Pollution control

Environmental and energy policies worldwide have taken a new direction to reduce pollutant emissions and protect the environment.

We offer a full technical, commercial, and environmental advisory capability in pollution control technologies for both retrofit and new build, biofuels, biogas, biomass, coal, diesel, gas, oil, and waste plant.

In response to a clear need to support climate change and pollutant emissions reduction strategies for both the power industry and other energy-intensive processes worldwide, we offer a full technical, commercial, and environmental advisory capability in pollution control technologies for both retrofit and new build, biofuels, biogas, biomass, coal, diesel, gas, oil, and waste plant.


Our expertise in particulate abatement systems includes wet or dry electrostatic precipitators, fabric filters, wet scrubbers and inertial separators.

Ash utilization

Our expertise in ash processing techniques means we are well placed to provide the full spectrum of advisory services to our clients. Sustainable solutions for the ash produced from thermal generation processes need to be considered, especially where facilities for long-term storage are limited. Ash products can be valorized and sold to third parties, minimizing the environmental impacts of the plant, reducing the quantities stored at site, and generating an additional revenue stream.

Flue gas desulfurization (FGD)

Post-combustion FGD technologies produce cleaner flue gas with reduced emissions having converted sulfur oxides (SOx) back to elemental sulfur. Our expertise in this area covers wet FGD, seawater FGD, semi-dry FGD, dry FGD, and in-furnace injection.

Nitrogen oxides (NOx) emission reduction

Our capability in NOx emission reduction technologies covers both primary methods (those related to the combustion process designed to reduce the production of NOx) and secondary methods (post-combustion processes that convert NOx back to elemental nitrogen), resulting in cleaner flue gas with lower emissions.

Our expertise in the primary methods covers low NOx burners, gas reburn, over fire air (OFA) and flue gas recirculation (FGR). Our expertise in secondary methods includes selective noncatalytic reduction (SNCR) and selective catalytic reduction (SCR).

Particulate abatement

Fuel combustion results in the formation of particulate matter, which can be carried with the flue gas stream into our atmosphere. The control of particulate emissions lies at the forefront of emission controls. Along with their environmental impact, these particulates have been linked to heart disease and lung cancer.
