Abstract
In large catalytic reaction apparatus where a fluid is catalytically treated as it flows through tubes, the apparatus is divided into a number of modular units which are assembled at a production location, shipped to a construction site and joined together to form the apparatus at the construction site. Each modular unit has a similar shape and has a sector-like shape in section extending transversely of the axial direction of the tubes. Each modular unit includes a plurality of tubes extending between a pair of sector-like shaped tube sheet sections with side walls laterally enclosing the tubes and forming, in combination with the tube sheet sections, a sealed modular unit which is capable of being tested at the production location before being shipped to the construction site.
