Publication number: 20220251977Abstract: In a fossil fuel waste incineration or plasma gasification process, waste heat generated by combustion of waste is captured by a heat transfer fluid and conveyed to an Organic Rankine Cycle (ORC) for energy recovery. In the case of a fossil fuel-fired waste incineration system, the heat transfer fluid captures waste heat from a double-walled combustion chamber, a heat exchanger being used to cool the hot process exhaust (gas cooler). In the case of a plasma waste gasification system, the heat transfer fluid captures waste heat from a plasma torch, a gasification chamber and combustion chamber cooling jackets as well as any other high-temperature components requiring cooling, and then a heat exchanger used to cool the hot process exhaust (gas cooler). The heat exchanger may take on several configurations, including plate or shell and tube configurations.Type: ApplicationFiled: November 15, 2021Publication date: August 11, 2022Inventors: Jason Robert TAVARES, Pierre CARABIN

Patent number: 10174424Abstract: Methods for producing coatings on substrates are provided. These methods comprise the steps of introducing the substrate in a photo-initiated chemical vapor deposition reactor, introducing a gas precursor in the reactor, irradiating said gas precursor with UV radiation at a given wavelength, thereby at least partly photodissociating the gas precursor, until the coating is formed. In one method, the gas precursor is a mixture comprising carbon monoxide and hydrogen. In another method, the pressure in the react or is between about 0.75 and 1.25 atm and the gas precursor has an absorption cross section of about 5×10?16 cm2/molecule or less at said given wavelength. In another aspect, the substrate is ash.Type: GrantFiled: April 17, 2014Date of Patent: January 8, 2019Assignee: Polyvalor, Limited PartnershipInventors: Jason Robert Tavares, Christopher Alex Dorval Dion

Patent number: 8546318Abstract: An aqueous composition comprising surfactant, water, and a suspending agent comprising microfibrous cellulose that is characterized by a particle size distribution of the microfibrous cellulose that provides for increased structuring of the composition to suspend material.Type: GrantFiled: November 4, 2010Date of Patent: October 1, 2013Assignee: Colgate-Palmolive CompanyInventors: Robert D'Ambrogio, Deborah Ann Peru, Joan Ethel Gambogi, Kevin Mark Kinscherf, Dipak Patel, Robert Tavares

Patent number: 8541355Abstract: A process that degasses a structured surfactant composition that comprises at least one surfactant, water, and at least one suspending agent chosen from polysaccharides, gums, and celluloses. By degassing the composition, the suspending agent can form a structured system. Gas, such as air bubbles, disrupts the formation of the structuring system, which reduces the ability of the composition to suspend materials.Type: GrantFiled: November 4, 2010Date of Patent: September 24, 2013Assignee: Colgate-Palmolive CompanyInventors: Melissa Marie Fleckenstein, Deborah Ann Peru, Kevin Mark Kinscherf, Robert Tavares, Cynthia Murphy, Dipak Patel, John Pettinari, Robert D'Ambrogio, Jodie Berta, Andrei Potanin
