    Abstract: With a method or a device for producing 1,2-dichloroethane or ethylene (di)chloride (EDC) with the use of a circulating reaction medium and a catalyst, whereby ethylene and chlorine are supplied to the reaction medium, the goal is to permit the catalytic chlorination of ethylene in a manner that is particularly gentle to the product. This is achieved in terms of the method and by other means in that the ethylene or chlorine gas are introduced into the reaction medium by means of microporous gas diffuser elements for producing gas bubbles with a diameter of 0.3 to 3 mm.

    Abstract: An osmotic device that, following the imbibition water vapor, provides for the controlled release of a beneficial agent to a non-aqueous environment. The device comprises a hydrophilic formulation and a beneficial agent, surrounded by a wall. The wall is formed at least in part of a semipermeable hydrophobic microporous membrane having an average pores size between about 0.1 .mu.m and 30 .mu.m. The pores are substantially filled with a gas phase. The hydrophobic membrane is permeable to water in the vapor phase and the hydrophobic membrane is impermeable to an aqueous medium at a pressure less than about 100 Pa. The beneficial agent is released, for example, by osmotic pumping or osmotic bursting upon imbibition of sufficient water vapor into the hydrophilic formulation. The high water fluxes attendant with these vapor-permeable hydrophobic membranes facilitate the delivery of large quantities of beneficial agents without requiring large surface areas (quantities) of hydrophobic microporous membrane. In addition, use of vapor-permeable hydrophobic microporous membranes allow osmotic devices to be used in environments having limited water availability, such as air or soil.

    Abstract: Apparatus for optimizing gas-liquid interfacial contact for molecular mass transfer between gas and liquid comprises 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; a liquid collection assembly; and a second gas discharge assembly to collect and convey gas from the first end of the porous tube. A method of optimizing gas-liquid interfacial contact comprises the general steps of introducing a stream of liquid 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; sparging gas through the wall of the tube and into the liquid film at a preselected flow rate so as to create a two phase gas-liquid froth around the wall of the tube and a discrete column of gas in the central portion of the tube; maintaining the froth flow in a radial force field so as to prevent mixing of the froth and gas in the central column; removing gas forming the column from both ends of the tube; and removing liquid from the tube.
