The test results show that the influence of [O3]/[NO] ratio on NO oxidation was significant. The NO oxidization rate increased linearly as [O3]/[NO] ratio increased, and when the [O3]/[NO] ratio rose to 1, the NO oxidization rate came to 99.0%，98.3%和98.1% at ambient temperature, 150℃ and 200℃, respectively. The removal efficiency of NOx and SO2 reached 91.0% and 98.5% respectively, and the energy consumption was 56.4g NO/kWh. According to the actual ship out of stock exhaust system for analysis of desulphurization. The same time, absorption tower and the nozzles, spray layer, mist eliminators for selection the comparison is carried out between the new process, which is capable of removing SO2 and NOx from ship exhaust through a combination of ozone oxidation and sea water scrubbing, and SCR in every aspects such as the place occupied, investment and operating cost as well as DeNOx rate. And the study also focused on the feasibility of the new process in simultaneous removal of SO2 and NOx from Ship Exhaust. The International Maritime Organization (IMO) on the marine host nitrogen oxides (NOx) emission norms will come into effect in 2016, the provisions of NOx emissions cap of various speed marine host will be gradually lowered, so ozone oxidation - water absorption of the ship exhaust desulfurization a
