OptiMiser Scallops

Johnson Screens has developed a screen system that combines the process efficiencies of an outer basket with the installation and maintenance advantages of standard scallops. The OptiMiser system maintains a uniform bed thickness in order to make maximum use of the bed.

Unique Selling Point

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.

Insights

Johnson Screens developed a patented screen system, called the OptiMiser® system that combines the process efficiencies of an outer basket with the installation and maintenance advantages of standard scallops. It maintains uniform bed thickness in order to make maximum use of the catalyst and optimise flow through the bed. 


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.
