Products Description

VPSA (Vacuum Pressure Swing Adsorption) oxygen production equipment utilizes an advanced adsorptive gas separation technology. It separates nitrogen and moisture from the air, efficiently producing oxygen with a purity of 80% to 95%. VPSA oxygen production equipment plays a significant role in traditional industries such as steel, glass fiber and special materials, papermaking,wastewater treatment, cement, ceramics, and glass furnaces, as well as in non-ferrous smelting, solid waste recycling, and other fields.
GNEE has developed a VPSA process flow suitable for high-speed centrifugal blowers, applying the technology of high-speed direct-connected centrifugal blowers to VPSA oxygen production equipment, reducing equipment wear and effectively extending equipment life.
GNEE's VPSA oxygen production equipment is an energy-saving and environmentally friendly product. Compared to traditional technologies, the blower and vacuum pump can save energy by 8-12%, with low noise and intelligent control, reducing the overall cost of equipment oxygen production.
Principle of VPSA Oxygen Generation
VPSA (vacuum pressure swing adsorption) is separating oxygen from air by vacuum decompression for desorption.
The pressure swing adsorption oxygen generation uses air as the feed gas which is forced by a blower to pass under pressure through the adsorbent bed. The nitrogen, carbon dioxide and water in the air are adsorbed by the adsorbent, and the remaining components pass through the absorbent for richer oxygen. And then as the pressure is being lowered, the nitrogen, carbon dioxide and water adsorbed on the adsorbent are released and the adsorbent can be regenerated in this way. The reciprocating process makes up the basic principle of vacuum pressure swing adsorption oxygen generation.
Products Applications
Chemical Industry Applications
In the chemical industry, VPSA oxygen generators play a crucial role. During chemical production processes, many chemical reactions require the participation of oxygen, such as oxidation reactions and combustion reactions. VPSA oxygen generators can provide oxygen with adjustable purity for chemical plants, meeting the specific oxygen requirements of different processes. In the raw gas preparation stage, the oxygen produced by VPSA oxygen generators can be used for oxy-fuel combustion, improving combustion efficiency and reducing energy consumption. Relevant data shows that after adopting VPSA oxygen generators for oxy-fuel combustion, the energy consumption of ammonia synthesis plants can be reduced by 10% - 15%, significantly enhancing the production efficiency and competitiveness of chemical enterprises.
Metallurgy Industry
The metallurgy industry is also an important application scenario for VPSA oxygen generators. In the smelting process of iron, steel, and non-ferrous metals, oxygen, as a combustion-supporting agent and oxidizing agent, can accelerate the smelting process and improve metal output and quality. Taking iron and steel smelting as an example, in the converter steelmaking process, blowing high-purity oxygen into the furnace can rapidly oxidize impurities such as carbon, silicon, and phosphorus in the molten iron, thereby shortening the smelting time and improving the quality of molten steel. VPSA oxygen generators can flexibly adjust oxygen output and purity according to the needs of smelting processes, providing stable and reliable oxygen supply for metallurgical enterprises. After a large iron and steel enterprise adopted VPSA oxygen generators, the smelting cycle of converter steelmaking was shortened by approximately 10 minutes, steel output increased by 8% - 10%, and production costs were reduced, enhancing the enterprise's advantages in the market.
Composite Material Production
In the glass manufacturing industry, VPSA oxygen generators have also brought significant improvements to the production process. During glass production, the high-temperature melting stage requires a large amount of heat, and the traditional air combustion method is relatively inefficient. Using oxygen-enriched air provided by VPSA oxygen generators for combustion can increase the flame temperature, accelerate the melting speed of glass raw materials, reduce fuel consumption, and at the same time reduce the emission of nitrogen oxides in exhaust gas. Studies have shown that after using oxy-fuel combustion technology, the fuel consumption of glass furnaces can be reduced by 15% - 20%, and nitrogen oxide emissions can be reduced by about 30%, achieving energy conservation and emission reduction while improving the production quality and efficiency of glass.
