Title New method of decontaminating phenol-containing exhaust gases in shell moulding
Original title Eine neue Methode zur Entgiftung phenolhaltiger Abluft beim Giessen nach dem Maskenformverfahren [in German]
Bibliographic information June 1974, Vol.24, No.6, p.177-180. Illus. 6 ref.
Abstract Description of the method, based on wet oxidation by permanganate. Tests in a foundry in which shell moulding is carried out yielded a decontamination rate of 94%; the phenol concentration in the purified air was well below the threshold limit value. A curve illustrates the course of phenol build-up after pouring.
