Abstract

A method and apparatus are described for contacting a gas with a liquid by injecting gas at high tangential velocity into a contacting zone so as to form a large centrifugal force in the zone and allowing the gas to transit across a liquid inlet in the zone so that liquid is drawn into countercurrent contact with the gas. One embodiment of the apparatus consists of a closed vessel (1) having an internal baffle (5), and inlet (3) for gas or vapor injection and a gas or vapor outlet (4). The internal baffle defines an upper gas-liquid contacting zone and a lower storage zone for liquid (8). Liquid is drawn into the contacting zone through the liquid inlet dip-pipe (7) and after contact with the gas can flow back to the storage zone via the peripheral gap (6).
