Deemulsifiers for oil-based emulsions
Patent
·
OSTI ID:6148813
The treatment is described of emulsions encountered in the production, handling, and refining of crude mineral oil, for the purpose of separating the oil from water, brine, and aqueous acidic material. It has now been found that emulsions of petroleum and brine or acid can be broken through the agency of certain propylene oxide adducts of fatty alcohol phosphates. The compositions of this type show unusual utility in breaking emulsions of petroleum and hydrochloric acid of various strengths. (3 claims)
