Flue gas treatment plants are offered in combination with drying and/or combustion technologies. Comprehensive process knowhow combined with selected flue gas cleaning technologies enable compliance with stringent emission limits. Gaseous treatment using advanced thermal and catalytic oxidation processes enables control of odour from municipal/effluent treatment plants, NOx and dioxin abatement, and removal of VOCs generated by solvent using/producing processes.

Gas Cleaning
CALVERT® Collision Scrubber

Utilises a special collision process for maximizing the action of venturi throats. Ideally suited for all types of incinerator off-gas cleaning applications as well as for any other applications requiring high particulate matter collection efficiencies.
