Wet FGD
Mature limestone/gypsum wet scrubber technology with high reliability and strong tolerance to flue-gas variations. Suited to coal and heavy-oil fired units with stringent emission requirements.
Flue gas desulfurization (FGD)
Flue gas desulfurization systems, designed around your process.
From wet and semi-dry FGD to integrated downstream equipment, Chengshuo delivers complete systems for new installations and retrofit projects.

Choose the right FGD process for your plant.
Engineering begins with the fuel, process conditions, emission requirements and site constraints.
Semi-dry FGD
Spray dryer absorber or circulating semi-dry solutions with simpler water balance and lower wastewater generation. Well suited to medium sulfur fuels and space-constrained sites.
Integrated FGD systems
FGD combined with upstream dust removal and downstream equipment such as mist eliminators, heat recovery and reheaters for optimized performance and footprint.
Designed around the full gas path
Flue-gas conditions
Evaluate SO2 load, particulate, temperature, moisture and flow variations to define robust process margins.
Absorbent & reagent handling
Limestone, lime or other reagents with proper storage, preparation, slurry management and dosing control.
By-product management
Gypsum dewatering, storage and handling or alternative by-product treatment and utilization.
Water & utilities
Process water balance, closed-loop design where appropriate, and integration with plant utilities.
Emission targets
Design to meet applicable SO2 limits and future requirements with stable long-term operation.
From process design to commissioning - one accountable team.
Process design
Fuel and flue-gas analysis, process simulation, equipment sizing, P&IDs and control philosophy.
Equipment manufacturing
