Abstract
Methods and compositions for breaking foams, emulsions, or any combination thereof. The foam, emulsion, or any combination is contacted with a breaking composition. The breaking composition comprises a sulfosuccinate and a solvent. The solvent has an octanol/water partition coefficient ([P]) at 25°. The log of the partition coefficient at 25° (log [P]) is from 0.1 to 5.
Claims19
A method of breaking a foam, emulsion, or any combination thereof, the method comprising:
- contacting the foam, emulsion, or any combination thereof with a breaking composition, wherein the breaking composition comprises a sulfosuccinate and a solvent;
- wherein the solvent has an octanol/water partition coefficient ([P]) at 25°, and wherein the log of the partition coefficient at 25° (log [P]) is from 0.1 to 5;
- wherein the sulfosuccinate is present in an amount sufficient to reduce foam by at least 50%.
A breaking composition comprising a sulfosuccinate and a solvent, wherein the solvent has an octanol/water partition coefficient ([P]) at 25°, and wherein the log of the partition coefficient at 25° (log [P]) is from 0.1 to 5;
- wherein the sulfosuccinate is present in an amount sufficient to reduce foam by at least 50%.
