We offer dry and semi-dry desulfurization methods. Lime hydrate Ca(OH)2 or soda NaHCO3 can be used as a sorbent. For more demanding processes such as municipal waste or RDF (solid modified fuel) incinerator, desulphurization is supplemented by the dosing of additional sorbents, usually activated carbon, to ensure maximum effectiveness of flue gas cleaning. For the wet scrubber, we provide modifications such as refurbishment, addition of shower floors, droplets separators and even the installation of Tray technology, which significantly increases the efficiency of the entire absorber.
