Design of Novel Polymeric Membranes Using Molecular Simulation Techniques

Polymeric membranes are used widely in separation devices for various industrial processes. In this project, the aim is to develop stable membranes for the separation of light and heavy hydrocarbons in natural and petroleum gas. Existing polysiloxanes are inadequate for such separations due to stability problems. Molecular dynamics is used to study the structure, thermodynamic and transport properties of novel silicon-based polymers. Furthermore, diffusion coefficients and solubilities of light hydrocarbons are calculated. Simulation work is supported by experimental measurements performed at the Russian Academy of Sciences.
