Johnson Screens OptiMiser Scallops
Insights
Advantages include: Installs easily Creates high-flow capacity. Makes more effective use of catalyst than conventional scallops. Adapts to all size vessels. Stronger than conventional scallops. Creates a uniform thickness annulus for predictable process flow and pressure drop. Slots are as small as 0.25 mm / 0.010 in. and any size larger in increments of 0.025 mm / 0.001 in. Includes system sealing components and cover plate connections.
OptiMiser scallops can be fabricated to nearly any size, all with the following key features: Blank interval at screen top prevents “short-circuiting” of ¬ow if the catalyst bed settles. Longitudinal and horizontal plates seal spaces between screens. The space between the back of the screen and the vessel wall is also sealed.
Vertical slots and smooth Vee-Wire face prevent abrasion of catalyst beads as the bed moves vertically in operation. Rugged welded construction of the OptiMiser scallops creates high column strength. Expander rings are not required for maintaining scallop in position, which removes impediments to catalyst movement vertically along the face.
