Top Best Quality Liquid Oxygen Plant Oxygen Filling Station CE
1. Air compressors: The air is compressed to 0.5Mpa-0.7Mpa by the
2. Pre-cooling: The air in the pre-cooling unit is pre-cooled to
5°C -10°C, 3. Purification: The remaining water, carbon dioxide and
hydrocarbons in the air are removed from the purified air of the
4. Air expansion: The air undergoes expansion refrigeration in the
expander to provide the cooling capacity required by the device.
5. Heat exchanger: the aluminum plate fin heat exchanger has light
weight and high heat transfer efficiency.
6. Sub-cooling: Liquid air and liquid nitrogen are cooled by the
nitrogen and impure nitrogen in the sub-cooler.
7. Distillation: the air is subjected to distillation separation in
the lower tower, product nitrogen is obtained in the upper tower,
and product oxygen is obtained at the bottom of the upper tower.
1. Liquid Oxygen Plant - Air Separation Plant Process:
An Liquid Oxygen Plant air separation plant separates atmospheric
air into its primary components, typically nitrogen and oxygen, and sometimes also argon and other rare inert gases.
a. Purifying air by molecular sieve adsorption makes the process
simple, start-up and operation easy and safe, switch-over loss
small and rectifying condition stable.
b. By using the pre-cooling system to cool the air with normal temp.
Thus it makes the molecular sieve adsorbent in good condition.
c. For the use of the automatically controlled filter, the air
bearings turbo-expander and the aluminum
plate-fin heat exchanger, the stability, safety and reliability of
the whole plant are improved greatly.
d. By using a new construction of the evaporator-condenser to avoid
the accumulation of C-H chemical compounds.
