Patent ID: 7638058

Claim:
A method of packaging a process fluid for an end user that can be shipped, stored, handled and dispensed, comprising: providing a vessel containing an ionic liquid therein configured for selective dispensing of the process fluid therefrom; contacting the process fluid with said ionic liquid for take-up of the process fluid by said ionic liquid, wherein there is substantially no chemical change in said ionic liquid and the process fluid; shipping said vessel containing the process fluid to the end user wherein the contained process fluid becomes contaminated prior to being dispensed and the end user is able to dispense said process fluid from said vessel, separately from said ionic liquid and the contaminant, by controlling a temperature and/or a pressure gradient of said ionic liquid, wherein the process fluid is selected from the group consisting of: alcohols, aldehydes, amines, hydrocarbons, ammonia, aromatic hydrocarbons, arsenic pentafluoride, arsine, borane, boron trichloride, boron trifluoride, carbon disulfide, carbon monoxide, carbon sulfide, chlorine, diborane, dichlorosilane, digermane, dimethyl disulfide, dimethyl sulfide, disilane, ethers, ethylene oxide, fluorine, germane, germanium methoxide, germanium tetrafluoride, hafnium methylethylamide, hafnium t-butoxide, halogenated hydrocarbons, halogens, hexane, hydrogen, hydrogen cyanide, hydrogen halogenides, hydrogen selenide, hydrogen sulfide, ketones, mercaptans, nitric oxides, nitrogen, nitrogen trifluoride, organometallics, oxygenated halogenated hydrocarbons, phosgene, phosphorus trifluoride, silane, n-silane, pentakisdimethylamino tantalum, silicon tetrachloride, silicon tetrafluoride, stibine, styrene, sulfur dioxide, sulfur hexafluoride, sulfur tetrafluoride, tetramethylcyclotetrasiloxane, titanium diethylamide, titanium dimethylamide, trichlorosilane, trimethyl silane, tungsten hexafluoride, and mixtures thereof, and wherein the process fluid is a gas or a liquefied gas introduced into said vessel under pressure and/or the process fluid being introduced is a compressed or liquefied gas.
