METHOD OF PRODUCING NITRIC ACID
Abstract
The object of the invention is a method of obtaining nitric acid from a gaseous mixture, which contains nitrogen oxide, oxygen and other gases by the method of cooling the mixture and passing it through an adsorber with fluidized layers of absorbent, for example, silica gel, which is distinguished by the fact that, for the purpose of lowering the cost and simplifying the technological process, steam is passed into the absorbent and separated out by desorption under a vacuum at a temperature of 80 to 120C with the blowing through by air nitric acid in the vapor phase. For the purpose of intensifying the process, the adsorption and synthesis are accomplished under pressure up to 10 kg/sq. cm.
