» VOC and Odour Control

VOC and Odour Control Specialists

Babcock Wanson have more than 150 years of experience of thermal engineering, there are thousands of efficient plants around the world, which are designed, serviced and maintained by our in-house engineering experts. In addition to standard products like boilers, thermal fluid heaters and air heaters, over 300 Thermal Oxidisers have been designed, fabricated and commissioned. Babcock Wanson is therefore in an unchallenged position to provide turnkey solutions to almost any problem concerning compliance with Environmental Permitting regulations such as VOC abatement, odour control, treatment of stationary diesel engine emissions and energy recovery.

A full in-house service is provided. 2 factories with full design and manufacturing facilities are backed up by a research centre. Erection and commissioning under the direction of our skilled engineers is backed up by local parts availability in the UK for quick despatch. Babcock Wanson service engineers are located throughout the UK and are dedicated to the servicing and long term maintenance of our plants.

Optimize Your Energy Production

Thermal Oxidation

Now regarded as the Best Available Control Technology for dealing with VOC abatement and odour control  issues for process air streams, thermal oxidation is now a fully automated process enabling successful compliance with environmental obligations.  With the correct design and control systems the oxidiser is a fully automated plant that needs almost no manpower and little maintenance. The engineering concept is to subject the Volatile Organic Compounds (VOCs) or other pollutants, to high temperatures for a minimum time. These conditions convert the contaminants to water, and carbon dioxide which can safely be discharged to atmosphere.

Recuperative Thermal Oxidation


The best choice for thermal oxidation when contaminants are high and there is constant demand for heat energy on site is normally recuperative oxidation. Waste gases are oxidised in a furnace and resulting heat is recovered with a boiler to steam, hot water or thermal fluid. The high temperatures and long residence times make this particularly suitable for treatment of odours as well as other pollutants.
The design is carefully tailored to the operating parameters which usually enables thermal efficiency gains to be made by pre-heating of the process air. Plants with air deliveries between 500 Nm3/h and 64,000 Nm3/h have been constructed.


Regenerative Oxidation


Regenerative Oxidation is generally the best choice when there is no additional demand for heat energy and VOC loadings are relatively low. Careful study of the process operating conditions, coupled with experience, careful design and the latest generation ceramic media can enable these units to achieve very high thermal efficiencies. With the appropriate design and relatively higher VOCs levels the need for a support fuel is reduced to the point that they can run auto-thermally. Air flows as low as 1,000 Nm3/h and as high as 330,000 Nm3/h have been constructed in our factories.


Regenerative Oxidation Combi

The Combi unit combines a recuperative thermal oxidiser and a thermal fluid recovery system in one compact neat unit.  These units are particularly suitable for the food or feed industries with air deliveries between 1000 and 5000 Nm3/h.


Odour Control Oxidation Concentration

With low concentrations of VOCs and very high air deliveries a process of roto-concentration is recommended.  Concentrations of 15:1 can be achieved relatively easily and 20:1 is now becoming possible. We have used roto-concentrators as a part of a larger regenerative oxidiser project. This reduces both the unit’s capital costs and the ongoing running costs.
Stationary Diesel Engine Exhaust Gas Treatment

Most waste to energy plants incorporate a stationary diesel engine driving an electrical generating set.  If the fuel used is bio derived then it needs treatment prior to release to atmosphere. We have considerable experience of the small thermal oxidisers necessary. This technology is also applicable to other applications in this area, such as sludge drying and thermal refuse treatment plants.

After Sales Service

Over 50% of the company personnel are dedicated to maintaining our plants. With strategically located qualified engineers located around the UK and globally and good availability of spare parts from our UK stores, means our equipment is easily serviced to give decades of trouble-free running.
