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.
