  • Patent number: 10821396
    Abstract: 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.
