Steps of nitrogen removal to produce concentrated oxygen
Four steps are repeated in a cycle to remove nitrogen from the air. The blue and red arrows show the changes in the flow of pressurized air through the device in each step. This process is used in the device engineered by Professor Mahesh Bandi of the Nonlinear and Non-equilibrium Physics Unit to produce concentrated medical-grade oxygen.
