The paper is devoted to studies of gas flows and mass transfer in a two-stage catalytic system recently applied in ammonia oxidation at nitric acid plants. Numerical studies are performed by reducing a system to a flat-periodical set of slit channels. Mathematical model based on two-dimensional Navier–Stokes equations with periodicity boundary conditions is used. Dependence of a system performance on a distance between stages is investigated and found to have a non-monotonous character.
