600MW FGD Absorber
Southeast Asia
The client required a dual-tower FGD absorber system capable of handling 600MW of flue gas from a coal-fired plant. The operating environment involved continuous exposure to wet SO₂ at 50–80°C, pH 1–3 slurry, and high chloride concentrations — conditions that rapidly degrade unprotected carbon steel.
Jasmino delivered the project as a single-source solution — engineering design, equipment manufacturing, and corrosion protection were executed in-house. Two 16m-diameter absorber towers were fabricated from carbon steel with full internal rubber lining using our proprietary chlorobutyl compound, selected for its resistance to dilute sulphuric acid and chloride-bearing slurry.
Our approach
Process Engineering
Full thermodynamic modelling and CFD analysis of gas flow distribution. Designed spray headers, mist eliminators, and sump geometry to maximise SO₂ removal efficiency above 96%.
Structural Design
ASME VIII Div 2 design for both towers, with finite element analysis for wind and seismic loading. Total steel weight: 340 tonnes per tower.
Rubber Lining
2,400 m² of CSM-backed chlorobutyl rubber applied at our India facility. Spark-tested at 20kV per layer with zero defects recorded across all panels.
Site Erection
Modular delivery in 16 sections per tower. Our field technicians supervised erection, welding, and final lining repairs on-site over a 6-week installation window.
