Studies on the technique of flue gas desulfurization with seawater focused on a simultaneous generation of electricity and drinking water
The innovation of the R & D project focuses on the use of brine, which is generated during the production of drinking water, in the flue gas desulfurization process of fossil fired power plants. The coupling of the system on both, the material and the energy side leads to a significant reduction of the necessary amount of water (in addition to the already known beneficial effect obtainable by the use of waste heat from the power plant). Thereby resources can be saved and the possibility of effective secondary treatment can be established. In addition, the catalytic effect of trace elements (iron, manganese, etc.) regarding the oxidation can be improved significantly. The salt content is reduced through the back mixing of brine before the discharge, to minimize negative impacts on flora and fauna.
The research project is funded by the German Federal Ministry of Economics and Technology via the AiF (AiF project no. 17118 N). The duration of the project is two years.
