Abstract

International Maritime Organization MARPOL73/78 was published to limit sulfur dioxides of marine diesel engine, which regulated that in addition to using fuel of corresponding sulfur to meet emission requirements, marine exhaust scrubbing system can also be used to meet regulations. In order to develop marine exhaust scrubbing system, this paper is based on sodium alkali method to experimentally research the effect of liquid-gas ratio (L/G), scrubbing liquid pH and inlet temperature and exhaust flow rate of scrubbing tower on desulfurization efficiency. The results are as follows: when liquid-gas ratio is of 1.5-2.5 L/m3, scrubbing liquid pH is higher than 6.7, inlet temperature is lower than 200 °C and exhaust gas flow rate is of 1.5-1.91 m/s, the desulfurization efficiency can be more than 97.15 %. The influence rule of these parameters on desulfurization efficiency can be got and key process parameters in scrubbing tower operation can be obtained, which provides reference for the design and development of desulfurization system in medium scale.
