SOx, NOx and COx account for a high proportion of the exhaust gas of ships which take low quality heavy oil as fuel, resulting serious impact on the global environment. In this paper, three types of treatment technology of ship exhaust gas, i.e. pre-treatment technologies, in-cylinder control technologies and post treatment technologies, have been introduced. Various single post-treatment technologies for the control of ship exhaust gas pollutants emission, including marine scrubber, selective catalytic reduction (SCR) and carbon capture and storage (CCS) were reviewed. The advantages and limitations of various post-treatment technologies of Sox, NOX and COx were analyzed. In practice, single pollutant treatment technologies were not effective for ship exhaust emission reduction. The development of new desulfurizers, the optimization of integrated process flow, feasibility of the system operation, could be the future direction of ship exhaust post-treatment technology. There are two restrictions for the development of the ship exhaust treatment technology, which are the space limit and the cost requirements.
