Working Principle Of Oxygen Gas Manufacturing Plant

Oxygen Gas Manufacturing Plant usually uses oxygen in the air, separates and purifies it, and finally obtains a high-purity oxygen supply. The working principle is based on air separation technology, one of the common methods is to use molecular sieve or condensation technology. Here's how it works:

Molecular sieve adsorption method:
Absorption and separation of air: The original step involves passing air through a molecular sieve adsorption device. The pores in the molecular sieve selectively adsorb nitrogen and other impurity gases, while oxygen is left behind.

Adsorption and desorption process: When air passes through the molecular sieve, nitrogen and other gases are adsorbed onto the molecular sieve, while oxygen passes through and is collected. Desorption, through changes in pressure or other methods such as temperature changes, then releases nitrogen and other gases from the molecular sieve, creating an oxygen-rich fluid.

Condensation method:
Condensation and separation of air: Another method is to separate the liquid air into nitrogen and oxygen by cooling the air and condensing it into a liquid, then using the difference in its boiling point. Oxygen has a lower boiling point in liquid air, so it can be evaporated and collected by adjusting the temperature.

Separating oxygen from liquid air: The liquid air is heated to evaporate it, and then the resulting gas is passed through a separation step to separate oxygen from other gases, and finally collect high-purity oxygen.

Precautions:

Quality Control: Strict quality control and monitoring of the oxygen produced ensures it meets medical or industrial standards.

Safety measures: During the entire separation and purification process, strict safety regulations and operating procedures need to be followed to ensure the safety of production facilities and operators.

Regular maintenance and cleaning: Perform regular maintenance and cleaning of gas manufacturing equipment to ensure proper operation of the equipment and high purity of oxygen.

The working principle of the oxygen gas manufacturing plant is based on air separation technology. By selectively separating oxygen and other gases, high-purity oxygen is finally obtained to meet the needs of medical, industrial and other fields.
