Abstract: Wash liquor/ suspension is sprayed at a velocity of at least 8 m/s, such that the atmosphere above the sump liquid surface contains at least 0.5 % wash suspension. Cleaned gas is discharged via a side outlet (13). An Independent claim is also included for a scrubbing tower having a sump of greater cross sectional area. The sump may be provided with a propeller agitator (15) for turning-in gas to the sump liquid in order to further increase gas-liquid contact time.
