Abstract: Disclosed herein are methods for reducing fouling caused by process water present within a water recycling loop of a pyrolysis plant. 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 total of a first polymerization inhibitor and second polymerization inhibitor to the process water to form a treated process water, wherein the first polymerization inhibitor has a pygas-water partition coefficient of about 0.0001 to 9 and the second polymerization inhibitor has a pygas-water partition coefficient of about 1000 to 50,000.

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 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: Methods to increase the efficiency and throughput of hydrocarbon stream cracking by inhibiting the formation of, or resolving an emulsion, in an ethylene production quench water system. The method includes contacting a non-alkoxylated branched or linear polyethylenimine (PEI) with a quench water composition from the quench water system under conditions suitable to prevent the formation of an emulsion or to resolve the quench water composition into two immiscible phases.
