Abstract: The invention relates to a method and apparatus for carrying out gas scrubbing, wherein gas is led through a washing column (T) from bottom to top, and washing material is led through the column (T) from top to bottom. At least two washing sections (WS1, WS2) are arranged one above the other in the washing column (T), of which the upper section (WS2) is delimited at the bottom by a riser base (K). At least a portion of the washing material loaded in the upper washing section (WS2) is drawn off at a draw-off point (A) provided in the area of the riser base (K) and is introduced into the lower washing section (WS1) as washing material at an introduction point (E) provided in the area of the lower washing section (WS1). A heat exchanger device (6) is interposed after the draw-off point (A) and before the introduction point (E) in the flow direction. The flow through the heat exchanger (6) is ensured solely by the hydrostatic pressure of the washing material, which results from the difference in height between the draw-off point (A) and the introduction point (E). A pump is dispensed with in this case.
