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,
• wherein a first part of the plurality of gas-redirecting tubes is inclined towards the center of the plate and a second part of the plurality of gas-redirecting tubes is inclined toward the periphery of the plate, or
• wherein the gas-redirecting tubes of the plurality of gas-redirecting tubes are inclined so that:
• the orthogonal projection of all outlet ends and all inlet ends of the gas-redirecting tubes on the upper plane are disposed on a same circle, and
• the orthogonal projection of the outlet ends alternate with the inlet ends.
