What is an Industrial ASU plant?

An Industrial Air Separation Unit (ASU) plant is a facility designed to separate atmospheric air into its primary components, typically nitrogen, oxygen, and argon. These plants utilize the principle of fractional distillation of liquefied air to achieve the separation. ASU plants are crucial in various industries, including steel manufacturing, chemical processing, and electronics, due to their ability to provide high-purity gases.

1. Introduction to Industrial ASU Plants

Industrial ASU plants provide essential gases to numerous sectors. The typical unit starts with filtering and compressing air, which is then cooled to a liquefied state. The subsequent process of distillation separates the air into its components.

2. Components of an Industrial ASU Plant

Key components include air compressors, heat exchangers, distillation columns, and storage tanks. Each component is vital to the plant's operation. For instance, air compressors must handle pressures between 5 to 10 bar, while distillation columns operate at extremely low temperatures, around -196°C for nitrogen production.

3. Processes Involved in ASU Plants

An ASU plant typically involves three main processes:

  1. Compression: Air is compressed to approximately 6 bar.
  2. Cryogenic Distillation: The compressed air is cooled to a cryogenic state, often -185°C, to separate components based on boiling points.
  3. Purification: Gases are further purified, achieving up to 99.999% purity for oxygen and nitrogen.

4. Applications of ASU Plants

ASU plants serve various sectors:

  • Steel Industry: Oxygen is used for blast furnace processes.
  • Healthcare: ASUs supply medical-grade oxygen.
  • Electronics: Nitrogen is utilized for circuit board manufacturing.
