Other column internals
Gas distributors
Gas distributors distribute the incoming gas flow evenly across the cross-sectional area of a column.

Random packings
Designed to optimise the contact surface area between gas and liquid, with lowest possible pressure drop.
View products
Structured packings
Used in processes with low liquid load, high gas flow and low pressure drop requirements.

Droplet separators
Droplet separators and demisters are used to remove liquid from the gas stream, minimising the amount of liquid entrained in the gas exiting the column.
