Abstract:
1. A distributor for a liquid in a gas-liquid contacting vessel, comprising: a first member forming a plurality of apertures permitting a liquid to pass there-through; a first compartment coupled to the first member forming a barrier proximate to a perimeter of a first aperture of the plurality of apertures, wherein the first compartment forms a hole at a first height; a second compartment coupled to the first member forming a barrier proximate to a perimeter of a second aperture of the plurality of apertures, wherein the second compartment forms a hole at a second height different from the first height with respect to the first member; and a third aperture of the plurality of apertures that does not include a compartment forming a barrier proximate to a perimeter thereof so that the third aperture is configured to permit liquid to pass therethrough to facilitate gas-liquid contacting during normal operation; wherein the first member is configured for counter-current flow of liquid and gas where the liquid travels generally downward through the plurality of apertures and further comprising a riser coupled to the first member to allow gas to travel generally upward therethrough, the riser having a riser wall having a riser height above the first member that is higher than the first height and the second height and is configured to restrict liquid from entering the riser and interfering with gas traveling upward through the riser during operation.
