摘　　要：介绍了中国石化海南炼油化工有限公司S Zorb装置生产国Ⅴ汽油时在操作上做出的调整及装置运行情况,指出了影响装置长期稳定生产国Ⅴ汽油的主要因素和对策。通过调整操作和细化、强化吸附剂管理、严密监控再生器操作、提高关键设备的维护和管理水平等措施,装置分别经受住了超负荷运行、原料总硫大幅上升等情况的考验,能稳定生产硫质量分数不大于8μg/g的国Ⅴ汽油。期间原料硫质量分数平均为271μg/g(最高达600μg/g),精制汽油RON损失小于0.9单位,抗爆指数损失小于0.5单位。证明装置能长期稳定生产超低硫含量的国Ⅴ标准汽油。The operation adjustment and the operating conditions of S Zorb Unit for the production of gas- oline to meet Guo V gasoline specifications in SINOPEC Hainan Refinery and Chemical Co. , Ltd. are intro- duced, and the main factors affecting the long-term stable operation of the unit for the production of Guo V standard gasoline and corresponding countermeasures are proposed. The Guo V standard gasoline with sulfur no greater than 8 ppm was stably produced through operation adjustments and the detailed operations, strength- ening of the absorbent management, strict control of the operation of regenerator and improvement of the main- tenance and management of key equipment even when the unit was operating at the throughput exceeding the design capacity and the feed with higher sulfur. In the operation period, the average sulfur in the feedstock was 271 ppm （600 ppm max. ）, the research octane number （RON） loss of treated gasoline was less than 0.9 unit and anti-explosion index loss was lower than 0.5 unit, which indicates that the unit can produce ultra-low sulfur Guo V standard gasoline in long-term stable operation.
