摘要
介绍了硫黄回收装置尾气提标单元的工艺原理和特点。详细分析了生产过程中遇到的问题并提出解决办法。通过有针对性地对尾气提标单元进行工艺改造,同时对硫黄回收装置停工过程工艺流程进行优化,实现了联合装置全运行周期内的达标排放,且连续达标运行超过600 d。为同类装置长周期达标排放技术改造提供参考。
The process principle and characteristics of tail gas standard lifting unit of sulphur recovery unit are introduced.The problems encountered in the production process are analyzed in detail and the solutions are put forward.Through the targeted process transformation of the tail gas standard raising unit and the optimization of the process flow of the shutdown process of the sulphur recovery unit,the standard emission within the whole operation cycle of the combined unit is realized,and the continuous standard operation exceeds 600 days.It provides a reference for the technical transformation of long-term up-to-standard emission of similar units.
