Provided herein are components for a fluid network modified for one or more objective functions of interest such as pressure drop, erosion rate, fouling, coke deposition and operating costs.

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.

An apparatus for the separation or liquefaction of a gas at cryogenic temperatures which comprises an isolated chamber comprises at least one front distillation column operating at cryogenic temperatures and also a pipe for transferring fluid coming from or going to the column, the pipe having a diameter D comprising a bend for changing the direction of flow of the fluid, with profiled deflector vanes placed inside the bend, with their concavity towards the centre of the bend forming a plurality of ducts.

An adjustable duct start collar may include a base with a flange on a first end of the base and a plurality of tabs on a second end of the base. The base may be constructed of a material of substantially uniform thickness and include at least two slots in the base. The first of the slots may be positioned substantially parallel to a second of the at least two slots. Each of the slots of the at least two slots being able to independently receive the flange, whereby when the base is curved into a cylindrical shape with the flange positioned in the first of at least two slots, the curved base will form a cylindrical shape with a first diameter and when the flange is positioned in the second of the at least two slots, the curved base will form a cylindrical shape with a second diameter.

An intake device for a pump includes an inlet section extending in a first direction for guiding a fluid, an outlet section for delivering the fluid to an inlet of the pump, the outlet section extending in a second direction perpendicular to the first direction, and a diverting section for diverting the fluid from the first to the second direction, the diverting section connecting the inlet and outlet sections, and having a bottom wall opposing the an outlet opening and a back wall opposing an inlet opening, the inlet section tapering towards the diverting section to decrease a cross sectional area of the inlet section, the diverting section includes a splitter member arranged on the bottom wall that tapers in the second direction towards the outlet opening, and the outlet section includes an essentially bell shaped reducing part for decreasing a cross sectional area of the outlet section.

A round metal pipe 1 including a bend portion 10 is configured such that on an axial direction cross-section of the bend portion 10, an outer half portion 11b of a peripheral wall portion 11 of the bend portion 10 has an outwardly projecting, non-circular arc shape in which a central portion in a y direction, which is orthogonal to a bend radius direction x of the bend portion 10, forms an outermost peripheral portion 13, and a distance Lb from respective intermediate portions 15 between the outermost peripheral portion 13 and a pair of proximal end portions 14 of the outer half portion 11b to a pipe center O is shorter than a distance La from the outermost peripheral portion 13 to the pipe center O. Thus, advantages such as suppressing reductions in the sectional area and minimum inside width of the bend portion 10 and reducing flow path resistance can be obtained, and the round metal pipe 1 can be manufactured easily and appropriately.
