石油炼化企业烟气脱硫技术研究进展

石油炼化企业由于烟气特点、排放特征和减排设施的差别,导致了各炼化企业所采用的烟气脱硫技术的差别较大,尚无成熟、有效、经济的烟气脱硫技术,各炼化企业需要采用的二氧化硫减排技术差别也较大,选用适合炼化企业烟气脱硫的可行工艺技术具有重要现实意义。综合分析了目前国内外已工业化应用的主要烟气脱硫工艺、原理、技术的优缺点以及石油炼化企业烟气脱硫技术的发展趋势,为石油炼化企业烟气脱硫技术研究提供了借鉴和参考依据,并对石油炼化企业未来烟气脱硫技术的研究和选用提出了建议。

The Research Progress of Flue Gas Desulphurization Technique in Petroleum Refining Enterprises

The differences of flue gas and emission characteristics and the emission reduction facilities in petroleum refining enterprises result in the differences of their flue gas desulphurization(FGD) techniques which are far from matured,efficient and economical.Besides the sulfur dioxide emission reduction techniques adopted by different petroleum refining enterprises differ,therefore choosing feasible FGD techniques for petroleum refining enterprises has important practical significance.In this paper,we analyze the advantages and disadvantages of FGD procedures,principles and techniques which are under industrial applications at home and abroad and the development trend of FGD in petroleum refining enterprises in order to propose a reference frame for the petroleum refining enterprises.We also make some suggestions on the future FGD technique study and selection.
