Abstract
Using a computational experiment, the existence of the abnormal regimes of nonequimolar diffusion in three-component gas-vapor mixtures such as acetone-methanol-air, hydrogen-water-carbon dioxide, and hydrogen-ammonia-nitrogen is shown. Due to osmotic and reverse diffusion, the molar fraction of water vapors and ammonia can be increased by more than a factor of two in the individual segments of a Stefan tube in comparison with their concentration at the inlet.
