摘要
针对硫磺回收装置开工过程中常用的加氢催化剂克劳斯尾气预硫化技术存在开工时间较长、开工烟气SO2排放量较大的问题,中国石化镇海炼油化工股份有限公司在第二套100kt/a硫磺回收装置开工过程中应用了尾气加氢催化剂超前硫化技术,分析了该技术的优势和难点,以及装置投产后的运行情况。结果表明,尾气加氢催化剂超前硫化技术的应用能够满足硫磺回收装置长周期运行工况的需要,并能缩短装置开工时间,节约装置开工时燃料、电等的消耗,减少装置开工期间的SO2排放量。
Long start-up period and more SO2 emission are the two problems existing in Claus tail gas hydrogenation process. To solve the problems, a sulfidation technology in advance of hydrogenation catalyst is applied for the first time in the second 100 kt/a sulfur recovery plant of Zhenhai Refining & Chemical Company. The advantages and difficulties of the sulfidation technology in advance and the pro- cedures were analyzed and introduced in detail. The application results show that the technology can sat- isfy the working need of the unit and cut the start-up time, save fuel and electricity consumption, and reduce the SO2 emissions.
