Abstract: Apparatus for creating gas-liquid interfacial contact conditions for highly efficient mass transfer between gas and liquid includes a gas-liquid contactor assembly including a hollow porous tube surrounded by an outer jacket defining a gas plenum between the jacket and the porous tube; a liquid feed assembly including a nozzle for injecting liquid into the porous tube in a spiraling flow pattern around and along the porous tube; a gas-liquid separator assembly at the first end of the porous tube including a nonporous degassing tube coaxially aligned with and connected to the porous tube, a gas outlet port coaxially aligned with the degassing tube to receive a first portion of gas flowing from the degassing tube, a first gas duct coaxially aligned with and connected to the gas outlet duct to convey the first portion of gas therefrom; and a liquid collection assembly. A second gas discharge assembly to collect and convey gas from the first end of the porous tube is also disclosed.

Abstract: A method of optimizing and controlling gas-liquid phase chemical reactions includes the steps of introducing a liquid reactant to the hollow interior of a cylindrical porous tube in a thin film following a spiral flow pattern around and along the wall of the tube; controlling the physical characteristics of the liquid film and the flow pattern followed by the film through the tube; mixing a gas reactant and an inert gas in preselected proportion; sparging the mixture of gas reactant and inert gas through the wall of the tube and into the liquid film to form a multiplicity of gas bubbles in interfacial contact with the gas; allowing the gas reactant and the liquid reactant to chemically react; segregating the remaining gas from the liquid within the tube; and separating the cleaned liquid stream from the contaminant laden gas stream.
