Abrégé
(EN)
Process for contacting two incompletely miscible phases whose contact is accompanied by heat evolution owing to mass transfer and/or a chemical reaction, in which a first phase is introduced into the lower region of a contactor and a second phase into the upper region of the contactor and conducted counter to the first phase in the contactor to obtain a treated first phase and an exhausted second phase, characterized in that a portion of the exhausted second phase is recycled into the contactor at at least one point between the upper region and the lower region. In the preferred embodiment, the first phase is a fluid stream comprising acidic gases, such as CO2, H2S, SO2, CS2, HCN, COS or mercaptans, and the second phase is an absorbent which comprises an aqueous solution of at least one organic and/or inorganic base.
