Resource Utilization of Industrial Exhaust Gas
Ozone, as a highly oxidative gas,has strong disinfection and oxidation capabilities and is applied in municipal wastewater treatment, industrial wastewater treatment , flue gas denitrification, paper bleaching , and food processing. Due to its inherent instability, ozone must be generated on-site using dedicated ozone generators. In ozone generation processes, Vacuum Pressure Swing Adsorption (VPSA) oxygen generation technology is one of the important oxygen supply solutions:
· Lower capital investment: Compared with traditional cryogenic oxygen production, VPSA equipment investment costs are relatively lower.
· Stable oxygen purity: Produces oxygen with 90–93% purity, fully meeting the feed gas requirements of ozone generators.
· Operational flexibility: Capable of flexible load adjustment within a 30–110% operating range.
· Energy efficiency: Specific power consumption is controlled at 0.30 ± 0.02 kWh/Nm³.
With increasingly stringent environmental regulations and the ongoing implementation of China's “Dual Carbon” strategy, ozone technology is expected to see broader applications in advanced industrial wastewater treatment and multi-pollutant flue gas control. It is expected to drive greater market demand for VPSA oxygen generation equipment in the future.
