Process for pumping gases using a chemically reactive aerosol

Claim 2

A process for pumping a selected gaseous material to remove it from a container which comprises: (a) providing a chosen highly reactive substance in solid form; (b) heating said solid highly reactive substance at a predetermined elevated temperature sufficient to change said solid to a liquid; (c) causing said liquid to flow through a means for dispersing said liquid into aerosol particles; and (d) mixing said aerosol particles with said gaseous material in a reaction chamber to cause a chemical reaction therebetween of the type sufficient to form a solid, nonvolatile reaction product and to thereby generate a partial vacuum in said chamber and provide the pumping of said gaseous material from said container.

Claim 3

The process as set forth in claim 1 wherein said liquid is caused to flow through said dispersing means by applying to said liquid a chosen inert gas under predetermined pressure.

Claim 4

The process as set forth in claim 2 wherein said inert gas is chosen from the group consisting of argon, neon, helium, xenon, and krypton.

Claim 5

The process as set forth in claim 1 wherein the selected gaseous material is removed to thereby produce a pressure of 1 torr or more in the original container of said gaseous material.

Claim 6

The process defined in claim 1 wherein said highly reactive substance is selected from the group consisting of lithium, sodium, potassium, calcium, mixtures thereof, and a substance which has a high chemical affinity for said gaseous material and forms solid, non-volatile products by reaction with said gaseous material.

Claim 7

The process defined in claim 1 wherein said gaseous material is selected from the group consisting of nitrogen; oxygen; a mixture comprising nitrogen, hydrogen, deuterium, and hydrogen flouride; and a gas which is capable of reacting with said reactive substance to form a solid, non-volatile product.

Claim 8

A process for pumping certain exhaust gases from a container therefor by converting said gases into solids suitable for solution into and transport by a selected liquid transporting medium, which comprises: (a) providing a chosen highly reactive substance in liquid form, said reactive substance being selected from the group consisting of lithium, sodium, potassium, calcium, mixtures thereof, and a substance which has a high chemical affinity for said exhaust gases and forms solid, nonvolatile products by reaction with said exhaust gases; (b) causing said liquid to flow through a means for dispersing said liquid into aerosol particles by applying to said liquid a chosen inert gas under predetermined pressure; and (c) mixing said exhaust gases selected from the group consisting of nitrogen; oxygen; a mixture comprising nitrogen, hydrogen, deuterium, and hydrogen fluoride; and a gas which is capable of reacting with said reactive substance to form a solid, nonvolatile product, with said particles in a reaction chamber to cause a chemical reaction between said particles and said gases, of the type sufficient to form a solid reaction product which deposits in a chosen location and to thereby generate a partial vacuum in said chamber.

Claim 9

A process for pumping certain exhaust gases from a container therefor by converting said gases into solids suitable for solution into and transport by a selected liquid transporting medium, which comprises: (a) providing a chosen highly reactive substance in liquid form, said reactive substance being selected from the group consisting of lithium, sodium, potassium, calcium, mixtures thereof, and a substance which has a high chemical affinity for said exhaust gases and forms solid, nonvolatile products by reaction with said exhaust gases; (b) causing said liquid to flow through a means for dispersing said liquid into aerosol particles by applying to said liquid a chosen inert gas under predetermined pressure; and (c) mixing said exhaust gases selected from the group consisting of nitrogen; oxygen; a mixture comprising nitrogen, hydrogen, deuterium, and hydrogen fluoride; and a gas which is capable of reacting with said reactive substance to form a solid, nonvolatile product, with said particles in a reaction chamber to cause a chemical reaction between said particles and said gases, of the type sufficient to form a solid reaction product which deposits in a chosen location and to thereby generate a partial vacuum in said chamber.

Claim 10

The process as set forth in claim 7 wherein said inert gas is selected from the group consisting of argon, neon, helium, xenon, and krypton.
