Gas redirecting device for liquid-gas contacting column

A gas-redirecting device for a liquid-gas contacting column, the gas-redirecting device comprising:

• a plate presenting an upper plane and having a plurality of through-holes allowing a gas to pass through the plate;
• a plurality of gas-redirecting tubes, each gas-redirecting tube comprising an inlet end and an outlet end and being fluidly connected to a through-hole of the plate and;
• wherein for each gas-redirecting tube, the orthogonal projections of the inlet end and outlet end onto the upper plane have an overlapping area of at most 50% of the total area covered by the orthogonal projections of the inlet end and outlet end.

A method for improving the efficiency of a liquid-gas contacting column having at least a first packed bed and a second packed bed positioned higher than the first packed bed, each bed having a wetted zone differentiated by the liquid load therethrough, comprising the following step:

• redirecting a gas from the wetted zone of the first packed bed to the wetted zone of the second packed bed,
• wherein the wetted zone of the first packed bed and the wetted zone of the second packed bed are offset from one another with respect to a vertical line.
