In order to investigate the effect of temperature of absorption liquid and exhaust temperature of diesel engine on decarbonization efficiency of marine decarbonization tower, the effect of temperature on carbon dioxide absorption efficiency in ship exhaust was studied by means of theory, experiment and simulation. Because of the particularity of the experiment, three exhaust temperatures of 25, 45 and 65 degrees celsius are mainly set up in this paper. The relevant experimental data are collected and analyzed under idle speed, 25% load condition, 50% load condition and 75% load condition, respectively. The experimental results show that under the same load, when the exhaust gas temperature increases, the absorption efficiency shows a downward trend. and the experimental exhaust gas temperature was simulated by Aspen plus software from 35 to 200 degrees celsius respectively. the simulation results show that the absorptivity decreases with the increase of temperature, and the simulation results are consistent with the experimental results, which has a certain reference for the design and operation parameters selection of marine decarburization tower.
