Cryogenic Oxygen Production Plant

Basic Principle

Our Cryogenic Oxygen Production Plant taps oxygen and nitrogen from the atmosphere air. The feed air is entered into the molecular sieve purification system to separate the moisture and CO2 from the process air. Subsequently, it is liquefied by cryogenic cooling using the latest plate and fin, high efficiency heat exchangers and expanders. The liquid air gets separated into oxygen and inert gases in the air separation column. Liquid oxygen is stored in a liquid storage tank.

There are some special features of our Cryogenic Oxygen Production Plant. As following:

Compressor

Cryogenic Oxygen Production Plant should use Oil free rotary screw / centrifugal oil compressor, working between 0.6 and 1.0 mpa.

Exchangers & Columns

Cryogenic Oxygen Production Plant should use Aluminum Brazed exchangers and packed columns for high efficiency.

Turbo Expanders

Cryogenic Oxygen Production Plant should use turbo expanders (Oil or Air Bearing) for trouble free operation.

PLC

Cryogenic Oxygen Production Plant above "500NM3/H" are supplied with automatic PLC control.
