降低硫磺回收装置SO2排放浓度成套技术开发及应用

针对硫磺回收装置SO2达标排放的影响因素设立了防护措施，通过研发新型催化剂与工艺技术集成创新，开发了具有自主知识产权的“LS-DeGAS Plus降低硫磺装置SO2排放浓度成套技术”，实现了硫磺回收装置烟气中SO2排放质量浓度稳定低于50 mg/m3的目标，满足国家标准《石油炼制工业污染物排放标准》（GB 31570-2015）规定的SO2排放浓度要求。该技术具有无二次污染、投资少、能耗低、易实施的特点，已经在国内推广应用了58套。

DEVELOPMENT AND APPLICATION OF COMPLETE TECHNOLOGY FOR REDUCING SO2 EMISSION CONCENTRATION OF SULFUR RECOVERY UNIT

Aiming at the influencing factors on SO2 emission in sulfur recovery unit, the protective measures were established. By the integration innovation of new catalyst and process technology, the LS-DeGAS Plus complete technology for reducing SO2 emission concentration in sulfur recovery unit with independent intellectual property rights was developed. The concentration of SO2 emission in the flue gas of the sulfur recovery unit was reduced to below 50 mg/m3, which meets the requirements of the SO2 concentration specified in the national standard “Petroleum Refining Industry Pollutant Emission Standard” (GB 31570-2015). The technology has the characteristics of no secondary pollution, low investment, low energy consumption and easy implementation. It has been promoted and applied for 58 sets in China.
