Abstract
Apparatus and processes are presented to contact a dry, preferably high purity inert gas with a chemical composition in a pressure vessel, or a wetting composition, to form a wet inert gas, which is then used to pressurize the chemical composition out of the pressure vessel. No additional space is needed for an external humidifier. Since a very small amount of vapor is needed to form a wet inert gas, the composition of chemical composition will not be significantly affected.
