Abstract

1361421 Tubular heat exchanger elements; revaporizing gases L'AIR LIQUIDE SOC ANON POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDE 16 July 1971 [16 July 1970] 33625/71 Headings F4S and F4P A tubular heat exchanger element used for vaporizing a liquefied gas includes a centrally disposed core member 2 which together with the internal wall surface of the tube 1 defines a fluid passage whose cross-section decreases in the direction of fluid flow therethrough. The core member may comprise two or more (see Fig. 1) cylindrical sections having differing diameters or may comprise a single section of frustoconical shape (see Fig. 4). The tubular element is provided with both internal fins 3 and external fins 9. In use the liquefied gas to be vaporized, e.g. liquid methane or nitrogen, passes upwardly through the space between the core member and the internal wall of the tube and is heated indirectly by a liquid, e.g. water, flowing downwardly as a film over the external surface of the element. The surface of the core member may be associated with a variable pitch helix, the pitch being greater in the lower 'cold' zone than in the upper 'hot' zone of the element.
