Ultra-reliable sulphur and dioxin removal

Gas Suspension Absorber (desulphurisation)

Recognised as the most reliable and flexible option for removing sulphur dioxide (SO₂), Gas Suspension Absorbers (GSAs) can be added to existing cement, petcoke, carbon black and metallurgical plants.

Characterised by low sorbent consumption, our GSA desulphurisation solution achieves an SO₂  removal rate of 98%, with equally impressive rates for HCI, Hg, HF and dioxins.

Ensures compliance with multiple emission limits

GSAs (desulphurisation) are a smart add-on for plants seeking to comply with stringent sulphur removal limits.

Their small footprint and modular design makes them relatively flexible to install in confined plant spaces compared to traditional flue gas desulphurisation (FGD) solutions.

And once in operation, they offer low maintenance costs while maintaining consistently high desulphurisation rates.

Case story

Reducing SO2 by more than 97%

It seemed like missions impossible: install a high-performance GSA desulphurisation solution at a cement plant in a tight installation window – and achieve results similar to those of more expensive wet scrubbers. Read how the project for Norcem in Norway reduced SO2 by 97.3%.

Case story

Dioxin removal of >99.9 %

China’s special economic area of Shenzhen produces a lot of waste. And we were selected to help turn it safely into energy for the region’s burgeoning population. Following installation of GSA desulphurisation solutions and other APC equipment, we lowered dioxin emissions to 0.1 mg/Nm³ – a removal efficiency of >99.9 %.
