Performance Optimization of the Low-Capacity Adsorption Oxygen Generator

Abstract

This paper presents an innovative method of optimizing energy consumption by a low-capacity adsorption oxygen generator. As a result of the applied optimization, reduction in the energy consumption of oxygen separation by about 40% with a possible increase in the maximum efficiency by about 80% was achieved. The experiments were carried out on a test stand with the use of a commercially available adsorption oxygen generator using the PSA technology. The experimental analysis clearly shows that the adsorption oxygen generators offered for sale are not optimized in terms of energy consumption or capacity. The reduction of the oxygen separation energy consumption was achieved by appropriate adjustment of the device operating parameters for the given adsorption pressure and maintaining an appropriate pressure difference between the adsorption bed and the product tank.
