摘要
论述了低温气相加氢与萃取蒸馏工艺在苯精制过程中出现的问题及解决方案。低温气相加氢和萃取蒸馏技术可降低产品中硫含量,提高产品质量与收率。
This paper describes the problems found in the crude benzol refining process with the technology of low temperature gas phase hydrogenation and extractive distillation, and proposes corresponding measures. The technology of low temperature gas phase hydrogenation and extractive distillation can reduce the sulfur content in product, and improves product quality and recovery rate.
