METHOD AND APPARATUS FOR CONTACTING GAS AND LIQUID

摘要

A method of contacting a gas and a liquid comprises providing an elongate substantially cylindrical reactor (1) having adjacent a first end thereof an inlet region (4) of reduced cross sectional area, introducing at least some of the gas and/or liquid into the inlet region in a direction tangential to the longitudinal axis of the reactor (1) by means of inlet (2) to cause rotational flow within the inlet region and therefrom into the remainder of the reactor and at such a velocity as to cause more intimate mixing of the liquid and gas. Additional gas and/or liquid may be introduced through a second inlet (6) disposed at an intermediate region of the reactor so arranged that the fluid introduced therethrough flows in a direction either generally longitudinal of the reactor, or in a rotational direction.
