镇海炼化公司 7× 10 4 t/a硫磺回收装置引进荷兰Comprimo公司SCOT硫回收技术 ,采用二级常规Claus制硫加SCOT尾气净化工艺 ,设计总硫转化率 99.8% ,尾气中SO2 排放量和排放速率均低于国家标准。装置于 1999年 6～ 7月期间开工投运 ,并通过了性能考核。本文介绍了 7× 10 4 t/a硫磺回收装置设计特点和装置开工、考核及运行情况 ,并结合开工及生产过程中出现的问题进行讨论。同时介绍了为保证装置平稳运行进行的整改情况。
The 7 × 10 4 t / a sulfur recovery unit of Zhenhai Refining & Chemical Company introduced SCOT sulfur recovery technology from Comprimo Company of Netherlands. The second-stage conventional Claus sulfur plus SCOT tail gas purification process was adopted. The total sulfur conversion rate was 99.8%, SO2 emission and emissions Rates are lower than the national standard. Installation in June 1999 from June to put into operation, and passed the performance assessment. This article describes the design features of the 7 × 10 4 t / a sulfur recovery unit and the start-up, evaluation and operation of the unit, and discusses the problems encountered in the start-up and production processes. At the same time introduced to ensure the smooth operation of the device rectification situation.
