equipment for producing nitric acid by Ostwald's process. Selection of reactor mainly depends on three parameters; type of reaction, process condition and mode of catalyst exposure. Fixed bed reactor is best suited for the reaction taking place in the process, also, the selection of 90% Pt with 10% Rh as catalyst is best suited.
