Support Grids manufactured from precision-engineered wedge wire screens play a critical role in hydroprocessing reactors, including hydrotreating and hydrocracking units. These grids are installed at the bottom of fixed-bed reactors to support catalyst beds, ensure uniform fluid distribution, and allow unrestricted passage of hydrogen and hydrocarbons under severe operating conditions.
Apollo Screens’ wedge wire support grids are designed to deliver exceptional mechanical strength, high open area, and long-term reliability in high-pressure, high-temperature refinery environments.
In hydroprocessing reactors, the support grid performs multiple critical functions:
Wedge wire construction ensures precise slot control and consistent performance throughout the reactor lifecycle.
Key Features
Typical Applications
To meet refinery and licensor specifications, support grids are available in:
Material selection is based on operating temperature, pressure, hydrogen partial pressure, and corrosion potential.
