As an qualified air separation equipment manufacturer with more than 15 years of experience, CANGAS developed the oxygen and nitrogen generation plants by cryogenic technology at the begining of 2014.


Cryogenics, a branch of low-temperature physics concerned with the effects of very low temperatures, was first investigated by Michael Faraday, who demonstrated that gases could be liquefied leading to the production of low temperatures of around 173 K. Cryogenic technology gained widespread recognition during the 1960s, with emphasis on cryogenic techniques, cooling system installation configurations, and applications. With various applications of cryogenic technology in earlier commercial and industrial systems, the critical design issues and the operational aspect of cryogenic systems, with an emphasis on cost and reliability, is apparently important. We are aware of the significant performance improvements in devices, components, and systems due to the integration of cryogenic technology, with major emphasis on reliability, affordability, and availability. Cryogenic technology for the production of inert gases for industrial, commercial, and military applications is the the main field that we are working on.

CANGAS® low pressure twin-tower cryogenic oxygen and nitrogen generation plant

For CanGas® twin-tower cryogenic oxygen and nitrogen generation plant, the working pressure of the whole system is less than 0.7Mpa. Operation is simple, flexible and safe while energy consumption is very low.

  The main parts are air compressor, air dryer (pre-cooler), online filters, molecular sieve adsorption towers for pre-treatment, recycling cooling water system, gas bearing expander, positive flow expansion and refrigeration as well as twin-tower distillation. The overall extraction rate is high. High purity oxygen and nitrogen can be produced at the same time. Certain amount of liquid Argon can also be produced at the same time (optional). The output of gaseous oxygen production could be from 50Nm3/h to 60000Nm3/h @ purity of above 99.6% and nitrogen purity is above 99.99%. The plant can be designed according to customers’ specific requirements. The capacity and purity could be insured with low energy consumption.

Note

Nm3/h is the flow unit for gaseous gases at 0℃, 101.325KPa. The pressure refers to gauge pressure. Same below. The operational cycle time of the plants is 12 months, but it is suggested to heat the plant once at lest every 6 months.

These are for reference only. Specific items need to be confirmed. Same below.
