Abstract:
1. A device for injecting gas into vertical reactor tubes in a chemical reactor, wherein each vertical reactor tube has an inside diameter and extends downwardly from a horizontal upper tube sheet to a horizontal lower tube sheet, and wherein there is a horizontal floor below the lower tube sheet, comprising: a base; a plurality of rollers mounted on said base so as to support said base on the horizontal floor and to allow said base to move along the horizontal floor; a set of telescoping legs extending upwardly from said base; a support frame supported on said telescoping legs and movable from a lowered position to a raised position; a plurality of upwardly directed injector tubes mounted on said support frame for injecting gas into reactor tubes located above said rollers, with fixed spacings between the injector tubes; wherein said support frame is mounted on a track which allows for restricted movement of said support frame along a front-to-back horizontal axis relative to said base; and wherein said rollers define a support footprint for said base, and the injector tubes of the tube test device lie within an imaginary vertical column projecting upwardly from said support footprint, in order to avoid creating forces tending to tip over said base.
