Traditionally, wet scrubbing and semi-wet desulfurization have dominated the market. However, that is expected to change in the coming years, as the advantages of Dry Injection Desulfurization (DID) become better known. Redecam considers DID to be the “state-of-the-art” technology and as its price tag has fallen, it is the only desulfurization system Redecam has chosen to offer. DID removes SO2 (sulphur dioxide), SO3 (sulphur trioxide), HCl (hydrochloric acid) and HF (hydrogen fluoride).
Regulations involving the emission of these gases are getting stricter, and this technology is increasingly on the radar at many Power, Metals & Mining, Biomass & Pulp and Paper facilities as well as at cement plants, among others.
