Description
The FRP Desulfurization Tower is an industrial exhaust gas treatment system designed to remove sulfur dioxide and other acidic pollutants from flue gases. Constructed from corrosion-resistant glass fiber reinforced plastic, the tower utilizes a wet scrubbing process in which alkaline absorbent liquid is sprayed counter-currently to the incoming gas stream.

Features
▲ Superior Corrosion Resistance: FRP construction ensures long-term reliability in acidic/alkaline and high-humidity environments, with a service life of 15–20 years.
▲ High Removal Efficiency: Multi-stage spray and optional packing layers maximize gas-liquid contact, enabling >95% SO₂ removal even under variable load conditions.
▲ Lightweight & Easy Installation: Compared to steel or concrete towers, FRP towers are significantly lighter, reducing foundation requirements and installation time.
