| Summary: | <pre>High-purity hydrogen is required for clean energy and </pre><pre>a variety of chemical technology processes. A considerable part of hydrogen </pre><pre>is to be obtained by methane conversion and its separation from other hydrocarbon </pre><pre>gases not involved in energy production. Different alloys, which may be well-suited </pre><pre>for use in gas-separation plants, were investigated by measuring specific hydrogen </pre><pre>permeability. One had to estimate the parameters of diffusion and <span>sorption</span> to numerically </pre><pre>model the different scenarios and experimental conditions of the material usage </pre><pre>(including extreme ones), and identify the limiting factors. This paper presents </pre><pre>a <span>nonlinear</span> model of hydrogen permeability and its modifications in accordance with </pre><pre>the specifics of the experiment, the difference scheme for the solution of </pre><pre>the boundary-value problem, and the results of numerical modelling.</pre><pre> </pre><pre> </pre><pre> </pre> |
