Desulfurization (DeSOx) – Redecam Group
Advantages of our Dry Injection Desulfurization (DID) compared to wet flue gas desulfurization (Wet FGD): CAPEX is usually 4 times less, but in some cases can be 1/10 the price. Significantly more compact: requires a dosing silo and at times a reactor vs. a footprint of up to 5,000 m 2 (54,000 ft 2) OPEX for water and electricity is much lower.
