The CatMax Reactor Internals are tapered high strength scallops that effectively distribute the inlet vapor across the catalyst bed. This allows a more constant gas velocity down through the scallop and a more even distribution across the axial portion of the catalyst bed. For revamp units, this tapered design allows greater catalyst volume

The reforming reactions take place via fixed chloride-based catalyst beds or continuous regeneration catalyst beds in radial flow reactors (catalytic reforming reactors), inside which scallops, which distribute the gas radially, and centerpipes, which collect the gas after the reaction, are installed.

Costacurta S.p.A.-VICO manufactures Reactor Internals to produce methanol, urea, ammonia, and for hydrocracking, hydrotreating and catalytic reforming processes.

Because the coke barrier has been addressed, the size of a catalytic reforming units has increased, substantially improving economies of scale for catalytic reforming. Several CCR Platforming units now are operating at feed rates exceeding 100,000 barrels per day.

The CCR Platforming process efficiently converts paraffins and naphthenes to aromatics with as little ring opening or cracking as possible. Figure 2 illustrates the key reactions. UOP has made great advances over the past two decades combining improved catalyst formulations with lower operating pressures that improve yields in the key reactions.

scallops. Called the OptiMiser system, it maintains a uniform bed thickness in order to make maximum use of the bed. Among the many advantages of OptiMiser scallops: • Install easily • Create high flow capacity • Make more effective use of catalyst than conventional scallops • Adapt to all size vessels • Stronger than conventional ...

Conduits for a radial flow reactor to provide fluid/solid contacting are improved structurally in terms of possessing good flexibility and a high resistance to vertical buckling when subjected to...

Vee-Wire scallop arrangement has a much higher total open area than a single large outer basket or perforated sheet scallops of the same size. This increased open area translates directly into reduced pressure drop and enhanced process efficiency. Standard Johnson screen scallops are available in any width or length, and in a wide variety of ...

With a fan-shaped cross-section, these scallops safeguard the reactor's inner wall, ensuring efficient catalyst distribution and protecting against deformation during temperature spikes and pressure variations.

Application: Continuous Catalytic reforming (CCR) unit. Design based on your application. The cover deck closes the gap between the internal screen component and the scallop. The flow direction could be outward or inward. Scallops are typically installed through the vessel's top manhole, mounted on a support ring attached to the vessel wall.
