Nitric acid production by the oxidation of ammonia on platinum gauzes constitutes one of the world's major chemical industries. In this article the author outlines some of the principal features of this process, and describes in some detail the chemical reaction taking place at the platinum surface. He also discusses the changes that occur in the gauze leading to metal loss during operation.
19-03-2008· The diagrams frequently focus on energy flow and its distribution to various sources or sinks, represented by arrows, the width of which indicates the amount of energy flow. Material flows are also frequently displayed with Sankey diagrams, and these are described, for example, as material flow charts (Koelbel and Schulze 1960).
