摘要:

kt/a硫磺回收装置是中化泉州石化有限公司12 000 kt/a炼油项目的配套环保装置,采用国内自行研发的先进硫磺回收技术进行设计和试运行。简要介绍了该大型硫磺回收装置的设计特点及工艺流程,并对在开工试运行期间低负荷工况下出现的问题进行了分析总结,可为装置长周期平稳运行提供指导。试车结果表明:硫磺回收装置运行平稳,尾气中SO₂的排放量符合国家环保部门的规定,生产的硫磺成品质量达到GB/T 2449-2006《工业硫磺》中规定的优等品级别,具有较好的环保效益和经济效益。 

Abstract:

The 380 kt/a sulfur recovery device is the supporting environmental protection device for 12 000 kt/a refinery project of Sinochem Quanzhou Petrochemical Co., Ltd, which adopted the domestic self-developed SSR sulfur recovery process. The design characteristics and technological process of the large sulfur recovery unit were briefly introduced. The start commissioning problems under the condition of low load were analyzed and summarized to provide guidance for unit long-periodic steady running. Commissioning results showed that the sulfur recovery unit runs smoothly, the emissions concentration of sulfur dioxide in tail gas was far lower than the standards prescribed by the national environmental protection department, and sulfur products meet the requirements of superior grade sulfur in the GB/T 2449-2006 Sulfur for Industrial Use. Therefore, it has good environmental and economic benefits.
