技术路线,该装置为国内首套规模最大的苯萃取精制装置。不仅可以得到合格的三苯产品,而且得到昂贵的化工原料—纯度≥99%的噻吩。

The developed crude benezene extractive distillation refining method is an environmental protection new process and initiates the third refining method of benezene in China.The plant is the first set of the largest scale home-made crude benezene extractive distillation refining.Not only the qualified benzene products,but also the expensive chemical material of thiophene(≥99%) can be obtained.
