product for a plant with water cooling and less use of waste heat for process heat or cogeneration. These estimates assumed 2 barrels of product per ton of sub-bituminous coal (9,000 Btullb). In generating plants, cooling is the main use of water. Different studies have estimated different rates of water use for different technologies.
sions of pulverized-coal-fired power plants by 80 to 90 percent, but it would lead to a 90 percent increase in capital costs, a 15–30 percent de-crease in power generation efficiency, and doubled water consumption. When retrofitting or designing new pulverized-coal plants with CCS, water availability should be carefully evaluated.
