Patent number: 11885489Abstract: The present disclosure seeks to provide a metallic burner tile for use in industrial processes such as cracking. The tile is substantially metallic (e.g. more than 80%) with the balance being ceramic coating on surfaces exposed to high temperature. The tile is lighter and more durable than the current ceramic burners.Type: GrantFiled: February 3, 2022Date of Patent: January 30, 2024Assignee: NOVA Chemicals (International) S.A.Inventors: Jeffrey Stephen Crowe, Eric Clavelle, Leslie Wilfred Benum, Vasily Simanzhenkov, Lucas MacNeil Harding

Patent number: 11828405Abstract: The present invention provides a transfer line exchanger which is optimized for one or more objective functions of interest such as pressure drop, erosion rate, fouling, coke deposition and operating costs. The transfer line exchanger is designed by computer modeling a transfer line exchanger in which the cross section of flow path is substantially circular and modeling the operation of the transfer line under industrial conditions to validate the model design and its operation. Then iteratively the model design is deformed and the operation of the deformed part is modeled and compared to values obtained with other deformed models until the value of the objective function is optimized (e.g. at an extreme) or the change in the objective function is approaching zero.Type: GrantFiled: September 24, 2020Date of Patent: November 28, 2023Assignee: NOVA Chemicals (International) S.A.Inventors: Eric Clavelle, Edgar Yajure, Leslie Wilfred Benum, Edward Christopher Foy, David Eisenhawer

Publication number: 20210190435Abstract: If a cracked gas heat exchanger becomes damaged water may enter the transfer line causing it to rupture. This may be avoided using a heat exchanger having heat pipes to conduct heat from the cracked gas to a cooling device, typically a water cooler to generate steam. The latter (cooling device) is physical separated from the hot cracked gas stream. The heat pipes may be modified at the hot or cold end with fins, ribs, protuberances, pins and the like.Type: ApplicationFiled: January 18, 2017Publication date: June 24, 2021Applicant: NOVA Chemicals (International) S.A.Inventors: Leslie Wilfred Benum, Eric Clavelle, Kamal K Botros, Vasily Simanzhenkov, Hany Iskandar Farag, Michael Edward Koselek

Publication number: 20190309943Abstract: The present disclosure seeks to provide a method to design a metallic burner component for use in industrial processes such as cracking, reforming and steam generation for which the burner component is exposed to high furnace temperatures. The burner component comprises a series of cooling channels and internal baffling to direct the flow of one or more fuel and oxidant over the portions of the burner exposed to the high furnace temperatures. The present disclosure also provides the resulting burner.Type: ApplicationFiled: June 1, 2017Publication date: October 10, 2019Applicant: NOVA Chemicals (International) S.A.Inventors: Jeffrey Crowe, Eric Clavelle, Leslie Wilfred Benum, Vasily Simanzhenkov
