International Classification:

B01D 19/00

US Classification:

95241, 423210, 222 3

Abstract:

This invention relates generally to an improvement in low pressure storage and dispensing systems for the selective storing of gases having Lewis acidity or basicity, and the subsequent dispensing of said gases at pressures, e. g. , generally below 5 psig and typically below atmospheric pressure, by modest heating, pressure reduction or both. The improvement resides in storing the gases in a reversibly reacted state within a reactive liquid having opposing Lewis basicity or acidity.

Abstract:

A mixture and method for the storage and delivery of at least one gas are disclosed herein. In one aspect, there is provided a mixture for the storage and delivery of at least one gas comprising: an ionic liquid comprising an anion and a cation; and at least one gas that is disposed within and is reversibly chemically reacted with the ionic liquid. In another aspect, there is provided a method for delivering at least one gas from a mixture comprising an ionic liquid and at least one gas comprising: reacting the at least one gas and the ionic liquid to provide the mixture and separating the at least one gas from the mixture wherein the at least one gas after the separating step is substantially the same as the at least one gas prior to the reacting step.

Abstract:

The invention relates to an improvement in apparatus and process for the formation of a complex of Lewis acidic or Lewis basic gases in a reactive liquid of opposite character and for the breaking (fragmentation) of said complex associated with the recovery of the Lewis gas therefrom. The improvement resides in forming finely divided droplets of reactive liquid and controlling the temperature, pressure and concentration of said Lewis gas of opposite character to provide for (a) the formation of said complex between said gas and reactive liquid or (b) the breaking of said complex and the recovery of the atomized droplets of reactive liquid.
