OxiPlant works on the principle of Pressure Swing Adsorption (PSA). The device consists of two specially fabricated stainless cylinders, each filled with a measured quantity of a specially made material called Zeolite. Dry, cooled and Pressurized air is alternatively passed through these cylinders. Nitrogen molecules get thermodynamically adsorbed by the zeolite crystals, allowing oxygen to flow out as a desired product. While this principle has been well known for over a century, the challenge lies in engineering a solution around the principle. Building OxiPlant involved mechanical design and fabrication, pneumatics circuits with proper understanding of pressure, temperature and flow controls, and more critically electronics which control, monitor, and automatically operate the entire oxygen production cycle.
Uniqueness of OxiPlant and its differentiation from commonly available concentrators lies in its Configurability, Flexibility, Scalability, and Monitorability. It is configurable to support many alternate processes such as PSA, VSA, VPSA etc. It is flexible to support production of Oxygen or Nitrogen or other gases. It is scalable to higher throughput up to about 20 lpm. It is monitorable as many temperatures, pressure and flow probes can be hooked up to provide valuable performance data that would form basis of plant tuning.
Prof. M R Doreswamy, Hon'ble Chancellor, has congratulated Tejas P Karanji on his achievement and encouraged him for more inventors.
