粗苯加氢工艺路线的分析与比较

Analysis and comparison on crude benzol hydro-refining process

对不同的粗苯加氢和萃取蒸馏工艺进行了比较,分析了产品质量、品种、收率、能耗、投资等因素。结合实际情况,介绍了不同的粗苯加氢和萃取蒸馏工艺的特点。建设粗苯加氢装置时,综合考虑多方面因素,应优先选择低温加氢精制工艺。

The different crude benzol hydro-refining and extractive distillation processes were compared,the factors of product quality,variety,recovery yield,energy consumption and investment were analyzed.In combination with the actual situation,the features of different crude benzol hydro-refining and extractive distillation processes were introduced.When constructing crude benzol hydro-refining system,many factors should be comprehensively considered,therefore low temperature hydro-refining process should be selected firstly.
