A method of improving the contacting of a gas and a liquid by injecting liquid, together with the gas in the form of substantially uniformly sized bubbles, into a vertical column of the liquid so as to introduce both a vertical downflow along the column axis and a rotational movement of the liquid-gas mixture about the axis. Preferably at least a major part of the liquid and a part of the gas is introduced tangentially near the top of the column, the remainder being introduced axially as a high velocity stream from the top of the column.

A method of contacting a gas and a liquid in a vertical downflow contacting column which has an upper zone and a lower zone and a central vertical axis, said method comprising introducing gas and liquid into said upper zone so that the gas is present in said upper zone dispersed in liquid in the form of bubbles, circulating liquid or liquid iwth gas bubbles dispersed therein in said upper zone to cause rotational flow substantially around said central vertical axis, feeding liquid or liquid with gas bubbles dispersed therein axially downwardly along said central vertical axis within said rotional flow in said upper zone, thereby to cause separation of bubbles from liquid in said lower zone to form bubble-free liquid therein, and removing said bubble-free liquid from said lower zone.
