Patent number: 11174439Abstract: 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.Type: GrantFiled: August 23, 2017Date of Patent: November 16, 2021Assignee: Ecolab USA Inc.Inventors: Jerome Vachon, Anthoni van Zijl, Fabrice Cuoq, Steven Leen, Carlo Geijselaers, Andrew R.

Patent number: 10604431Abstract: 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.Type: GrantFiled: December 27, 2016Date of Patent: March 31, 2020Assignee: Ecolab USA Inc.Inventors: Steven Leen, Fabrice Cuoq, Anthoni van Zijl, Jerome Vachon, Russell P.
