Oxygen generation by vacuum pressure swing adsorption

Fast, cost-effective oxygen on demand. Demand for on-site oxygen generation solutions continues to rise across a number of industries. Vacuum Pressure Swing Adsorption (VPSA) technology is an increasingly popular way of meeting this demand. VPSA involves separating air into its constituent components by means of adsorption. In other words, the gas molecules bind with adsorbent material at different rates depending on the pressure. This allows operators to single out one particular gas from air. The growth in demand for VPSA technology is largely attributable to its simplicity, reliability and low operating costs.

Experience counts
World leader in adsorption technology, Linde has designed and supplied more than 600 adsorption plants worldwide – including the world‘s largest units. We also offer the highest availability levels in the industry. Our adsorption systems are therefore the solution of choice where performance, flexibility, availability and reliability are key success factors. High quality and easy accessibility to all components also ensure ease of maintenance.

Adsorption applications
Major applications include the recovery of high purity hydrogen, methane and carbon dioxide as well as the generation of oxygen and nitrogen. Linde oxygen VPSA systems are successfully deployed in industries as diverse as iron and steel, metals, mining, chemicals, pulp and paper, water treatment, glass, food and fish farming.

Large portfolio for all capacity needs
Our VPSA units for oxygen generation come in multiple sizes and shapes to suit individual needs. All systems support on-stream applications requiring gaseous oxygen with purity levels of up to 95%. Capacities scale up to 10,000 Nm³/h (342 tpd) – with one single train.

In addition, we have developed a fully containerised C-series supporting oxygen streams of up to 2,000 Nm³/h (68 tpd). This C-series is ideal for customers looking to combine the benefits of rapid deployment with maximum cost efficiencies.
