Johnson Screens designs and manufactures a wide range of vessel internals for media retention. Among these innovative products is a line of internals used in downflow or upflow systems 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, our support grid and distributor tray systems are widely used in hydrotreaters, desulfurizes, hydrocrackers, molecular sieves, sand filters, gas sweeteners, and other absorption systems.
Watch the Shaped Support Grid in Action
Johnson Screens’ Shaped Support Grid is installed into the bottom head of hydroprocessing or gas dehydration vessels. This allows for increased media volume, increased run time, improved gas and liquid flow distribution, and an overall more efficient process.
