Industrial Cryogenic Oxygen Plant Oxygen Cylinder Filling Plant
With PLC Control
Two compression methods:
1) Internal compression air separation plants:
(low pressure liquid)-Liquid oxygen pump(pressurized liquid
oxygen)-oxygen vaporizer - oxygen cylinders
2) External compression air separation plants:
(low pressure gas)-oxygen storage-oxygen compressor(pressurized
The main technical specifications of internal compression
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.
