Abstract

19,792. Norsk Hydro-Elektrisk Kvaelstofaktieselskab. Sept. 20, 1913, [Convention date]. Drawings to Specification. Acids, concentrating.-In concentrating nitric acid in counter-current with sulphuric acid, the requisite temperature is maintained in the concentrating-tower by introducing the nitric acid as a mixture of liquid and vapour, preferably produced by boiling the nitric acid outside the concentrating-tower.
