Energy-Efficient Electrolysis Process Using Magnesium Electrode for the Alkalization ofSea Water

Year: 2015

Type: article

Abstract: In this paper, the effect of magnesium electrode on the alkalization of seawater by electrolysis was investigated in order to improve the performance of SOx scrubbers for ship exhaust. The simulated seawater was electrolyzed using carbon electrode or magnesium electrode, and the pH, voltage, current, input power, and alkalinity values were measured. The energy efficiency improvement of the alkalization process was evaluated. The results show that the alkalinity of the simulated seawater increased from 100 to 200 mg-CaCO3/L by electrolysis. It was also shown that with magnesium electrode the energy efficiency was significantly improved compared with that using carbon electrode because of its ability to suppress the generation of Cl2.
