Method and system for multi-stage compression of a gas using a liquid

A method of compressing a gas, comprising:

• providing a first chamber, said first chamber having a first volume of a liquid and a first volume of a gas;
• providing a second chamber, said second chamber having a second volume of the liquid and a second volume of the gas, wherein the second volume of the gas in the second chamber is at a first pressure and said first chamber and said second chamber are fluidly connected through a pump;
• and
• receiving a pressurized gas into the first chamber having the first volume of the liquid and the first volume of the gas and simultaneously pumping, using the pump, at least a portion of the first volume of the liquid in the first chamber to the second chamber such that the at least the portion of the first volume of the liquid pumped into the second chamber compresses the second volume of the gas in the second chamber to a second pressure greater than the first pressure,
• wherein the at least the portion of the first volume of the liquid pumped into the second chamber is admitted into the second chamber using a liquid admission mechanism so that the admitted liquid flows along an internal wall surface of the second chamber.

A system for compressing a gas, comprising:

• a first chamber, said first chamber having a volume of liquid;
• a second chamber, said second chamber initially having only at least a volume of a gas at a first pressure;
• a pump, wherein the pump is in fluid communication with the first chamber and the second chamber, wherein the pump pumps at least a portion of the volume of liquid contained in the first chamber to the second chamber containing the gas at the first pressure such that the portion of the volume of the liquid pumped into the second chamber compresses the volume of gas in the second chamber to a second pressure greater than the first pressure,
• wherein the portion of the volume of the liquid pumped into the second chamber is admitted into the second chamber via a liquid admission mechanism so that the admitted liquid flows along an internal wall surface of the second chamber.
