Abstract:
In a cryogenic plant utilizing a liquid sparged into a cold vapor in heat exchange relationship with hotter vapor, variations in the load in terms of the volume of hot vapor are compensated for by a stepwise complete closing of a uniformly-spaced-apart fraction of the cold vapor passageways.
Abstract:
In order to obtain uniform mixing of materials in an agitated vessel, temperature measurements are made at two regions of the vessel spaced from one another. The amount of agitation imparted to the vessel is adjusted until the two measured temperatures are the same.
Abstract:
A heat exchanger has the tube sections supported by one or more units comprising a cylinder section surrounding the bundle of tube sections and having rods forming a rod baffle attached to each of its two opposing faces. In another embodiment, the tube sections are surrounded along a substantial porton of their length by a shroud cylinder having a plurality of rod baffles attached thereto. The shroud cylinder can be composed of a plurality of cylinder sections having recesses in their opposing faces so that abutting faces of adjacent shroud cylinder sections have facing pairs of recesses which correspond in shape essentially to the shape of the end of the rods of a rod baffle.

Abstract:
A plurality of parallel tubes in the form of at least a first plurality of parallel tube rows and a second plurality of parallel tube rows are supported by a baffle comprising an outer ring capable of surrounding the tubes and a plurality of parallel rods which form a plurality of parallel chords with the outer ring wherein the rods are capable of passing in the spaces between the tubes forming adjacent parallel tube rows of one plurality of parallel tube rows and wherein the number of rods in the baffle is substantially less than the total number of rods which could be positioned in the spaces between the tube rows in the plurality of parallel tube rows.
Abstract:
The tubes in a U-tube bundle are supported by rod baffles characterized by inner and outer arcuate rod support members. Methods and apparatus for assembling the components of the heat exchanger are also provided.
