| Abstract:The principle and model design of the flue gas desulfurization system of marine diesel engine are expounded，and the simulation model of the flue gas desulfurization system of marine diesel engine was built in Aspen Plus software and the system is simulated and optimized by Aspen Plus software.Based on the original model，the influence of SO2 flow rate in flue gas，reaction temperature，oxygen content in inlet flue gas，liquid-gas ratio and pH value of seawater on desulfurization performance was analyzed in a certain range，so as to obtain the control factors for the highest desulfurization efficiency.The research results can provide theoretical guidance for the optimal design of marine desulfurization system in order to improve the economy of ship operation. |
