【摘要】：本文对硫磺回收及尾气处理技术进行了综述。以武汉石化现有6万吨／年硫磺回收装置为基础,通过对装置运行现状的分析,结果表明：武汉石化现有6万吨／年硫磺装置存在一些工艺和设备选型、使用上的缺陷。液硫池尾气处理单元尾气回收处理工艺不完善,制硫单元切断阀门动作不灵活,仪表容易堵塞,溶剂再生处理单元胺液系统腐蚀情况突出,液硫泵故障率高等问题。在此基础上,提出了装置工艺优化和设备改造选型方案,实现了该装置安全环保生产。以武汉石化扩能改造和油品质量升级和原油劣质化为背景,根据中国石化的“硫磺装置作为环保装置应采取N+1配置的要求”的要求,提出了武汉石化公司新建8万吨／年的规模硫磺回收装置工艺方案和设备选型方案,这对其它硫磺回收装置的建设、优化与改造有一定借鉴意义。
[Abstract]:This paper summarizes the technology of sulfur recovery and tail gas treatment. Based on the existing 60,000 t / a sulfur recovery unit in Wuhan Petrochemical Company, the operation status of the unit is analyzed. The results show that there are some defects in the selection of process and equipment in the existing 60,000 t / a sulfur unit of Wuhan Petrochemical Company, the tail gas recovery and treatment process of tail gas treatment unit in liquid sulfur tank is not perfect, and the cutting off valve action of sulfur production unit is not flexible. The instrument is easily clogged, the corrosion of the solvent regeneration unit amine liquid system is prominent, and the failure rate of the liquid sulfur pump is high. On this basis, the process optimization of the device and the selection scheme of the equipment transformation are put forward. Based on the background of capacity expansion, upgrading of oil quality and poor crude oil quality of Wuhan Petrochemical Company, according to the requirement that sulfur unit should be used as environmental protection unit in Sinopec, the requirement of N _ 1 configuration should be adopted. A new scale sulfur recovery plant of 80,000 tons per year in Wuhan Petrochemical Company is put forward, which has some reference significance for the construction, optimization and transformation of other sulfur recovery units.
