SO₂ and Acid Gas Control Technologies
Our air pollution control systems have been effectively controlling emissions from coal-fired boilers and industrial process for decades. This vast experience enables our engineers to custom design a system that you can rely on to help meet your plant’s environmental requirements.

Wet FGD system
- Wet FGD Systems – we offer both open spray (single and double loop) tower and dual-flow tray designs.
- Spray Dryer Systems – our proprietary two-fluid nozzle design makes efficient use of reagents and energy while providing a highly reliable atomizing system.
- Dry Injection Systems – an economical, reliable solution when your plant requires lower levels of SO₂ and acid gas emission control.
- Activated Carbon Injection System for Mercury Control – proven, low capital cost systems.
- NOx (SNCR) Systems — High NOx removal rate, low ammonia slip, economical to operate.
- Wet Electrostatic Precipitators – designed to be a final polishing device to help collect the smallest and hardest to capture particles and mists, including SO₃ acid mist.
