为解决抚顺石化公司石油三厂连续重整装置原料短缺的问题，根据实际的工况条件，在小型试验装置上详细研究了大庆常压塔顶汽油脱砷脱氯工艺技术的可行性，并对几种脱砷脱氯工艺方案进行了论证。试验结果表明，通过对现有脱氯反应器的改造，采用脱砷－脱氯联合工艺技术，可将大庆常压塔顶汽油中的砷从１０００ｎｇ／ｇ以上脱除至１０ｎｇ／ｇ以下，氯从５μｇ／ｇ以上脱除至０．５μｇ／ｇ以下，循环气中的ＨＣｌ小于１μｇ／ｇ，完全满足连续重整装置工况的要求。对脱砷－加氢－脱氯汽油中碱金属和碱土金属的测定结果表明，不存在催化剂的金属流失问题。预计该工艺可为企业带来直接经济效益５６０万元／ａ。
In order to solve the problem of shortage of raw materials for the continuous reforming unit of the Third Plant of Fushun Petrochemical Company, according to the actual operating conditions, the feasibility of arsenic removal and arsenic dechlorination technology in Daqing atmospheric overhead petrol was studied in detail on a small test device. Several arsenic dechlorination process scheme was demonstrated. The test results show that the arsenic-dechlorination combined process technology of dechlorination reactor can be used to remove arsenic from above 1000ng / g to below 10ng / g in Daqing atmospheric overhead petrol, From above 5μg / g to below 0.5μg / g, the HCl in the recycle gas is less than 1μg / g, which fully meets the requirements of continuous reforming equipment. The results of the determination of alkali metals and alkaline earth metals in the arsenic-hydrogenation-dechlorination gasoline show that there is no problem of metal loss from the catalyst. The process is expected to bring direct economic benefits of 5.6 million yuan / a.
