摘要: 远洋船舶运输作为三大运输体系之一,具有运输成本低、运输量大和安全性高等优点,但其尾气中NOX和SOX等也造成了严重的大气污染,亟待控制。文章梳理总结了目前国内外船舶发动机尾气NOX和SOX控制技术,并介绍了各技术的工作原理、优势及不足。该文认为基于尾气后处理系统的脱硫脱硝一体化技术,对船舶改动较少,且更适合旧船改装;而基于代用燃料或者燃料电池的新能源绿色船舶技术是未来船舶污染物控制、降低温室气体排放的最理想解决方案。

Abstract: As one of the three major transportation systems, ocean shipping has the advantages of low transportation cost, large transport capacity and high safety. However, NOX and SOX in marine engine emission also cause serious air pollution, demanding urgent control. This paper summarizes the current control technologies of NOX and SOX in marine engine emission at home and abroad, and introduces the working principle, advantages and disadvantages of each technology. It is believed that the integrated technology of desulfurization and denitration based on the exhaust gas treatment system is more suitable for refitting old ships due to less modification to the ships. However, the new energy green ship technology based on alternative fuels and fuel cells is the most ideal solution for the control of ship pollutants and the reduction of greenhouse gas emissions in the future.

Key words: marine engine emission, desulfurization, denitration, emission control
