粗苯加氢精制装置装车尾气治理工艺应用

The Application of Loading Off-gas Treatment Process for Crude Benzol Hydrofining Unit

重点对目前国内粗苯加氢精制装置应用较为广泛的几种装车尾气治理工艺进行对比,对各工艺存在的优缺点进行分析和研究,认为莱钢焦化厂应用的活性炭吸附工艺具有明显的优势,在同行业中具有较高的推广价值。

The paper focused on the comparison among several loading off-gas treatment processes widely used in current domestic crude benzol hydrofining units, and the analysis and study on the advantages and disadvantages of each processes was carried out, it was showed that, the activated carbon adsorption process used in eoking plant of Laiwu Steel had obvious advantages, and was of high popularization value in the same industry.
