Abstract: A method when extracting solvent and heat from a gas (B) to absorb solvent in a solution (D) containing solvent and one or several absorbents with strong affinity to the solvent, wherein the absorption takes place so that gas (B) and solution (D) is contacted in parallel flow mainly on one side of a heat exchanger, where the heat liberated at the absorption simultaneously is transferred indirectly or regeneratively to a cooling medium (F, G), which meets the absorption media in counter flow.
