    Abstract: A reaction vessel including an oxygen-containing gas chamber separated from a source gas chamber by an oxygen-permeable membrane that allows oxygen selectively to pass therethrough to contact and react with source gas contained in the source gas chamber. The ratio of at least one of (i) the volume of the oxygen-containing gas chamber to the total volume of the vessel and (ii) the volume of the source gas chamber to the total volume of the vessel, is outside a range within which explosion would occur if the oxygen-containing gas and source gas were allowed to combine directly. Preferably, the ratio also is outside a range within which explosion would occur if the oxygen-containing gas and products resulting from reactions between oxygen supplied through the oxygen-permeable membrane and the source gas were allowed to combine directly. The vessel is safer to operate in that the risk of explosion, due to direct mixing of the gases when the oxygen-permeable membrane is damaged or cracked, is greatly reduced.

    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.
