Cost efficient oxygen concentrator with PSA technology

Abstract

Normally atmospheric air contains mixture of gases like nitrogen (78%), oxygen (21%), and small amount of lot of other gases like carbon-di-oxide (0.03%), hydrogen. Oxygen concentrator is a device that concentrate (or) separate oxygen from ambient air by specifically removing nitrogen by process of Pressure Swing Adsorption (PSA). Pressure Swing Adsorption is a technique that separate oxygen from a mixture of gases depending on pressure to which molecular characteristics and affinity for a zeolite (Natrolite). The proposed output of Oxygen concentrator with Pressure Swing Adsorption technology is economical and high-efficient. The experimental results of the proposed system supplied the oxygen at the purity of about 94.7% for the low velocities of 0.5-3 L/min. It is concluded that the system provides a good performance when considered that a patient with the COPD should take the oxygen at the purity of 90% or more for the low velocities of 0.5-3 L/min. On comparing with other oxygen concentrator available in the market, this proposed system is highly cost effective and comparatively lesser in weight. As per the experiments conducted using the proposed system provides comparatively less noise and works efficiently for long time and oxygen purity is also high. Since, this proposed system has these many features. This is so much helpful for peoples who can’t able to afford market available oxygen concentrator.
