Internal for Radial Flow Reactor
Radial flow systems increase contact efficiency between the process stream and catalyst bed. Because of this, vessel size can be dramatically reduced. Given equal vessel diameters, for example, a 20 ft tall a radial flow system can handle the same flow as a 40 ft long horizontal bed. Processors can save on vessel capital cost and the equipment operating costs needed to push the flow through it.
Some processes achieve the highest production rate of desired product by operating with very low pressure drops across the screen and bed. Johnson Screens is the premier manufacturer of screen set requiring tight annulus tolerances.

Internal for Down Flow Reactor
Johnson Screens designs and manufactures a wide range of vessel internals for media retention. Amongst these innovative products is a line of internals used in down-flow or up-flow system to retain the often-costly media and to provide a collection area for the process flow across the entire vessel diameter or length. Because of their strength, durability and flow characteristics, support grid and distributor tray systems are widely used in hydrotreaters, desulfurisers, hydrocrackers, molecular selves, sand filters, gas sweeteners and other absorption systems.
