  • Oil emulsion removal and recovery of oil
    Patent number: 4082867
    Abstract: Oil emulsion is removed from the surfaces of articles by washing the articles with an aqueous solution of wash water and demulsifier, thereby forming a turbulent mixture of the wash water, the demulsifier and the oil emulsion. The demulsifier is effective in breaking the oil emulsion. The liberated oil is allowed to form a separate phase in the solution of wash water/demulsifier, and is removed therefrom in a quiescent stage. The aqueous solution of wash water and demulsifier having the oil removed therefrom is recycled to wash oil emulsion from other of said articles. The preferred demulsifiers are ammonium and alkali metal sulfates and bisulfates.
