• passing the gas through a spray-scrubber area with atomizing nozzles above the first structured packing;
• separating larger drops with a first demister that is above the spray-scrubber area;
• passing the gas through a hollow woven fabric having a surface, said hollow woven fabric placed above the first demister in a vertical direction with the surface disposed facing the at least one inner wall of the housing,
• spraying a washing liquid in the direction of the gas stream onto the surface of the woven fabric with two or more spray nozzles arranged around the woven fabric;
• and
• separating drops with a final demister above the woven fabric, said final demister having a demister rinsing apparatus.
