  • Method to resolve emulsions formed during ethylene manufacture
    Patent number: 10047301
    Abstract: Disclosed herein are methods for resolving emulsions formed from oils present in quench waters of ethylene manufacturing operations. The methods include adding a cationic oligomer to the base of a water quench tower having an emulsion formed therein, and collecting a water phase therefrom. The water phase can be applied to a water recycling loop within the manufacturing facility.
