Abstract

1,139,285. Sulphuric acid. NAUCHNOISSLEDOVATELSKY INSTITUT PO UDOBRENIJAM I INSEKTOFUNGITSIDAM IMENI PROF. YA. V. SAMOILOVA. 9 Feb., 1967 [9 Feb., 1966], No. 6263/67. Heading C1A. The roaster gas containing not less than 1% by volume of water vapour and obtained by roasting sulphur-containing raw material having a fluorine content of more than 0À001% by weight is passed to a contactor for the oxidation of sulphur dioxide to sulphur trioxide, thus avoiding the poisoning of the catalyst. The roaster gas may have a dust content of not more than 50 mg. per cu. m. (S.T.P.) when it is passed into the contactor.
