Abstract
A method of compressing gas includes maintaining a volume of gas at a first pressure within a first chamber. Pressurized liquid is forced into the first chamber through a nozzle having a curved profile. Based on the Coanda effect, the liquid compresses the volume of gas to a second pressure greater than the first pressure. The liquid is separated from the gas in a second chamber while maintaining the gas at the second pressure to provide compressed, dry gas.
Claims20
A method for compressing a gas using a liquid, comprising:
- maintaining a first volume of gas in a first chamber, the first chamber comprising a first Coanda nozzle;
- maintaining a second volume of gas in a second chamber, the second chamber being fluidly connected to the first chamber and comprising a second Coanda nozzle;
- providing pressurized liquid into the first chamber through the first Coanda nozzle, wherein the pressurized liquid compresses the first volume of gas to a first pressure;
- and
- providing pressurized liquid into the second chamber through the second Coanda nozzle, wherein the pressurized liquid compresses the second volume of gas to a second pressure greater than the first pressure, wherein pressurized liquid is simultaneously provided to the first and second chambers, and wherein the first and second Coanda nozzles for the first and second chambers are configured to increase entrainment of gas in the pressurized liquid during compression.
A system for compressing a gas using a liquid, comprising:
- a first chamber configured for compressing gas to a first pressure, the low pressure chamber comprising a first Coanda nozzle;
- a second chamber configured for compressing gas to a second pressure greater than the first pressure, the second chamber being fluidly connected to the first chamber and comprising a second Coanda nozzle;
- and
- a pump assembly comprising:
- a first pump in fluid connection with the first chamber and configured to supply liquid to the first chamber through the first Coanda nozzle to compress gas to the first pressure;
- and
- a second pump in fluid connection with the second chamber and configured to supply liquid to the second chamber through the second Coanda nozzle to compress gas to the second pressure, wherein the second pump is arranged in series with the first pump, and wherein the first and second Coanda nozzles for the first and second chambers are configured to increase entrainment of gas in the liquid during compression.
