对3种脱砷脱氯方案进行了研究。结果表明,采用脱砷方案可将原料中的砷氯含量脱出至满足重整的进料要求,但需增设一个脱砷反应器;采用脱砷脱氯方案不能将原料中的氯含量脱出至满足重整进料小于0.5μg·g-1的要求;采用脱砷-加氢-脱氯联合工艺方案,将装置现有的脱氯反应器改为脱砷-加氢-脱氯反应器,可将原料中的砷氯含量脱出至满足重整进料的要求,该工艺方案对重整装置进行技术改造是切实可行的,它将为企业带来较大的经济效益。
Three arsenic removal dechlorination programs were studied. The results show that the arsenic removal program can be used to release the arsenic and chlorine content of the raw materials to meet the feed requirements for reforming, but a dearsenification reactor is required. With the arsenic removal and dechlorination scheme, the chlorine content in the raw materials can not be released Re-feed less than 0.5μg · g-1 requirements; the use of de-arsenic - hydrogenation - dechlorination process scheme, the device dechlorination reactor to de-arsenic - hydrogen dechlorination reactor, The arsenic chloride content in the raw material can be prolapsed to meet the requirement of reforming feed. The technological scheme of the reforming device is feasible and will bring greater economic benefits to the enterprise.
