Nitrogen generator and uses thereof

A system for preparing and dispensing a nitrogen infused beverage;

• comprising:
• a bag-in-box beverage concentrate container;
• a first diaphragm pump controlling flow of a beverage concentrate through a beverage line from the bag-in-box container to a first flow controlling needle valve and from the first needle valve through a first back check valve to a liquid mixing point,
• a second diaphragm pump controlling water flow through a water line from a water supply to a liquid/gas contactor membrane unit and from the liquid/gas contactor membrane unit to a second flow controlling needle valve and from the second needle valve through a second back check valve to the liquid mixing point;
• a nitrogen generator in fluid communication with the liquid/gas contactor membrane unit via a nitrogen gas teed supply line;
• the liquid/gas contactor membrane unit;
• a nitrogen infused beverage line from the liquid mixing point to a beverage faucet;
• wherein
• the nitrogen generator comprises:
• an air compressor as a compressed air feed;
• a compressed air dryer;
• a compressed air storage tank having a moisture drain;
• a nitrogen membrane separator;
• a nitrogen storage unit;
• a pressure control unit;
• and
• a release valve for nitrogen from the nitrogen storage unit;
• the beverage faucet is a slow release faucet such that the infused beverage in the nitrogen infused beverage line remains under pressure during dispense of the beverage from the faucet, and
• the nitrogen gas feed supply line to the liquid/gas contactor membrane unit comprises a check valve preventing liquid flow from the liquid/gas contactor membrane unit into the pressurized gas supply line.
