Inert top layer media
Catalyst top layer media
All inert top gradings are developed to replace inert ceramic balls and alumina balls at the top of catalytic reactors, by increasing distribution properties and void fractions to extend cycle length of the units. The larger void fraction and different shapes allow better resistance against particulate deposition (solids such as rust, gum, coke, etc.) or top bed crust formation.
- Naphtha Hydrotreating (NHT)
- Distillate Hydrocracker (DHC)
- Hydrodesulfurization (DHS)
- Hydrodenitrogenation (HDN)
- Improve flow distribution
- Reduce pressure drop built-up
- Better resistance against particulate deposition
- Protection at refinery upsets
- High void fraction
- High mechanical strength
- Good initial distribution
- high holding capacity for scale and large particulate
- Designed to trap fine particulates from the reactor feed
- Different mesh sizes to trap different particulates
- Increase the cycle length in terms of pressure drop built-up compared to other traps
- In case of sub-5 micron fines, smaller and more dense discs can be provided
- Suitable to be used in conjunction with other top layers and catalyst
- We offer to help in selecting the required type based on void fraction for optimum operation
All above listed inert top grading materials are also supplied in other materials like high purity inert alumina.
