Abstract
This invention relates to the use of hydrocarbon polymers or copolymers in conjunction with demulsifiers in demulsification. The use of said hydrocarbon polymers-demulsifier combination is more effective in demulsification than is achieved by the use of the demulsifier alone. The process is particularly effective in desalting oils.
