Method and apparatus for delivering pressurized gas

A method for pressurizing a fluid and delivering said fluid as a gas comprising sequentially:

• a. receiving a quantity of a fluid into an apparatus at an initial pressure and an initial temperature;
• b. pressurizing said quantity of said fluid to within a pre-determined pressure range wherein said initial pressure falls outside of and below said pre-determined pressure range;
• c. storing said quantity of said fluid;
• d. heating said quantity of-said fluid within a pre-determined temperature range and transforming said fluid to said gas, wherein said initial temperature falls outside of and below said pre-determined temperature range;
• and,
• e. delivering from said apparatus said gas at a pressure within said pre-determined pressure range and a temperature within said pre-determined temperature range.

An integrated apparatus for pressurizing a fluid and delivering a gas comprising:

• a. a casing assembly comprising an elongated thermally insulated body;
• b. a pump disposed at a first end of said casing assembly, said pump comprising:
• i. an intake opening for receiving said fluid at an initial pressure and an initial temperature;
• ii. a pressurizing device in communication with said intake opening, said pressurizing device capable of pressurizing said fluid to a pre-determined pressure wherein said pre-determined pressure is greater than said initial pressure;
• and,
• iii. a high pressure discharge passage in communication with said pressurizing device for discharging said fluid from said pressurizing device;
• c. a heater disposed within said casing assembly, said heater capable of warming said fluid to a pre-determined temperature, thereby converting said fluid to said gas, said heater comprising:
• i. a heater inlet for receiving said fluid;
• and,
• ii. a delivery outlet in communication with said heater inlet wherein said delivery outlet delivers said gas from said apparatus said heater thermally insulated from said pump;
• d. a conduit disposed within said casing assembly for receiving and delivering said fluid in a supercritical state from said high pressure discharge passage to said heater inlet;
• and
• e. thermal insulation interposed between said heater and said pump.

A method for pressurizing a fluid and delivering said fluid as a gas comprising sequentially:

• a. receiving a quantity of a fluid into an apparatus from a reservoir of said fluid stored at an initial pressure and an initial temperature;
• b. pressurizing said quantity of-said fluid to within a pre-determined pressure range wherein said initial pressure falls outside of and below said pre-determined pressure range;
• c. delivering said quantity of said fluid away from said reservoir where said fluid is thermally insulated from said reservoir;
• d. heating said quantity of said fluid to a temperature within a pre-determined temperature range and transforming said fluid to said gas, wherein said initial temperature falls outside of and below said pre-determined temperature range;
• and,
• e. delivering from said apparatus said gas at a pressure within said pre-determined pressure range and a temperature within said pre-determined temperature range.
