The process of absorbing carbon dioxide in smoke using an absorber, comprises introducing the smoke (1) rich in carbon dioxide in a solution (4) absorbing the amines, regenerating the solution loaded with carbon dioxide (CO 2) in a regenerator and reintroducing into the absorber after cooling using an exchanger, washing the exchanger containing smoke loaded with CO 2with water in a washing section, recovering a flow rich in CO 2by condensation using the exchanger, supplying heat in the bottom of the regenerator using a boiler, and introducing hot pump circuits.

The hot springs are arranged in either in series, such that the heat flows in series through each of the spring to the cold source, or in parallel such that the heat flows simultaneously from the hot springs to the cold source. An intermediate heat source is introduced between the hot springs and the cold source at high temperature. A first circuit is established between hot springs and the intermediate source, and a second circuit is located between the intermediate source and the cold source. A refrigerant used in the heat pump circuits is a light hydrocarbon having 2-7 carbon atoms and heteroatomic ligands. |
