2020 REFINING PROCESSES HANDBOOK PROCESS CATEGORIES COMPANY INDEX OXYGEN ENRICHMENT Vacuum Swing Adsorption (VSA) On-Demand Oxygen Generation Application: Steel making, glass, pulp and paper, wastewater treatment, mining Feedstock-Air and energy (electrical) Air compression and vacuum generation Air filter Advantages: Main features: * Compact design layout * Fully packaged and pre-tested skids * Minimized schedule, erection and startup times * Automatic and unattended operation * Capitalization of more than 20 yr of operating and maintenance experience. Absorber Oxygen compression and backup Gas buffer Air blower Oxygen booster Absorber Description: VSA uses the process of air separation by adsorption. The basic principle of air separation by adsorption relies on the use of specific zeolite adsorbents for the selective adsorption of nitrogen over oxygen and argon. Products: Oxygen from 90%-93% purity Adsorption Exhaust Gaseous oxygen Liquid oxygen tank Vacuum pump Economics: CAPEX-$1 MM-$6 MM Utilities: Capacity, 40 tpd-130 tpd; specific energy, 265 kWh/t Installations: > 100 Licensor: Air Liquide Engineering & Construction Website: https://www.engineering-airliquide.com/vacuum-swing-adsorption Contact: airgases@airliquide.com Copyright © 2020 Gulf Energy Information.
