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: 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
