Dry sorbent systems that neutralise acid gases and capture particulates — with no scrubbing water and no effluent.
Flue gas is passed through a reactor where a dry alkaline sorbent — hydrated lime or sodium bicarbonate — is injected. Acid gases such as SO₂ and HCl react with the sorbent and neutralise.
The spent sorbent and dust are captured downstream in a bag filter. Because no water is used, there is no scrubbing effluent to treat — a key advantage where water is scarce.

Acid gases neutralised in the reactor.
Bag filter captures dust and spent sorbent.
Discharged via stack within norms.
No water is used — the residue is a dry, disposable powder.
Final specifications are engineered per site after requirement study.
