Abstract
To describe gas transport through a bilayer membrane with a thin selective layer on the surface of a highly permeable gutter layer, it is for the first time proposed to take into account the interlayer resistance arising at the boundary of two membrane layers and a model of gas transport through a bilayer membrane is developed. Analytical expressions for the permeability and selectivity of such a membrane are obtained taking into account this resistance. It is shown that interlayer resistance can noticeably affect the transport characteristics of the membrane. It is found that, even in the case of a low diffusion resistance to gas transport of the gutter layer, its sorption and kinetic parameters affect the permeability and selectivity of the membrane as a whole.
期刊介绍:
The journal Membranes and Membrane Technologies publishes original research articles and reviews devoted to scientific research and technological advancements in the field of membranes and membrane technologies, including the following main topics:novel membrane materials and creation of highly efficient polymeric and inorganic membranes;hybrid membranes, nanocomposites, and nanostructured membranes;aqueous and nonaqueous filtration processes (micro-, ultra-, and nanofiltration; reverse osmosis);gas separation;electromembrane processes and fuel cells;membrane pervaporation and membrane distillation;membrane catalysis and membrane reactors;water desalination and wastewater treatment;hybrid membrane processes;membrane sensors;membrane extraction and membrane emulsification;mathematical simulation of porous structures and membrane separation processes;membrane characterization;membrane technologies in industry (energy, mineral extraction, pharmaceutics and medicine, chemistry and petroleum chemistry, food industry, and others);membranes and protection of environment (“green chemistry”).The journal has been published in Russian already for several years, English translations of the content used to be integrated in the journal Petroleum Chemistry. This journal is a split off with additional topics.
