Air Products Air Separation Unit

Product Introduction

Air products air separation unit is a gas separation equipment that liquefies, distills, and finally separates air into oxygen, nitrogen, and other useful gases. Its minimum operating temperature is 77K. At the end of the 19th century, air was still called "permanent gas". Later, people found that air can also be liquefied at deep low temperatures, and because of the different boiling points of oxygen and nitrogen, oxygen and nitrogen can be separated from liquefied air.

1. What is a small air separation unit?
A small air separation unit is a device used to separate different gases (such as oxygen, nitrogen, argon, etc.) from the air. It usually works through cryogenic fractionation or membrane separation technology, and is suitable for oxygen and nitrogen supply in medical, industrial, laboratory and other fields.

2. What is the working principle of a small air separation unit?
A small air separation unit liquefies the gas in the air by cooling the air to a low temperature. The liquefied gas is then separated by a distillation tower, and oxygen and nitrogen are separated according to their boiling points. By adjusting the operating conditions, oxygen, nitrogen or argon can be efficiently separated and purified.

3. What are its main applications?
Small air separation units are widely used in the following fields:

Medical industry: Provide high-purity oxygen supply to patients.
Electronic manufacturing: Provide pure nitrogen and oxygen for electronic product manufacturing.
Food packaging: Used for controlled atmosphere packaging to extend the shelf life of food.
Metal smelting: Provide nitrogen for metal processing and heat treatment processes.
