Distributor Trays
Distributor trays for reactors fall into 3 types:
| Sieve Type |
| Bubble Cap Type |
| Distribution Tube Type |
The most prominent is the distribution tube type with each Process Licensor having their own distinct features.
The trays are designed for two phase co-current flow and ensure good vapour and liquid distribution so that the entire bed of catalyst is used effectively.

Remixing & Quench Assemblies
A remixing & quench assembly is used between the catalyst beds to ensure efficient heat and mass transfer between the cold quench gas and the vapour & liquid effluent from the upper catalyst bed. This results in efficient heat and mass transfer with uniform composition and an even temperature profile in the bottom (lower) catalyst bed.

Outlet Collectors (Baskets)
An outlet collector (basket) ensures even flow distribution in the bottom bed to achieve optimum catalyst utilisation and prevents escape of the catalyst.
The collectors can be wedge wire type or perforated type c/w mesh screen.
