Determination of Gas Transport Parameters of a Bilayer Membrane Using the Method of Statistical Moments of the Sorption Kinetic Curve
A model of gas sorption kinetics for a bilayer membrane consisting of a selective polymer layer applied to a highly permeable substrate has been developed. For the first time, analytical expressions for the first and second-order moments of the kinetic sorption curve of the bilayer membrane have been derived. These expressions have been used to propose a method for determining the permeability coefficients of the gas transport through the membrane layers of the bilayer membrane. The results of this work can be applied to evaluate the gas permeability coefficients of composite membranes.
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.
