HySORB™ – The Integrated CO2 and SO2 Capture Solution Solution for Coal Based Power Industry
No Compression. No Transportation. No Storage.
Just one system that captures COâ‚‚ + SOâ‚‚ and turns them into value.
One System. Two Pollutants. Zero Compromise.
HySORB™ is a breakthrough emissions control technology that eliminates the need for both Flue Gas Desulfurization (FGD) and standalone Carbon Capture units. Instead, it delivers a single, integrated solution that simultaneously captures sulfur dioxide (SOâ‚‚) and carbon dioxide (COâ‚‚) in one compact process — at lower cost, with higher efficiency, and with commercially valuable byproducts.
Why SOâ‚‚ is the Hidden Barrier to Carbon Capture
One of the biggest hurdles in post-combustion carbon capture is sulfur dioxide (SOâ‚‚) in flue gas. Conventional amine-based COâ‚‚ capture systems are extremely sensitive to SOâ‚‚ — even small amounts lead to the formation of heat-stable salts, which degrade the solvent, increase energy demand, and drive up maintenance costs. To prevent this, global carbon capture plants first rely on wet flue gas desulfurization (FGD), followed by a costly deep FGD stage to bring SOâ‚‚ levels down to as little as 1–2 ppm before COâ‚‚ capture can even begin. This is where Indian power plants face a unique challenge. Typical coal-based flue gas in India contains 200–500 ppm SOâ‚‚, often averaging ~250 ppm, which is far higher than the tolerance limits of conventional capture systems. Without installing both FGD and deep FGD — a multi-stage setup that demands massive space and capital — COâ‚‚ capture becomes practically impossible. HySORB™ eliminates this barrier by directly handling raw flue gas with high SOâ‚‚ levels, making simultaneous SOâ‚‚ and COâ‚‚ capture possible in a single step — no deep FGD required.
A Third Way: The HySORB™ Integrated Solution
HySORB™ eliminates the need for both FGD and separate carbon capture units. Instead, it uses a dual-alkali slurry (sodium hydroxide + calcium oxide/hydroxide) in a single absorber vessel to directly handle raw flue gas.
Here’s how it works:
-
SOâ‚‚ Capture → Neutralized into calcium sulfite (CaSO₃) or sulfate (CaSOâ‚„).
-
COâ‚‚ Capture → Absorbed by NaOH, mineralized into calcium carbonate (CaCO₃). Self-Regenerating Cycle → NaOH regenerates in situ, avoiding costly solvent replacement or thermal regeneration.
-
Valuable Byproducts → High-purity precipitated calcium carbonate (PCC) is recovered, opening new revenue streams.
