Product Description
VPSA Oxygen Generator (Vacuum Pressure Swing Adsorption Oxygen
Systems) is a large-scale industrial oxygen supply equipment based
on Vacuum Pressure Swing Adsorption (VPSA) technology. It rapidly
produces high-purity oxygen by selectively adsorbing nitrogen from
air through lithium-based molecular sieves. It boasts core
advantages such as fast start-up (reaches the standard within 20-30
minutes), stable continuous operation, low energy consumption, and
convenient maintenance. Without the need for chemical reagents or
complex refrigeration systems, it can adapt to the harsh
requirements of high-temperature, high-load industrial scenarios
such as steel smelting. As a core type of Industrial Oxygen
Generator, the modular design of the VPSA Oxygen Generator supports
on-demand capacity expansion. Its large flow output of 1000Nm³/h
fully matches the continuous oxygen supply needs of large steel
plants, and the 93% purity is the golden standard for
oxygen-enriched combustion in steel smelting, which can not only
improve combustion efficiency but also control production costs.

I. Why is VPSA Oxygen Generator the First Choice for Steel
Smelting?
In the steel smelting process, the oxidation reactions and
oxygen-enriched combustion in converters and blast furnaces require
continuous and large-flow oxygen supply. The purity and stability
of oxygen directly affect smelting efficiency, molten steel
quality, and energy consumption costs. Traditional cryogenic oxygen
generators occupy a large area, have a long start-up time (several
hours to dozens of hours), and are complex to maintain. However,
the VPSA Oxygen Generator with 1000Nm³/h flow and 93% purity
perfectly addresses these pain points.
A purity of 93% is the optimal choice for steel smelting: a purity
lower than 90% will lead to insufficient combustion, increasing
energy consumption and pollutant emissions; a purity higher than
95% will significantly increase equipment costs, with diminishing
marginal effects on improving smelting efficiency. By precisely
controlling the adsorption-desorption cycle, the VPSA Oxygen
Generator stably outputs oxygen with 93%±2% purity, fully meeting
the oxygen-enriched blowing needs of converter steelmaking. It can
increase molten steel output by 15-20% and reduce the energy
consumption per ton of steel by 8-12%.
As the flagship model of vpsa oxygen generator, the equipment’s
1000Nm³/h flow fully matches the oxygen supply needs of a single
converter in large steel plants. If multiple furnaces operate
simultaneously, the capacity can be expanded to 2000-5000Nm³/h
through modular combination. Its low energy consumption performance
of 0.4kWh/Nm³ saves more than 30% of electricity costs compared
with traditional cryogenic oxygen generators. Calculated based on
8000 hours of annual operation, it can save millions of yuan in
electricity costs each year, significantly reducing psa oxygen
plant cost.
III. Procurement Key Points: How Do Steel Enterprises Choose
Cost-Effective Equipment?
For procurement teams of steel enterprises, selecting a VPSA Oxygen
Generator needs to focus on three core dimensions: parameter
matching, supplier strength, and after-sales support. In terms of
parameters, it is necessary to confirm whether the flow rate
matches the production capacity of the converter/blast furnace
(1000Nm³/h is suitable for 100-ton converters), whether the energy
consumption is lower than 0.45kWh/Nm³, and whether the purity is
stably around 93%. In terms of suppliers, priority should be given
to enterprises with psa oxygen plant manufacturer qualifications
and cooperative cases with large steel plants, ensuring that the
equipment has passed ISO9001 quality management system
certification and industrial product production licenses.
After-sales support is also crucial. The shutdown loss of steel
smelting equipment is huge, so it is necessary to select suppliers
that can provide 24-hour on-site service and timely supply of spare
parts (sufficient inventory of vulnerable parts such as molecular
sieves and valves). In addition, suppliers can be required to
provide customized solutions, such as optimizing the equipment
footprint according to the workshop layout and adjusting energy
consumption parameters according to the power grid load, to further
improve the equipment’s adaptability and economy.
With the advantages of large flow, low energy consumption, and high
stability, the VPSA Oxygen Generator has become the mainstream
oxygen supply equipment in the steel smelting industry. The
configuration of 1000Nm³/h flow and 93% purity accurately matches
the production needs of large steel plants. Its Vacuum Pressure
Swing Adsorption Oxygen Systems technology can not only improve
smelting efficiency and molten steel quality but also significantly
reduce operating costs, making it a key equipment for steel
enterprises to achieve energy conservation, consumption reduction,
quality improvement, and efficiency enhancement.
