Gas purification and separation are important in a variety of industrial applications and plants. The rising energy demand of the world’s population necessitates a rapid shift to alternative renewable energy sources, such as hydrogen. Membrane technology has a lot of potential in the gas separation sector because of its simplicity, cost-effectiveness, and low energy requirements, in comparison to the conventional methods. Our group deals with engineering strategies such as functionalization, and creating polymer nanocomposites to achieve unprecedented Physico-chemical properties and gas separation performance. We primarily work with our own developed gas permeability setup along with PMI Diffusion Permeater.
