The use of CO2 is a proven antiscalant treatment for cooling water systems and is applied in several plants in Europe. As an alternative to pure commercial CO2, we have tested the use of (concentrated) power plant flue gases as a source of CO2. The challenge is to determine the minimal CO2 concentration in the flue gas for an efficient antiscalant treatment knowing that typical flue gas from a thermal power plant contains CO2 in the range of 4% for gas-fired power plant and 12% for coal-fired power plant.
