Our Terrace Wall™ reformer is well-suited to a high degree of shop modularisation.
The entire radiant section can be supplied in modules, complete with casing, structure, lining, burners, inlet and outlet pigtails, catalyst tubes, inlet and outlet manifolds. High-alloy welding is performed and tested in a controlled shop environment, eliminating costly field welding, rework and testing. The only field welds are the inlet and outlet manifold girth welds that join modules together. Each radiant module becomes its own perfect shipping container, designed easily for overland transportation.
Convection sections and stack assemblies are supplied in maximum shipping sizes advised by our logistics experts. Other components and equipment are supplied in the maximum sizes permitted by design or shipping requirements.
Catalyst tubes are now supplied with vertical outlet pigtails to minimise the pigtail-to-manifold stresses, virtually eliminating pigtail failures. A flexible inlet pigtail provides the vertical expansion required to reduce outlet stresses. Simple counterweight systems are used to support not only the catalyst tubes but also the inlet manifold. These require no maintenance or adjustment in operation.
The process gas boiler, complete with internal bypass controls, is located beneath the radiant cell and close-coupled to the outlet manifold, virtually eliminating the transfer line issues prevalent in top-fired designs.
Outboard burner mounting provides ease of access and space for maintenance. Sight doors are conveniently located at the burner levels to perform tube monitoring and burner tuning.
