A mathematical investigation into nanoscale gas separation: Effects of pore size and temperature
Membrane-based gas separation is a process necessary for the realization of a clean energy world. Membranes comprise of nano-sized pores through which gas mixtures are separated due to the significantly different transport rates of each gas. For each application there is a desired flow rate (permeability) and purity of by-product (selectivity). By tuning pore size and operating temperature the desired outcome can be achieved. Here the mathematical equations that govern gas transport throughout the pores are combined and analysed to provide overall guidelines for tailoring pore size and operating temperature.
