Air separation can produce a series of high purity gaseous or liquid products, including oxygen, nitrogen, and other rare gases. Common separation methods include cryogenic distillation, Pressure Swing Adsorption (PSA), and Vacuum Pressure Swing Adsorption (VPSA).

Pressure Swing Adsorption Separation

Pressure Swing Adsorption (PSA), for separating oxygen/nitrogen, is widely used in medium and small-scale air separation plants. With low investment costs, low energy consumption, and ease of operation, PSA separation techniques are quite common aside from traditional cryogenic air separation. Oxygen or nitrogen is separated, which allows oxygen or oxygen-enriched air to be captured.
