Unformatted text preview: hronic obstructive pulmonary disease (COPD) is increasing COPD is 4th leading cause of death worldwide Hospital Unit Large hospitals spend an estimated $170,000 per a year on oxygen Approximately 350 large hospitals in United States On-site unit allows for: – unlimited supply of Oxygen – Annual savings Air Separation Air is used as feed stock Oxygen is separated based on physical characteristics Must remove Nitrogen and Argon for 99% Oxygen purity Air Separation Methods Cryogenic Distillation Membrane Separation Pressure Swing Adsorption (PSA) Cryogenic Separation Cryogenic Separation Leading process for producing 99% oxygen in bulk. Involves liquidifying air and distilling the liquid air to separate the Oxygen, Nitrogen, and Argon. Can be sold in a liquid form. 1 L of liquid Oxygen = 860 L of gaseous Oxygen Cryogenic Separation Drawbacks – Process uses large bulky equipment – Energy requirements are substantial unless demand is more than 60 tons of oxygen per a day – Liquid oxygen evaporates back into the atmosphere over time Membranes Membranes Permeable materials used to selectively separate Oxygen, Nitrogen, and Argon Large and medium scale production. Pressurized air is passed through the membrane and is separated by permeability ch...
