In an ammonia oxidation plant for the manufacture of nitric acid the rhodium-platinum alloy catalyst gauzes must be pickled at intervals to remove accumulated impurities such as iron oxide and so to avoid a reduction in catalytic efficiency. This article outlines a method recently devised to determine the optimum frequency of pickling required to ensure consistent operation at high efficiency.
