Abstract
Procedure to energetically improve the manufacture of nitric acid and increase the concentration of the acid produced, through the catalytic oxidation of the ammonia that is sent, to a vaporized and reheated reactor, then passing the gases to an oxidation section in which they are put into contact with secondary air from a denitration section of the product nitric acid, whose gases pass, once oxidized, to an absorption section, from which the product nitric acid is extracted, the residual gases of said section being directed to a turbine for their expansion, characterized by the fact that the ammonia is reheated by the secondary air through one or more heat exchangers located between the air compressor and the denitration section, said reheating action of the ammonia being complemented by one or more heat exchangers of steam-ammonia equipped with the convenient means of reg ulation so that the steam consumption is minimal or nil.
