Process of blanketing with inert gas

Claim 2

A process for substantially eliminating oxygen from a shipping container while filling with a liquid comprising the steps of a. purging said shipping container with an inert gas by introducing said inert gas at the bottom of said container, pressurizing with said gas to about at least 10 psig, releasing said pressure, b. repeating said pressurizing and releasing steps for a plurality of times, c. introducing said liquid while maintaining flow of inert gas until said container is filled, and d. closing said container securely.

Claim 3

The process of claim 1 wherein said inert gas is selected from the group consisting of helium, neon, argon, nitrogen, carbon dioxide, methane, ethane, propane, butane and chlorofluorohydrocarbons.

Claim 4

The process of claim 2 wherein said gas is nitrogen.

Claim 5

The process of claim 3 wherein said liquid is nitromethane.

Claim 6

The process of claim 1 wherein said pressurizing and release is repeated twice.

Claim 7

The process of claim 1 wherein said pressurizing and release is repeated three times.

Claim 8

The process of claim 1 wherein said liquid and said gas are introduced at the bottom of said container.

Claim 9

The process of claim 1 wherein said gas is introduced under the top of said liquid.

Claim 10

A process for substantially eliminating dissolved oxygen from a liquid and from a shipping container therefor comprising the steps of a. purging a storage tank for storing said liquid with said inert gas to provide an atmosphere containing less than 1% oxygen, b. purging said liquid with said gas, c. filling said storage tank with said liquid while maintaining said inert gas atmosphere, d. pressurizing said tank filled with said liquid to from about 4 to about 7 psig, e. purging said shipping container with said inert gas by introducing said inert gas, pressurizing with said gas to about at least 10 psig, releasing said pressure, f. repeating said pressurizing and releasing steps for a plurality of times, g. introducing said liquid at bottom of said container while maintaining flow of inert gas until said container is filled, and h. sealing said container.

Claim 11

A process for substantially eliminating dissolved oxygen from a liquid and from a shipping container therefor comprising the steps of a. purging a storage tank for storing said liquid with said inert gas to provide an atmosphere containing less than 1% oxygen, b. purging said liquid with said gas, c. filling said storage tank with said liquid while maintaining said inert gas atmosphere, d. pressurizing said tank filled with said liquid to from about 4 to about 7 psig, e. purging said shipping container with said inert gas by introducing said inert gas, pressurizing with said gas to about at least 10 psig, releasing said pressure, f. repeating said pressurizing and releasing steps for a plurality of times, g. introducing said liquid at bottom of said container while maintaining flow of inert gas until said container is filled, and h. sealing said container.
