Environmental Performances of Various CCU Options in the Framework of an Integrated Chemical Plant

Several carbon capture processes are investigated to separate a part of the CO<sub>2</sub> contained in the flue gas of a coal-fired power plant located in a chemical integrated plant, with the objective of using it as a raw material in a production process. The expected results are to r...
