摘要：

In order to study the desulphurization properties of seawater with jet bubbling reactor, experimental researches on SO2 removal from simulated marine waste gas were investigated in a self-designed jet bubbling reactor. The parameters influencing desulphurization efficiency, such as waste gas flow, seawater temperature, immersion depth, inlet concentration of SO2 and O2, were examined. Results showed that the absorption capacity of seawater scrubbing SO2 was up to 3.682 mmol·L-1 about 3.92 times that of deionized water. The desulphurization efficiency decreased with the increase in waste gas flow, seawater temperature and inlet SO2 concentration while it increased with increasing immersion depth and inlet O2 concentration. Desulphurization efficiency reduced linearly over desulphurization time. Increasing waste gas flow can increase total liquid phase mass transfer coefficient by 3.16%, which was less than that of seawater temperature. The absorption capacity increased significantly with increasing inlet O2 concentration. It increased from 3.682 mmol·L-1 to 7.463 mmol·L-1 as the inlet O2 concentration increased from 0% to 12%. © All Right Reserved.
