ABSTRACT: The membranous biogas treating research allowed determine optimal parameters of the process, affecting the membrane separation efficiency, permeability and selectivity. The working pressure falls within the limits of 0.6 MPa. Themembranousgastreatingregularitiesinamembraneapparatusweredetermined. The concentration-permeability relation and pressure effect on the permeability were determined. A mass transport mechanism through the membrane pores was established. The membrane structure and material basic requirements and membranous process principle at the gas treating were established. Relation of the membrane mass-transfer coefficient to a permeate flow on the phase rate, the mass-transfer coefficient in the membrane pores on an inside diffusion coefficient showed that increase in the rate results in increase of the mass-transfer coefficient, and also that while the external mass-transfer resistance determines the overall process rate, the process can be intensified.
