Resource Utilization of Industrial Exhaust Gas
Lirun Technology’s VPSA-O₂ technology provides an economical and efficient oxygen enrichment solution that has been widely applied across multiple industries. The system is based on the principle of selective adsorption: feed air (0.03–0.05 MPa) is delivered by a blower into the adsorption tower, where specialized adsorbents preferentially adsorb nitrogen and other impurities, while high-purity oxygen (90–93%) is continuously produced at the top. A PLC-based intelligent control system enables dual-tower alternating operation. Once saturated, the system automatically switches to vacuum desorption (-0.08 to -0.092 MPa), ensuring stable oxygen supply.
Lirun Technology integrates advanced radial-bed design, stable high-efficiency adsorbents, reliable high-frequency large-diameter butterfly valves, optimized power equipment, and a comprehensive engineering management system. This ensures low energy consumption, large-scale production, and safe, user-friendly operation for oxygen plants.
