Scientific and engineering principles of membrane gas separation systems development

Abstract

A key part in development of membrane gas separation is assigned to membrane materials, their properties, such as the separation selectivity and specific performance with respect to individual components of gas mixtures. At the same time, the role of a particular process and its features in the separation of gas mixtures are insufficiently accounted for and are often not considered at all. In this paper, the authors have tried to formulate the engineering principles of membrane systems development based on a specific task taking into consideration the dialectical relationship between the membrane properties and optimal process parameters, such as the mixture composition, pressure, hydrodynamic conditions, and the process organization.
