海水脱硫技术在船舶废气处理上的研究进展
A review of seawater desulphurization technology on ship exhaust treatment
摘要
Abstract
The situation of SOx emission from ships is becoming increasingly serious. Seawater desulphurization technology is paid great attention due to its advantages,such as low operation cost, abundant resources of desulfurizer and non-solid waste. The effects of alkalinity and salinity of seawater,metal cations such as Ca2+,temperature,liquid-gas ratio and SO2 initial concentration on desulfurization efficiency were analyzed. Improving alkalinity of seawater is proposed to be the most direct and efficient way to enhance desulfurization efficiency. Research hotspots,including how to increase alkalinity of seawater,how to decrease the size of desulphurization system and how to removal SOx and NOx simultaneously,were outlined. According to mobility of ship,problems existed in applying seawater desulfurization technology to ship were introduced. Without influence on reliability of desulfurization equipment,developing environmental and efficient additives will be a focus of study on improving alkalinity of seawater. How to oxidize SO32− efficiently in desulfurization tower provides a vital research orientation in term of reduction on the size of desulfurization system. Seawater desulphurization technology applied to ships in the future will be developed in a more efficient,economic and environment-friendly way.关键词
