denitrificator (den it rif ikat or)

[As deni trify + -at or. See denitrification.] An apparatus used in sulphuric-acid factories to impregnate the sulphurous acid obtained from burning sulphur or pyrites with nitrous fumes. It consists of a tower in which strong oil of vitriol charged with nitrous fumes from the Gay-Lu ac tower and weak chamber-acid (sulphuric acid as drawn from the leaden chambers of the factory) are allowed to flow down over pieces of flint or coke against the current of hot sulphurous gases. The strong acid on dilution gives up its nitrous fumes, which are swept on with the other gases into the acid chambers. Also called Glover's tower or denitrating tower. denitrify (de-ni'tri-fi), v. i.; pret. and pp. de nitrified, ppr. denitrifying.
