Reduction of Freshwater Usage of a Coal Fired Power Plant with CCS by Applying a High Level of Integration of All Water Streams

AbstractThe integration of the recently built 1 070 MW coal-fired unit in Rotterdam (Netherlands) with the proposed new 250 MW demonstration carbon capture unit of the Rotterdam Opslag en Afvang Demonstratieproject (ROAD) would lead to a substantial reduction in freshwater usage. This is partly due to the power plant design, the most relevant features being the seawater direct cooling and the limestone gypsum Flue Gas Desulfurization (FGD); and partly due to the high level of integration. This paper describes the water and waste streams of the capture plant, including quality and (re-) use in the power plant. The implications for a full scale capture are discussed
