Claim:
1. A method for compressing a gas entrained in a liquid comprising: providing a container rotatable about an axis with a plurality of capillary passages fixed in the container which lead radially to radially outboard ends terminating in a substantially annular container space; ejecting a plurality of jets of liquid through a gap filled with gas, each liquid jet creating a gas-liquid emulsion which is delivered to a corresponding capillary passage, each said liquid jet being continuously radially aligned with a respective input port of each said capillary passage, said emulsion created by a venturi effect in said gap, the introduction of the gas-liquid emulsion into radially inboard ends of said plurality of capillary passages promotes capillary action on said liquid in said capillary passages; rotating said container causing formation of gas bubbles in said capillary passages and compressing said gas bubbles towards the radially outboard ends of said capillary passages; collecting liquid and entrained compressed gas bubbles in said annular container space; and drawing off compressed gas released from bubbles buoyantly emerging from the gas-liquid mixture in said annular container space.
