Liquid Gas Contact Scrubber

We couldn’t find a gas scrubber that did everything we wanted it to – so we built our own.

FEG’s patent-pending Liquid Gas Contact Scrubber (LGC) was designed to solve tricky food odour control issues.

Odour issues are usually difficult to solve as they involve a mix of sticky particulate, multiple compounds, temperature, and variable processes. The FEG Liquid Gas Contact Scrubber scrubs the oil mist and the odour/acridity emissions, removing odour.

Our practical and effective solution to odour control delivers compliance with the requirements of BAT (Best Available Technique) and can be controlled via a simple-to-use interface with remote data logging functionality.

How does a gas scrubber work?

In the simplest terms, a gas scrubber uses a scrubbing solution (such as water) to remove unwanted particulates from a gas stream.

The type of gas scrubber required depends on the particulate. For example, water-soluble gases such as hydrochloric acid (HCI) or ammonia (NH3) can be removed using a wet scrubber. Wet scrubbers work by accelerating the gas stream into high density spray which separates the particles. In contrast, a dry gas scrubber uses very little or no moisture and instead works by introducing a gas sorbent (alkaline) material into the gas stream.
