Nitrogen Pressure Swing Adsorption

Although oxygen and nitrogen gases are present in enormous quantities in our breathable air, a significant amount of money must be spent to access them separately in their gaseous or liquid form. In addition to the cost of the gas, further costs are incurred because of the special safety and logistic issues surrounding cylinder handling and storage. Still other costs to consider are tank or cylinder rental, potential liquid nitrogen evaporation, and the extra inventory sometimes held due to process variations.
