Calcium input for sulphur capture and emission compliance

In power generation and energy recovery, calcium-based sorbents neutralise sulphur dioxide and acidic combustion gases at source. Feed quality determines sorbent utilisation and scrubber reliability. Variability in chemical composition or particle size introduces inconsistency in capture rates. Controlled calcium inputs support stable, predictable desulphurisation across load conditions.

Current applications supported by our lime products

CFBC Boiler — In-Furnace Desulphurisation

Application context

Limestone injected directly into the circulating fluidised combustion bed for real-time, in-situ sulphur capture.

Process impact

Forms stable calcium sulphate within the combustion zone — reducing SO₂ at source before flue gas exits the system.

Common requirements

  • In-furnace SO₂ capture at source
  • Optimised Ca/S utilisation ratio
  • Stable bed temperature & combustion control
  • Reduced downstream FGD load
  • Handles variable fuel sulphur content

Applicable products

Flue Gas Desulfurisation (FGD) Sorbent

Application context

Precision-graded limestone is deployed in wet and dry scrubbing systems as the primary sorbent for SO₂ capture — where Particle Size Distribution is the defining variable in sorbent performance.

Process impact

Controlled PSD directly optimises the Ca/S ratio — reducing limestone consumption per unit of sulphur captured while improving overall absorption efficiency and scrubber stability.

Common requirements

  • Optimises Ca/S ratio for peak capture
  • Reduces sorbent consumption per cycle
  • Minimises internal scaling formation
  • Enhances reagent utilisation efficiency
  • Ensures continuous emission compliance

Applicable products

Boiler Injection & Furnace Emission Control

Application context

Fine limestone introduced into combustion zones and ducts for sulphur and acid gas interception.

Process impact

Reduces corrosion risk, stabilises ash behaviour, and lowers emission load before stack exit.

Common requirements

  • Source-level sulphur & acid gas control
  • Improved fly ash handling behaviour
  • Reduced fireside corrosion risk
  • Thermal efficiency across load cycles
  • Stable continuous emission outputs

What role does limestone quality play in emission control and scrubber reliability?

High CaCO3 purity with low impurity levels ensures stable scrubber chemistry, reduces scaling and fouling, and supports long-term operational reliability. This protects emission performance and plant uptime.

How does particle size influence sorbent performance and sulphur capture efficiency?

Controlled particle size optimises dissolution rate and reactive surface area. This maximises sorbent utilisation, reduces reagent consumption, and maintains consistent capture efficiency across varying load conditions.

Can limestone quality influence the commercial grade of FGD gypsum produced?

Consistent chemical purity and low contaminant levels in feed limestone directly affect the grade and marketability of FGD gypsum, enabling power plants to recover value from desulphurisation by-products.
