Vapacid type activated carbon is manufactured from coconut shell and impregnated with metal oxides that give it a high capacity for the removal of gases and acid vapors present in air. These acids can be organic such as acetic acid or mercaptans or inorganic such as sulfur dioxide and sulfuric, nitric, hydrochloric and phosphoric acids.
In the case of hydrogen sulfide removal, Vapacid catalyzes the H2S – oxygen reaction:
2 H2S + O2 = S8 + 2 H2O
Unlike other impregnated carbons, Vapacid minimizes sulfuric acid formation by inhibiting sulfuric acid-producing side reactions.
VAPACID adsorbs more than twice as many mercaptans as unimpregnated carbon because it oxidizes them to disulfides.
(2 RSH R2S2), which on the one hand are less odorous, and on the other hand are more easily adsorbed.
Among the main applications of this product are: odor control in drainage vents (so-called
and in sewage treatment plants; corrosion control and component protection
in aggressive industrial environments; environmental control in museums or in manufacturing areas of
such as computer chips or pharmaceuticals; environmental control in processes
that use mineral acids.
– All types of vapors and acid gases.
– All types of organic vapors (although with lower capacity than non-impregnated carbon).
Compound with which organoleptic tests are suggested:
– Hydrogen sulfide (in gas phase it is called hydrogen sulfide:H2S: it is the typical rotten egg smell. It is produced by reacting ferrous sulfide with sulfuric acid).
Like all inorganic acids, it is a toxic compound, so it must be handled with care and in low concentrations.
Among acid vapors and gases, those mainly encountered in industry, commerce and society are:
Hydrobromic acid (HBr)
Carbolic acid (carbolic acid, phenol)
Hydrochloric acid (HCl) (also called muriatic acid)
Hydrofluoric acid (HF)
Phosphoric acid (H3PO4)
Nitric acid (HNO3)
Hydrogen sulfide (H2S) (typical rotten egg smell)
Sulfuric acid (H2SO4)
Hydroiodic acid (HI)
Hydrogen bromide (the correct name for hydrobromic acid in the gas phase)
Hydrogen chloride (the correct name for hydrochloric acid in the gas phase)
Sulfur dioxide (SO2)
Chlorine dioxide (ClO2)
Phenol (carbolic acid, carbolic acid, carbolic acid)
Hydrogen sulfide (the correct name for hydrogen sulfide in the gas phase)
Hydrogen iodide (the correct name for hydrogen iodide in the gas phase)
