摘　　要：为避免烟气外排SO_(2)和外排水COD超标、降低综合塔操作负荷、缓解外排烟羽蓝烟拖尾现象,在济南炼化催化装置中开展了增强型RFS硫转移剂的工业应用实验研究。结果表明:当助剂占催化剂系统藏量2.8%,按新鲜剂补充量的3%稳定加注时,综合塔入口烟气SO_(x)平均总脱除率达到54.7%,碱液消耗量减少57.5%,外排废水TDS略有降低,烟气中的硫大幅向气体产品中转移,烟羽蓝烟拖尾现象明显改善;增强型硫转移剂的应用对裂化产物分布、产品性质和装置运行无负面影响。该工业应用研究表明,增强型硫转移剂可实现烟气污染物源头减排,并显著降低后处理措施负荷,可减少二次污染,具有一定应用前景。The industrial application trials of enhanced RFS sulfur transfer agent were conducted in SINOPEC Jinan Refining&Chemical Company in order to avoid exceeding the emission requirements for SO_(2)in the flue gas and COD in the external drainage,reduce the operating load of the integrated tower and alleviate the blue smoke trailing phenomenon of the external plume.The results showed that the average total SO_(x)removal rate in flue gas of the integrated tower inlet reached 54.7%and the lye consumption was reduced by 57.5%when the additive accounted for 2.8%of the catalyst system collection and was continuously added at a rate of 3%of the fresh agent replenishment.In addition,the TDS of outgoing wastewater was slightly reduced,the sulfur in the flue gas was transferred to the gas product substantially and the blue smoke trailing phenomenon of the flue plume was significantly improved under the above operating conditions.Most importantly,the application of RFS additive has little negative influence on product distribution,product properties and unit operation.Overall,The industrial application study showed that the usage of enhanced sulfur transfer agent could reduce the emission of flue gas pollutants at the source,lighten the load of post-treatment measures and suppress secondary pollution,and showed broad application prospects.
