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.

Abstract: Disclosed herein are methods for reducing fouling caused by process water present within a water recycling loop of a pyrolysis plant. The process water includes water, a pygas, and in some cases pygas byproducts. Fouling is caused by phase separation and accumulation of materials from the process water on equipment surfaces. The method includes applying a total of about 5 ppm to 500 ppm of one or more antifouling polymers to the process water to form a treated process water. The one or more antifouling polymers are selected from the group consisting of copolymers of unsaturated fatty acids, primary diamines, and acrylic acid; copolymers of methacrylamidopropyl trimethylammonium chloride with acrylic acid and/or acrylamide; copolymers of ethylene glycol and propylene glycol; and blends of two or more thereof.

Abstract: Disclosed are antioxidants used in compositions and methods to stabilize synthetic feedstock derived from plastic. Some methods disclosed herein include adding an antioxidant composition to a plastic-derived synthetic feedstock composition. Some methods disclosed herein include heating plastic under substantially oxygen free conditions at a temperature of from about 400° C. to about 800° C. to produce a pyrolysis effluent, distilling the pyrolysis effluent, recovering the synthetic feedstock, and adding a stabilizer to the synthetic feedstock to reduce contamination. The disclosure also provides compositions including a synthetic feedstock derived from plastic and an antioxidant.
