There are many benefits of cryogenic based oxygen nitrogen plants. We will discuss them one by one. Firstly, you must understand cryogenic distillation is the best methodology for air separation. Industries prefer to use only the cryogenic extraction.
There are other technologies also such as pressure swing adsorption and membrane. These techniques are good but do not match the effectiveness and quality of cryogenic distillation. Only cryogenic process can produce oxygen and nitrogen on large scale with high purity.
PSA methodology can fulfill the requirements of small and micro businesses. The PSA oxygen generator plants can generate oxygen in small volume with low purity. PSA systems operate on adsorption process that uses adsorbing materials like Zeolite adsorbent. In this process, Zeolite molecular sieves adsorb more than the others. Oxygen passes through while nitrogen is adsorbed.
Amongst the benefits, you cannot ignore the efficiency and reliability of delivering uninterrupted supply of oxygen, nitrogen and with some modifications argon via fractional distillation. Industries and hospitals prefer cryogenic production because you can store cryogenic liquids at low pressure.
Many customers wonder why cryogenic plants are pricier than the PSA generator plants. They get confused since both produce oxygen but their prices are so different. To clear their doubts, they use differently technologies. PSA uses simple technologies with simple and low priced components.
On the other hand, cryogenic air separation unit uses cutting-edge technology with many elaborate processes using high quality components and parts. The process can generate only oxygen or nitrogen in both liquid and gaseous form. This is the reason why air separation plants costlier than PSA oxygen plant.
The Air Separation Unit remains a key piece of equipment across a wide range of applications and industries.
As the growing demand for industrial gasses continues to increase, the ASU provides a reliable and efficient method for producing these gasses at the required purity levels. At the same time, the air separation process offers a cost-effective means of producing high-purity gasses compared to other methods, generating them in large quantities, leading to economies of scale and reduced per-unit production costs over time.
But what exactly is an Air Separation Unit, how does it work and what are its key applications? Here's a guide to the ASU, written from our experience in cryogenic engineering and design and manufacture of these structures.
An Air Separation Unit (ASU) is an industrial facility used to separate atmospheric air into its primary components (namely nitrogen, oxygen, and, in some cases, argon and other rare gasses). These units are typically composed of elements such as air compressors, an air purification system, heat exchangers, cryogenic cooling systems and distillation columns, among others.

While there are various methods that can be performed by an Air Separation Unit, fractional distillation is the primary separation technique employed.
The main working principle behind an ASU is the separation of air via its liquefying and distilling processes. A simplified overview of how an ASU typically operates looks like this:
As the air ascends the column, it is gradually warmed, and different components evaporate at their respective boiling points. For instance, oxygen-rich vapor rises to the top of the column, while nitrogen-rich liquid collects at the bottom. The argon, if present, is usually extracted as a side product at an intermediate point in the column.
Across these operations, it's key for the Air Separation Unit to operate presenting a very tight integration of heat exchangers and separation columns, ensuring its efficiency.
