Full Liquid Air Separation Plant & Gas Liquefier

Full liquid air separation plant requires more cooling capacity than air separation plant. According to different production requirements, cycle compressor refrigeration, high and low temperature pressurized booster expansion refrigeration, low temperature pre-cooling unit and other processes are adopted to reduce energy consumption effectively. The related control system adopts DCS computer control system or PLC control system, and part of the on-site indication, so that the whole set of equipment can achieve the purpose of simple operation, stability and reliability. In order to reduce energy consumption, it is also possible to recover vaporization cold energy such as LNG/liquid nitrogen/liquid oxygen/liquid argon to make liquid air separation plant or liquefaction process. 
Moreover, our experienced technical team will propose the most economical solutions that best meet your requirements. Furthermore, the O2 and N2 yield can either be gas or liquor. Most of all, when the output is large enough, you will consequently get the highly profitable by-product-argon gas or liquid argon.

Since establishment, we designed and produced more than almost 20 different sets of air separation plants. Especially relevant, they all feature reasonable workmanship and small power consumption, high efficiency, and stable performance.Note: Those two pictures show the site of the project which delivered by Greenfir.
 
In addition, pressure is customized as required.

Therefore, if you need a set of air separation plant, maybe you can probably tell us your specific requirements and environmental parameters so that we can make professional quotations accordingly.
Please advise:
1. First of all, altitude, temperatures (highest temperature in summer and lowest temperature in winter) and humidity, earthquake intensity and wind speed;
2. Moreover, voltage including high voltage and low voltage;
3. In addition, your requirements on the output and purity of liquid oxygen or oxygen gas that are as indicated below:
