Abstract
270,989. Petersen, H. Dec. 16, 1926. Sulphuric acid. - In order to avoid a preliminary drying treatment in working up sulphur dioxide gases containing moisture into sulphuric acid, the gas stream is divided, a portion only being passed into the denitrating enclosure, the remainder being introduced into those parts of the plant requiring moisture for the acid-forming reaction. The denitrating enclosure may take anv form which will effect intimate contact between the acid and the gases; a tower packed with filling having an average diameter of only 40 mms. or less may be used.
