Abstract: A gas recovery system for a beverage dispensing system, the gas recovery system comprising: means for drawing gas from an at least partially used beverage container, a compressor downstream of said at least partially used beverage container; a gas separator downstream of said compressor, a gas storage vessel downstream of said gas separator; wherein in use the gas recovery system is configured to draw gas from the at least partially used beverage container and to separate said gas into component gases by passing said gas through said gas separator, and to selectively direct at least one of the separated component gases to said gas storage vessel.

Abstract: A beverage dispenser (10) includes a concentrate container (30) coupled to a connector (46). The connector (46) couples gas to the concentrate container (30), and couples concentrate from the container (30) to a dispensing valve (44). A combined carbonation and refrigeration unit (38) produces cold soda and provides cooling for concentrate lines (52, 54, and 56) and for water line (50).
