Different systems of gas treatment which increase the uptake effectiveness of acidic contaminants in industrial fumes, from calcium carbonate to quicklime salked lime.

Calcinor produces a range of products specific for this application called NATURDEP®. These contain high surface area calcium hydroxides, which increase the effectiveness or uptake of acidic contaminants, generating fewer residues.

All industrial thermal processes, (cooking, combustion, curing…) generate naturally acidic contaminated gases (fluorine, chlorine, sulphur…). These gases cannot be directly emitted into the atmosphere until they comply with a series of requirements and emission limits. The various gas treatment systems can be divided as: wet, semi-wet, semi-dry and dry. Within these systems, different products can be used from calcium carbonates to quick and hydrated lime, both injected in whitewash form.
