- Аннотация: According to the theoretical model, mass transfer of gases through membranes is determined by the diffusion and sorption stages; the coefficients of these stages are not constant characteristics for a given system and vary depending on pressure and temperature. A feature of the organization of flows in the process of membrane separation, for example, on roll and hollow fiber modules, is the change in the partial pressure of the components of the gas mixture as the permeate is extracted, and, therefore, permeability. The influence of the pressure and composition of the gas mixture on the permeability and selectivity of separation is analyzed with two systems as examples, namely the purification of natural and associated gases from carbon dioxide and the extraction of helium from natural gas.
