Abstract
Abstract A method of breaking down oil emulsions comprising, in accordance with the invention, heating the oil emulsion to be broken down to a temperature of from 40° to 70°C, preferably from 60° to 65°C, and bubbling air at the rate of from 0.1 to 10 nm 3 per 1 m 3 of the emulsion (preferably from 1 to 4 nm 3 per 1 m 3 of the emulsion) through said heated oil emulsion until total breakdown thereof occurs as a result of oxidation of the natural oil emulsifiers contained therein.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
88 words
A method of breaking down oil emulsions, which comprises heating the oil emulsion to be broken to a temperature of from 40° to 70°C; bubbling air through said heated oil emulsion at the rate of from 0.1 to 10 nm 3 per 1 m 3 of the oil emulsion until total breakdown of the emulsion as a result of oxidation of the natural oil emulsifying agents contained therein; settling the mixture to provide for the separation of oil and water; and separating the oil from the water layer.
Claim 2
Independent Claim
88 words
A method of breaking down oil emulsions, which comprises heating the oil emulsion to be broken to a temperature of from 40° to 70°C; bubbling air through said heated oil emulsion at the rate of from 0.1 to 10 nm 3 per 1 m 3 of the oil emulsion until total breakdown of the emulsion as a result of oxidation of the natural oil emulsifying agents contained therein; settling the mixture to provide for the separation of oil and water; and separating the oil from the water layer.
Claim 3
Dependent Claim
21 words
A method as claimed in claim 1, whereby said oil emulsion is heated to a temperature of from 60° to 65°C.
Claim 4
Dependent Claim
32 words
A method as claimed in claim 1, whereby air is bubbled through the emulsion at the rate of from 1 to 4 nm 3 per 1 m 3 of the oil emulsion.
