1. What is an Air Separation Unit?
An Air Separation Unit (ASU) is an industrial facility used to separate atmospheric air into its main components (i.e. nitrogen, oxygen, and sometimes argon and other rare gases). These units usually consist of elements such as air compressors, air purification systems, heat exchangers, cryogenic cooling systems and distillation columns.
2. How does an Air Separation Unit work?
The main working principle of an ASU is to separate air through the process of liquefaction and distillation. Here is a brief overview of how an ASU generally operates:
Compression: At this stage, atmospheric air is drawn into the ASU and passed through a series of compressors to increase its pressure. The goal is to make the subsequent cooling and separation processes more efficient, with typical pressures ranging from 5 to 10 barg.
Purification: Before further processing, the compressed air is often purified to remove impurities (including moisture, carbon dioxide, or trace contaminants). This step ensures that the separated gas is of high purity and avoids problems such as freezing or plugging of cryogenic equipment.
Cooling: The now purified compressed air is cooled to cryogenic temperatures using a series of heat exchangers and refrigeration cycles. This causes the air to liquefy, as cryogenic distillation relies on differences in the boiling points of the various components.
Separation: The now cold, liquefied air is fed into a distillation column (or series of columns) so that the air is separated into its main components based on differences in boiling points:
Nitrogen has a lower boiling point (-196°C or -321°F) than oxygen (-183°C or -297°F).If separated, argon has a lower boiling point (-186°C or -303°F).
Collection, storage and transportation: The separated gas is collected and sent to storage tanks (pressurized tanks or cryogenic tanks). Then, depending on the purity requirements, the gas can be distributed and supplied to various industries and applications.
