Abstract
Abstract In a chemical installation having a group of tubular elements through which fluid from a common source circulates in varied flows in accordance with a given pattern, all of the tubular elements are mounted on identical feet that are each enclosed in a housing which is provided with a liquid inlet opening through which the liquid from the common source flows to the bottom entry end of the associated tubular element. Provided between the entry end of each tubular element and its associated liquid inlet opening is at least one annular constriction through which the liquid passes in its flow to such entry end. The different flows of liquid in the group of tubular elements are established by varying the number of the constrictions and/or their crosssections, and/or the locations of the liquid inlet openings.
