1 Introduction 10 However, any modifications of the PSA cycle organisation or slight alterations of process conditions influence the distribution of driving forces as a function of time within the production and regeneration steps. Those changes affect the local gas interstitial velocity, which again impacts, for instance, the local column pressure drop, the heat and mass transfer rate, and the axial dispersion of heat and mass [48,49]. Thus, the development of a predictive mathematical model becomes more challenging, especially in the case of kinetically-controlled nitrogen generation in the high-purity range. In addition, a critical discussion of the simulation accuracy as well as the explicit experimental and simulation data with exact values of approximation errors are given in this work. Finally, in light of the contemporary climate crisis, a particular focus on reduced energy consumption becomes a primary encouragement; since almost two-thirds of global electricity comes from the combustion of fossil fuels* [50], emitting large amounts of carbon dioxide to the atmosphere. * applies to data from 2019
