Cryogenic Oxygen Nitrogen Gas Plant

Cryogenic Oxygen Nitrogen Gas Plant

1.Design principle of this plant is based on the different boiling point of each gas in the air. Air is compressed, precooled and got removal of H2O and CO2, then to be cooled in the main heat exchanger until it is liquified. After rectification,production oxygen and nitrogen can be collected. 2. This plant is of MS purification of air with boosting turbine expander process. It is a common air separation plant, which adopts complete stuff filling and rectification for argon making. 3. Raw air goes to air filter for removal of dust and mechanical impurity and enters air turbine compressor where air is compressed to 0.59MPaA. Then it goes into air precooling system, where air is cooled to 17 ℃. After that, it flows to 2 molecular sieve adsorbing tank, which are running in turn, to be got removal of H2O, CO2 and C2H2.

Cryogenic Nitrogen Gas Generator


     Our Cryogenic Oxygen Nitrogen Gas Plant is an integrated industrial system designed for simultaneous production of high-purity gaseous oxygen and gaseous nitrogen via advanced cryogenic air separation technology. Tailored for medium-to-large-scale dual-gas demands, it delivers oxygen purity and nitrogen purity of 99.99%–99.9999%, with a combined production capacity of 300–3,000 Nm³/h .

The plant integrates core modules: high-pressure air compressors, multi-stage air pretreatment, cryogenic heat exchangers, dual-distillation columns , and dedicated gas storage buffers. Constructed with low-temperature-resistant 304/316 stainless steel and aluminum alloy, it meets CE, ISO 9001, and GB 50030 certifications. Equipped with a semi-automatic PLC control system, it supports 24/7 continuous operation with optimized energy consumption and ensures stable performance even in fluctuating ambient temperatures.

Working Principle

 product-1035-791

The basic principle of air separation is use cryogenic rectification to condense air into liquid and separate the air according to the evaporation temperature of each component,The two-stage rectification tower simultaneously obtains pure nitrogen and pure oxygen at the top and bottom of the upper tower.It's also possible to take out liquid oxygen and liquid nitrogen from the evaporation side and the condensation side of the main cooling respectively.

 

Application Areas​

1.Metal processing: Supplies oxygen for oxy-fuel cutting/welding of steel and nitrogen as a shielding gas for stainless steel welding, preventing oxidation and improving weld quality.​
2.Electronics manufacturing: Delivers high-purity nitrogen (99.9999%) for semiconductor wafer cooling and oxygen (99.99%) for thin-film deposition, ensuring component precision.​
3.Chemical & petrochemical industry: Uses oxygen for oxidation reactions and nitrogen for inert blanketing of storage tanks, preventing flammable gas ignition.​
4.Food & beverage sector: Applies nitrogen for modified atmosphere packaging of snacks/meat and oxygen for aerobic fermentation in beer/wine production, complying with FDA standards.​
5.Medical & healthcare: Produces medical-grade oxygen for hospital pipelines and high-purity nitrogen for medical device sterilization .​
6.Energy sector: Supports coal gasification and power transformer cooling , enhancing energy efficiency and equipment lifespan.
