At its core, the operation of an air separation plant involves transforming air into its constituent parts. Let's break down the process, often referred to as "air separation plant design":
Compression
Atmospheric air enters the ASU and is compressed. Fortune Gas, an innovator in this field, employs a low-pressure process that reduces energy consumption.
Purification
Impurities such as moisture (H2O) and carbon dioxide (CO2) are removed using a Pre-Purification Unit (PPU). This ensures that only clean, filtered air enters the next stage.
Cooling
The purified air is cooled to cryogenic temperatures using advanced heat exchangers, bringing it to a state where components can be separated based on their unique boiling points.
Separation (Distillation)
Inside the "Cold Box," the core of an ASU, air components are separated through cryogenic distillation. For applications requiring advanced recovery, some systems are also capable of neon gas separation from ASUs, in addition to oxygen, nitrogen, and argon.
Air Separation Units are vital to numerous industries. Here’s a quick overview of their primary applications:
Metallurgy (e.g., Steel Making)
Oxygen supports combustion in blast furnaces to produce molten steel.
Chemical & Petrochemical
Nitrogen is used for inerting, purging, and transferring reactive chemicals, while oxygen powers combustion and oxidation reactions.

Q: What is the full form of ASU?
A: ASU stands for Air Separation Unit.
Q: What gases are produced by an ASU?
A: Common outputs include nitrogen, oxygen, and argon, while some systems also recover neon, krypton, and xenon.
Q: What is the difference between a Nitrogen Generator and an ASU?
A: Nitrogen generators typically produce nitrogen for small- to medium-scale applications with lower purity. In contrast, ASUs provide high-purity nitrogen and can also produce oxygen and argon.
Q: How much does an air separation unit cost?
A: Costs vary based on capacity, output purity, and design requirements. Contact Fortune Gas for tailored quotes.
