船舶废气洗涤脱硫技术现状及发展趋势

摘要

针对船舶排放控制日趋严格，介绍了国内外船舶动力装置废气洗涤脱硫技术的研究现状，并分析了其发展趋势、经济性和应用前景。研究表明，船舶废气洗涤技术是应对2015年IMO燃油含硫量限制的有效方法。洗涤系统虽然初投资较大，但成本可在1~4年内收回，具有广阔的市场前景。%As marine engine exhaust gas emission limitation is becoming more and more stringent, the research state of marine engine exhaust gas scrubber is introduced in detail, and the tendency, economy and prospect of the application of marine scrubbers are analyzed. The research shows that the exhaust gas scrubber is a valid measure to meet IMO 2015 regulation of fuel sulphur content. Although the initial in-vestment of scrubber is large, the capital can be recovered in 1~4 years, and is expected to have wide application in marine auxiliary products market.
