Odour Control System Design

Odour control system design, build and installation services, delivered by our expert in-house team.

From consultation to full turnkey project delivery, our expertise in odour abatement is globally recognised. Clients such as Essentia Proteins and Whitby Seafoods trust our cradle-to-grave approach in designing, specifying, installing and maintaining their odour control system.

Our in-house team of chemical and mechanical engineers work seamlessly to develop integrated solutions to odour problems across multiple countries and sectors. 

The problem of industrial odour

Production processes sites such as food factories and chemical plants generate odours offensive to both workers and local communities. 

Odour is classed as a pollutant and consistent exposure to strong odour can bring complaints and harm brand reputation. Involvement of environmental health authorities can include production restrictions, fines and, at worst, closure notices.

Featured Project
Solving odour control in complex, high-temperature frying environment

A unique odour problem due to high frying temperatures and aggressive raw products meant that this client had received communication from Environmental Health after residential complaints had been upheld.   

As a full turnkey package we designed and installed a system including wet scrubbing, filtration and activated carbon. This dealt with the sticky particulate, fine sub-micron mist and adsorption of gas phase contaminants.  The project included roof works, support steelwork and access, PLC control and drainage.   

The odour problem was resolved for the client and we continue to service and maintain the solution.

Bespoke odour abatement systems, unique to each problem

Odour can be a complex problem to solve, with a range of solutions available depending on the root cause of the problem.
In our experience, odour issues are usually caused by a combination of sticky particulate, water and gas. Removal of all three requires a multi-faceted approach. At FEG, we won’t just install a scrubber and walk away. Instead, we’ll design and build bespoke odour control systems that remove all three in an order that works.

  • Odour control systems management planning
  • Feasibility & concept design
  • FEED & detailed engineering
  • Procurement and supplier management
  • Construction management & site installation
  • Commissioning, testing & verification
  • EPC contracts and management of  Directive 89/391/EEC duties*

*The Directive 89/391/EEC lays down minimum safety and health requirements for temporary or mobile construction sites i.e. any construction site at which building or civil engineering works are carried out and intends to prevent risks by establishing a chain of responsibility linking all the parties involved.  Each European country has its own guidelines for adherence to this directive.  Some examples can be found below.

Odour Control Technologies

Various compounds, generated by a wide range of processes, can cause offensive odours. Ammonia, amines, hydrogen sulphides, aldehydes, ketones, alcohols, mercaptans and volatile organic compounds (VOCs) are all known odour-generating contaminants, often requiring individual solutions for removal.

Our in-house team of chemical, electrical and mechanical engineers understand the right combination of odour abatement solutions to build a system that goes beyond your legal, safety and environmental requirements.

We can design and supply full odour control systems that incorporate all required pipework, pumps, chemical dosing and storage systems, extraction equipment, stacks and control panels. We work with wet scrubbers, dry scrubbers and carbon adsorption technologies among others.

The FEG Liquid Contact Gas (LCG) 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 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 both the oil mist and the odour/acridity emissions.

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.

EU Best Available Technique reference documents (BREFs) outline a range of steps that should be taken, wherever practicable, to meet operating conditions and emissions criteria when carrying out industrial activities. EU member states are required to consider these documents when determining Best Available Techniques (BAT).

The LGC features a flexible and modular multi-stage design, allowing us to tailor it to suit your requirements.

    • Fire barrier – accepted by insurance companies
    • Legionella control
    • Clean ducts after scrubber
    • Wet particulate scrubber
    • Fine filtration
    • Gas scrubbing – activated carbon
    • Chemical scrubbing – dosing system


    • HMI screen data
    • Data collection
    • Remote login support
    • Secure data transfer
    • Real time data
    • Immediate engineer support


Featured Project
Acridity issue in seafood frying factory

This seafood manufacturer had received complaints from local residents.  They needed a system that would remove the acrid odour generated from the high temperatures and oil mists within the production process. 

Our team carried out a full investigative process, including surveys and a pilot plant set-up. It was clear that traditional scrubbers would not have had the full functionality to deal with the particular combination of contaminants in the air flow. 

We therefore designed and commissioned a bespoke LGC system that could deal with the volumes, composition and variance in contaminants.  The acrid odour was resolved for our client and environmental health authorities satisfied with the solution.

Our expertise in odour control systems is unrivalled
