摘　　要：中国石油化工股份有限公司天津分公司0.8 Mt/a连续重整装置在运行过程中,石脑油加氢装置出现原料硅含量超标和反应器床层压降上涨问题。通过分析问题产生的原因,对加氢工艺流程进行了技术改造,并通过应用加氢脱硅保护剂和增加脱硅保护罐方式解决了装置运行过程中出现的原料硅含量超标、加氢反应器压降增高等问题,实现了装置在不断变化生产条件下稳定高效运转。This paper introduces the problem that the raw silicon content exceeding standard and the pressure drop in the reactor bed rising in the naphtha hydrogenation unit during the operation of the 0.8 Mt/a continuous reforming unit of SINOPEC Tianjin Branch.Based on analysis of the causes of the problems,the technological transformation of the hydrogenation process was carried out,and the application of the hydrodesilication protector and addition of the desiliconization protection tank solved the problems in the raw material silicon content exceeding the standard and the rising of pressure drop in the hydrogenation reactor,which enabled stable and efficient operation of the unit under the ever changing production conditions.
