Limestone slurry preparation, absorber mixing and gypsum crystallization systems for flue gas desulfurization. Combined abrasion and corrosion resistance with 24/7 continuous operation.
Flue Gas Desulfurization (FGD) is a wet scrubbing process used to capture SO₂ from the flue gas of coal-fired thermal power plants, cement plants and smelters. Limestone slurry contacts the flue gas in the absorber tower to form CaSO₃/CaSO₄, which is then crystallized as gypsum. Mechanimix designs the mixing systems needed in all three key tanks — slurry preparation, absorber and gypsum — end to end.
Super Duplex or Cr₂₇ impellers with rubber-lined tanks to withstand the combination of low pH, high solids content and chloride ions.
Guarantees solids suspension with low power consumption in high-viscosity, dense-slurry environments.
Bearings, seals and gearboxes specified for MTBF > 40,000 hours to support 24/7 operation without redundancy.
pH feedback closed-loop dosing stabilizes SO₂ capture efficiency at 95%+.
Controlled supersaturation and residence time produce marketable-grade gypsum (CaSO₄·2H₂O > 95%).
Tank geometry and baffle configuration optimized with CFD; kW/m³ below industry average.
This system consists of integrated components selected from MechaniMix's product portfolio.
Primary mixing unit for absorber, slurry and gypsum tanks; long-shaft, multi-impeller configurations.

Slurry mixing experience in thermal power plants and cement works; uninterrupted availability of critical equipment.
FGD service is both abrasive and corrosive; Mechanimix provides a material recipe that addresses both mechanisms together.
Optimized impeller design reduces energy consumption; committed spare-parts stock makes planned maintenance predictable.
Fast on-site response and in-stock seals and impellers keep annual downtime below 8 hours.
