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 wal…
