Serpentine fluid reactor components

摘要

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.

1. A pipe for a fluid serpentine reactor said pipe having individually or in co-operative arrangement an internal flow passage having a continuously smooth and differentiable perimeter and centerline and a smoothly varying cross-section along the flow passage such that in the about 5% of the flow passage from the inlet and the outlet of each pipe the ARQ is from about 1.0 to about 1.02 and over the remaining about 90% of the length of the flow passage not less than about 5% of the flow passage has an ARQ is from about 1.02 to about 1.15, where ARQ is defined as the ratio of aspect ratio (AR) to isoperimetric quotient (Q) of a section or segment of the flow passage perpendicular to the direction of flow (AR/Q) and further where AR=Long/Short and Q=4πA/L2 where A is area of a cross section of the flow path and L is the perimeter.
