摘　　要：通过对不同粗苯加氢和萃取蒸馏工艺的比较,找出了各自的特点。并结合工程实际情况,阐述了不同的加氢和萃取蒸馏工艺对原料、能耗、产品的适应性的差异。建设新装置时,需要综合考虑多种因素来选择合理的工艺。By means of comparison on different crude benzol hydro-refining and extractive distillation processes, their individual features were found. In combination with project actual case, the difference of suitability on feedstock, energy consumption, and products by different hydro-refining and extractive distillation processes was described. When constructing new system, many factors should be comprehensively considered to select rational orocess.
