System and method for providing a reserve supply of gas in a pressurized container

US-8746503-B2

Abstract

A gas storage and delivery system for restoring pressure as it is depleted from a pressurized container, includes a container holding a product under pressure to be dispensed from the container, a quantity of gaseous material under pressure, occupying a space in the container and applying to the product a predetermined pressure of from about 30 to about 180 psig, and a quantity of gas-adsorbing material, storing under pressure a quantity of the gaseous material and releasing it into the container in response to a decrease in pressure in the container, thereby restoring and maintaining a predetermined pressure in the container as product is depleted from the container, wherein the gas-adsorbing material is wetted with a release-promoting agent to promote release of the sorbed gas from the gas-adsorbent material. A process of filling the container is also disclosed.
