Introduction: Behind the Rigid Demand for Oxygen, a Revolution in Oxygen Generation Technology
Oxygen, known as the “industrial blood” in fields such as industrial production, medical and health care, energy conservation and environmental protection, its stable supply and cost control are directly related to enterprises’ production capacity, operational efficiency and core competitiveness. Traditional oxygen generation methods such as cryogenic air separation and liquid oxygen storage have long faced pain points such as large investment scale, high energy consumption, large floor space and inconvenient start-up and shutdown, making it difficult to meet the urgent demand for flexible, efficient and energy-saving oxygen supply in modern industries.
Against this background, Vacuum Pressure Swing Adsorption (VPSA) oxygen generation technology has emerged as the mainstream choice in the oxygen generation field with its disruptive advantages. As a high-tech enterprise specializing in the R&D, production, sales and service of VPSA oxygen generation equipment, Jiangsu Minnuo Group has created high-performance VPSA oxygen generation equipment suitable for multiple scenarios based on more than 20 years of industry accumulation and core technological breakthroughs. It injects green and efficient oxygen supply power into thousands of industries and redefines the value standards of the oxygen generation industry.
I. VPSA Oxygen Generation Technology: Decoding the Core Logic of Efficient Oxygen Supply
VPSA (Vacuum Pressure Swing Adsorption) oxygen generation technology, its core principle is to use the selective adsorption characteristics of molecular sieves for nitrogen and oxygen in the air to achieve the separation and purification of oxygen through pressure changes. Compared with traditional oxygen generation technologies, the advantages of VPSA oxygen generation equipment can be called “all-round crushing”:
1. Energy Conservation and Consumption Reduction, Operational Costs Reduced by 30%+
Traditional cryogenic air separation equipment needs to cool air to -196℃ to achieve gas-liquid separation, which consumes a lot of energy; while VPSA oxygen generation equipment operates at normal temperature and pressure, completing the adsorption and desorption cycle only through the coordination of vacuum pumps and compressors. The energy consumption per unit of oxygen is as low as 0.35-0.5kWh/Nm³, which is more than 40% energy-saving compared with cryogenic air separation and saves 30%-50% of operational costs compared with liquid oxygen supply. Long-term use can accumulate huge energy-saving benefits for enterprises.
2. Ready to Use, Flexibly Adapting to Multiple Working Condition Requirements
VPSA oxygen generation equipment has a short start-up time, which can produce qualified oxygen in only 15-30 minutes. The shutdown operation is simple, without complex preheating or cooling processes. The equipment has a wide load adjustment range, which can be flexibly adjusted between 30%-110% according to the actual oxygen demand. Whether it is stable oxygen supply for continuous production or dynamic adaptation for intermittent production, it can accurately match to avoid oxygen waste.
3. Compact Floor Space, Significantly Reducing Infrastructure Investment
Compared with the huge workshop demand and complex infrastructure projects of cryogenic air separation equipment, VPSA oxygen generation equipment has a compact structure and high integration, occupying only 1/5-1/3 of the area of traditional equipment. It does not require special low-temperature storage tanks and pipelines, and can be installed near the production workshop to reduce oxygen loss during transportation and pipeline investment. It is especially suitable for small and medium-sized enterprises with limited space or old factory renovation projects.
4. Safe and Stable, Operation and Maintenance Costs Negligible
VPSA oxygen generation equipment adopts a non-low temperature and non-high pressure operation mode, avoiding the safety risks in the storage and transportation of liquid oxygen. The equipment operating temperature is stable in the normal temperature range, and the failure rate is extremely low. The service life of the core component molecular sieve is as long as 8-10 years. Daily operation and maintenance only need to regularly check filters and valves, without the need for professional technical teams to be on duty, which greatly reduces the enterprise’s operation and maintenance manpower and cost investment.
As a leader in VPSA oxygen generation technology, Jiangsu Minnuo Group has achieved three major breakthroughs in core technologies through continuous technological iteration and innovation: first, the independently developed high-efficiency molecular sieve adsorbent, which increases the adsorption capacity by 20% and improves the oxygen purification efficiency; second, the optimized process flow design, which reduces equipment resistance loss and further reduces energy consumption by 15%; third, the integrated application of intelligent control systems, realizing real-time monitoring, data tracing and remote diagnosis of equipment operation status, making oxygen supply management more intelligent and worry-free.
II. Global Coverage: Diversified Application Scenarios of VPSA Oxygen Generation Equipment
