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

Patent number: 10357754Abstract: Oxidative dehydrogenation of paraffins to olefins provides a lower energy route to produce olefins. Oxidative dehydrogenation processes may be integrated with a number of processes in a chemical plant such as polymerization processes, manufacture of glycols, and carboxylic acids and esters. Additionally, oxidative dehydrogenation processes can be integrated with the back end separation process of a conventional steam cracker to increase capacity at reduced cost.Type: GrantFiled: April 26, 2018Date of Patent: July 23, 2019Assignee: NOVA Chemicals (International) S.A.Inventors: Vasily Simanzhenkov, Leonid Modestovich Kustov, Aleksey Victorovich Kucherov, Elena Dmitrievna Finashina, Xiaoliang Gao, Edward Christopher Foy, Claire Jeannine Ennis

Patent number: 10022699Abstract: The present invention provides low profile, thick (“stubby”) longitudinal fins having a cross section which is a parallelogram, trapezoid or a triangle extending from 10% to 100% of a coil pass and comprising from 3 to 45 weight % of a coil in a radiant section of a furnace for thermally cracking one or more of paraffins and naphtha. The fins provide an additional surface through which heat may be transferred to the coil making the coil more efficient reducing greenhouse emissions.Type: GrantFiled: February 8, 2018Date of Patent: July 17, 2018Assignee: NOVA Chemicals (International) S.A.Inventors: Grazyna Petela, Leslie Wilfred Benum, Edward Christopher Foy

Patent number: 10000706Abstract: Some embodiments of the present invention provide components for a serpentine fluid reactor which is optimized for one or more objective functions of interest such as pressure drop, erosion rate, fouling, coke deposition and operating costs. The components are designed by computer modeling the components individually and collectively in which the cross section of flow path is substantially circular under industrial conditions to validate the model design and its operation. Then iteratively the component designs are deformed and the operation of the deformed part(s) 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: October 6, 2016Date of Patent: June 19, 2018Assignee: NOVA Chemicals (International) S.A.Inventors: Eric Clavelle, Edgar Yajure, Leslie Wilfred Benum, Edward Christopher Foy, David Eisenhawer

Patent number: 9630893Abstract: In the operation of an oxidative dehydrogenation (ODH) process, it is desirable to remove oxygen in the product stream for a number of reasons, including to reduce oxidation of the product. This may be achieved by having several pre-reactors upstream of the main reactor having a catalyst system containing labile oxygen. The feed passes through one or more reactors saturated with labile oxygen. When the labile oxygen is consumed through a valve system, the pre-reactor accepts product from the main reactor and complexes reactive oxygen in the product stream until the catalyst system is saturated with labile oxygen. Then the reactor becomes a pre-reactor and another pre-reactor becomes a scavenger.Type: GrantFiled: December 6, 2016Date of Patent: April 25, 2017Assignee: NOVA Chemicals (International) S.A.Inventors: Vasily Simanzhenkov, Xiaoliang Gao, Edward Christopher Foy, Leonid Modestovich Kustov, Aleksey Victorovich Kucherov, Elena Dmitrievna Finashina
