What it is
A limestone sorbent with engineered particle size distribution, formulated for controlled reactivity across wet scrubbing, dry injection, and in-furnace FGD systems.
What it does
- Delivers rapid, consistent SO₂ neutralisation
- Optimises Ca/S ratio for peak sorbent utilisation
- Controls absorption kinetics and scrubber chemistry
- Minimises scaling, fouling, and impurity carryover
- Maintains stable slurry rheology under continuous operation
- Supports reliable emission compliance across process cycles
Where it’s typically used
Wet and dry FGD systems, CFB boilers, and industrial scrubbing units where consistent sulfur capture and scrubber stability are operationally non-negotiable.

FAQs
If you have questions about limestone products, specifications, or typical applications, the answers below address some of the most common topics. For anything more specific, our technical team is happy to help.
Why does particle size matter more than purity in FGD performance?
Purity sets the chemistry. Particle size governs the reaction. Sulfa Fix's engineered PSD controls how fast and how completely SO₂ is neutralised — optimising the Ca/S ratio, reducing reagent consumption, and preventing the scaling and slurry instability that degrade scrubber performance over time. Purity without PSD control is specification without process control.
How does Sulfa Fix perform across both wet scrubbing and dry injection systems?
Each grade is matched to its system. Granules for CFB in-furnace capture. Powder for wet scrubbers. Sub-0.5 mm fines for dry injection. Same specification discipline — different particle architecture. No reformulation. No performance compromise across applications.
What does Sulfa Fix deliver beyond SO₂ removal?
Compliance is the floor, not the ceiling. Sulfa Fix stabilises scrubber chemistry, protects refractory and equipment integrity, controls gypsum byproduct quality, and reduces unplanned downtime — across power generation and industrial environmental treatment operations alike. Consistent emission performance. Lower total operating cost. One product qualified across both industries.
