    摘要: A process for making fuming nitric acid involving the reacting of nitrogen dioxide gas with dry hydrogen chloride gas to produce the fuming nitric acid directly, and to produce as a co-product nitrosyl chloride gas; separating the formed liquid fuming nitric acid from the reaction gases and co-product gas; and stripping the liquid product and demisting the gaseous product to complete their separation.
