For cooling a gas by direct heat exchange with a cooling liquid, the gas (1) to be cooled is introduced into the lower region of a direct contact cooler (2). A first stream of cooling liquid (8) is fed into the direct contact cooler (2) above the point of introduction of th e gas (1). Cooled gas (5) is removed above the point of introduction of the gas (1) from the direct conta ct cooler (2). A liquid backflow (10) is drawn off from the lower region of the direct contact coole r (2). At least at times, a second stream of cooling liquid (13) with a temperature that is lower than that of the backflow (10) is fed into the liquid backflow (10) and combined with the latter to form a return flow (11).
