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.
