船舶尾气脱硫治理技术现状与应用

针对全社会对船舶尾气排放控制日益严格,而远洋船舶所燃烧的重油会释放大量的尾气,这些尾气中主要为NOX和SOX等污染物,对海洋生态环境和沿海居民的身心健康构成严重威胁。文章介绍了国内外船舶尾气处理的各种方法及其优缺点,对各项技术发展趋势、经济性和应用前景进行了分析,并提出合理选择脱硫技术的建议。

In view of the increasingly strict control of ship exhaust emission by the whole society, the heavy oil burned byo-cean-going ships will releasea large amount of tail gas, which is mainly composed of pollutants such as NOX and SOX. It posesaserious threat to the marine ecological environment and the physical and mental health of coastal residents. This paper introducesvarious methods of marine tail gas treatment at home and abroad and their advantages and disadvantages, analyzes the developmenttrend, economy and application prospect of various technologies, and puts forward some suggestions for the reasonable selection ofdesulphurization technology.
