1.1 Purpose CHAPTER I INTRODUCTION The abundance of life on Earth depends on oxygen, which composes around 21% of our atmosphere. However, demand for high purity oxygen has risen tremendously to support new manufacturing processes and treat various medical conditions. Industrial uses for purified oxygen include steel production, chemicals, petrochemicals, glass, ceramics, and paper. The primary medical application is oxygen therapy for patients suffering from conditions such as asthma and COPD (Chronic Obstructive Pulmonary Disease). Generating nearly pure oxygen from air is possible through either cryogenic distillation or pressure swing adsorption (PSA). The high energy cost of cryogenic distillation limits its economic viability to large scale oxygen demand or when > 96% oxygen is required. PSA cannot separate oxygen and argon, which limits the maximum oxygen purity to 96%. Since purity above 90% is acceptable for most personal 1PDF Image | LIMITS OF SMALL SCALE PRESSURE SWING ADSORPTION
