Abstract

A cylindrical scrubbing column having a cylindrical water-separator head is provided with an upwardly converging partition defining a diametrically extending elongated slot which communicates between the scrubbing region of the column and the head, the slot being aligned with a radial outlet for the flue gases from the head. The slot is flanked by a pair of longitudinally-extending impingement baffle register walls which remove water from the entraining flue gas by impingement baffle separation techniques and a further wall is provided at the end of the slot turned toward the radial outlet. The walls can converge in the direction of flow of the gas upwardly and the compartments behind the walls communicate with the radial outlet. The system has reduced pressure drop without detrimental effect to the separating efficiency.
