Gas distributors
Gas distributors distribute the incoming gas flow evenly across the cross-sectional area of a column.
With the right design, pressure loss can be minimised. To select the right type of gas distributor and the right material; gas volume, gas velocity, temperature, and gas composition are taken into account.
If required, CFD simulations of the incoming gas stream for a specific gas distributor can be provided.

Ensure optimal gas distribution in the column
A well-designed gas distributor distributes the incoming gas flow evenly across the cross-sectional area of the column with as low a pressure loss as possible.
Factors taken into account when designing a gas distributor for a specific process are:
- gas flow volume
- gas velocity
- temperature
- geometric design of the gas duct and tower
- gas composition and content
If required, CFD simulations of the incoming gas stream for a specific gas distributor can be provided.
