  • Patent number: 11879693
    Abstract: Provided herein are components for a fluid network, specifically a U bend structure connected to at least two pipes which is modified for one or more objective functions of interest such as pressure drop, erosion rate, fouling, coke deposition and operating costs. The U bend structure is so designed to have a specific ARQ between 1.0 to 1.02 for 5% of the flow passage from the inlet and from the outlet, and an ARQ from 1.02 to 1.15 over the remaining 90% of the flow passage through an Rb/D ratio being greater than 1 and less than 4.

  • Patent number: 11828405
    Abstract: 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.

  • Patent number: 10000706
    Abstract: 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.
