F15B 21/06

Abstract:

A method of compressing a gas includes pumping, using a pump, at least a portion of a liquid contained in a first chamber to a second chamber containing a gas at a first pressure such that the portion of the liquid pumped into the second chamber compresses the gas in the second chamber to a second pressure greater than the first pressure, wherein the portion of the liquid pumped into the second chamber is admitted into the second chamber so that the admitted liquid flows along an internal surface of the second chamber.

James Durand - Columbus OH, US

International Classification:

F04B 39/00
B01D 53/18
B01D 53/14

Abstract:

A method of compressing a gas includes maintaining a first volume of liquid in a first high pressure chamber and maintaining a first volume of gas in a second high pressure chamber, wherein the first volume of gas is at a first pressure and the first high pressure chamber and the second high pressure chamber are fluidly connected through a high pressure pump. A pressurized gas is forced into the first high pressure chamber having the first volume of liquid and simultaneously pumping, using the high pressure pump, at least a portion of the first volume of liquid in the first high pressure chamber to the second high pressure chamber, wherein the first volume of liquid pumped into the second high pressure chamber compresses the first volume of gas in the second high pressure chamber to a second pressure greater than the first pressure.

James Durand - Columbus OH, US

International Classification:

F17C 5/06

US Classification:

417 54, 417103

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.
