Industrial Liquid Oxygen And Nitrogen Producing Plant
Description
Technical Parameters
● Production Capacity
Covers small to large scales: from dozens of m³/h (small units) to tens of thousands of m³/h (large facilities). Some models reach up to 100,000 m³/h for both oxygen and nitrogen, ensuring continuous supply for large industrial needs.
● Product Purity
Liquid oxygen purity up to 99.95% (meets metallurgy's efficient smelting needs); liquid nitrogen purity up to 99.9999% (fits electronics manufacturing's inert atmosphere requirements).
● Dual-State Output
Produces both gaseous and liquid oxygen/nitrogen:
Gaseous: For on-site use (e.g., power plant combustion, pipeline purging, food packaging).
Liquid: Easier for long-distance transport and storage (e.g., remote medical backup, biological cryopreservation, food rapid freezing).
work principle
Air Pretreatment & Compression
Ambient air is filtered to remove impurities, then compressed by multi-stage compressors (boosts pressure/temperature) for subsequent cooling.
Multi-Stage Cooling & Cryogenics Generation
Compressed hot air is cooled via heat exchangers; an expansion turbine (rapid pressure drop) generates cold energy to lower air to near-cryogenic levels.
Distillation Separation
Cooled air enters distillation columns: nitrogen (-196°C boiling point) evaporates and rises (collected as gas/liquid), oxygen (-183°C) stays liquid at column bottom (collected).
Product Collection & Cold Energy Recycling
Liquid oxygen/nitrogen are extracted for storage/processing; cold waste nitrogen pre-cools incoming air via heat exchangers to save energy.
NEWTEK is an expert in gas solutions
●Metallurgy:
Oxygen enables oxygen-enriched blowing in steelmaking; nitrogen purges molten metal and controls cooling during solidification.
●Chemical Industry:
Oxygen acts as an oxidant for reactions ; nitrogen serves as inert gas and carrier gas.
●Food and Beverage:
Liquid nitrogen rapidly freezes food; gaseous nitrogen displaces oxygen in packaging .
●Electronics:
Ultra-pure nitrogen creates inert environments for semiconductor manufacturing; oxygen aids etching and cleaning processes.
●Medical:
Liquid oxygen supports hospital oxygen supply; nitrogen is used in cryosurgery .
FAQ
1.What's the adjustable range of oxygen/nitrogen production capacity?
Covers small (dozens of m³/h) to large (tens of thousands of m³/h) scales, customizable to match industrial demand.
2.Can it meet the purity requirements of industries like electronics and metallurgy?
Yes-liquid oxygen up to 99.95% (metallurgy) and liquid nitrogen up to 99.9999% (electronics).
3.Does it have energy-saving designs to reduce operational costs?
Equipped with cold energy recycling (via waste nitrogen) and variable-load compressors, cutting energy consumption.
4.Can it produce both gaseous and liquid products for different application scenarios?
Yes-gaseous for on-site use (e.g., power plant combustion) and liquid for storage/remote transport (e.g., medical backup).
5.Is there after-sales support for installation, maintenance, and troubleshooting?
Provides full support: custom installation guidance, regular maintenance, and timely fault repair.
6.How long is the typical service life of the plant, and is there spare parts supply?
Average service life 15–20 years; stable spare parts supply ensures minimal downtime.
