Course content

The subject is offered every second year, next time spring 2012.
The goal for the course is to give a comprehensive understanding of membrane technology with reference to different membrane materials and the gas transport mechanisms through these, thus the difference in gas separation properties of the membrane materials will be explained , and give the basis for a good choice when membrane separation processes are considered.
The following topics are included: Transport of gases (ideal, non-ideal, polar and non-polar gases) through polymers, inorganic (carbon, glass, ceramics, metal) and hybrid (mixed matrix) membranes; and the influence of sorption, diffusion, adsorption, poresize, pore size distribution, in these materials. Separation of various gas mixtures at varying temperature and pressure. The importance of the material’s chemical structure, the physical properties of the gases, interaction between gases and membrane material, and possible degradation. Examples of environmental friendly membrane processes will be discussed (drying of natural gas, CO2-capture, recovery of VOC, upgrading of biogas, recovery of H2, among others).

Learning methods and activities

Colloquium. selfstudies. Individual report/article (will count for 25 % of the mark).

Recommended previous knowledge

Basic knowledge within membrane technology in an advantage. If possible, it is ecommended to follow the basic course in membrane technology offered 9th semester in the MSc-program at Department of Chemical Engineering. Alternatively a short introduction course will be offered.
