Abstract
Gas/liquid contacting apparatus comprising a normally substantially vertically extending column enclosing a plurality of substantially horizontal gas/liquid guiding units vertically spaced apart from one another and extending over substantially the cross section of the column. Each gas/liquid guiding unit comprising a plurality of alternating upwardly converging gas passages and downwardly converging liquid passages, the gas passages and the liquid passages alternating in vertical direction. The liquid passages have open upper ends, and are provided with bottomwalls and with liquid discharge openings at or near said bottomwalls. Each upwardly converging gas passage is provided with an open lower end and terminates at its upper end in a plurality of substantially horizontal, parallel walls having a length increasing in downward direction and forming a plurality of substantially horizontal, constricted gas outlets. The gas outlets direct the high velocity gas streams substantially horizontally towards liquid curtains coming substantially vertically from the lower end of a next upper liquid passage and substantially impinging on the walls forming said gas outlets.
