A distributor tray () for a column for contact between a gas (G) and a liquid (L) is provided wherein the distributor tray has a plurality of compartments defined on one face of the tray by secant partitions () which are perforated () to allow the flow of liquid between adjacent compartments. Each compartment includes at least one passage of the liquid through the tray or a chimney () projecting from the tray for the exclusive passage of the gas (G) through the tray. The shape of the chimney is identical to the shape of the compartment containing it, and the chimney has an internal volume at least equal to the volume of the compartment containing it.

The present invention relates to a gas-redirecting device presenting an upper plane and a plurality of gas-redirecting tubes comprising an inlet end and an outlet end. For each gas-redirecting tube, the orthogonal projections of the inlet end and the outlet end onto the upper plane have an over-lapping area of at most 50% of the total area of the upper plane covered by the orthogonal projections. Also provided is a liquid-gas contacting column comprising a gas-redirecting device, a floating support comprising a liquid-gas contacting column, at least two packed beds and a method for improving the efficiency of a liquid-gas contacting column which is based on redirecting the gas from a wetted zone of a lower packed bed to a wetted zone of the higher packed bed.
