Air Separation Process
Have you ever wondered how it is possible to break down the air, impalpable and invisible by definition? Yet, every day The NUZHUO Group extracts oxygen, nitrogen and argon from the air.
The credit goes to Air Separation Units (ASUs), concentrated technology that takes advantage of the different states of matter (solid, liquid and gaseous) to separate the elements that make up the air we breathe.
Cryogenic air separation plants are particularly suitable for the production of liquid and/or gaseous oxygen (O2), nitrogen (N2) and argon (Ar). Air separation is based on the cryogenic rectification process, in which the air is cooled down to -196°C and partially liquefied. During rectification, the individual air components separate due to their different boiling points. Afterwards the gases / liquids are available in highest purity.
Cryogenic air separation process is an energy intensive, low-temperature process which separates air into its component gases. Energy consumption of oxygen separation is an increasing function of oxygen purity. The cost of electric energy is the largest single operating cost incurred in air separation plants. It is normally in the range of one third or two thirds of the operating costs associated with producing gas and liquid products. Since the steel industry uses extensively oxygen, nitrogen, and argon gases, the price of these gases affects the production cost of steel and steel products. The energy efficiency of ASP is considerably influenced by the production ratio of oxygen and nitrogen, which can be varied depending upon the requirement.

ASU Plant For Medical
For the generation of medical grade oxygen we offer two different solutions. We can build our PSA systems small enough to produce gaseous oxygen directly in the hospital. If you want to produce smaller amounts of oxygen, this is the right solution for you. If you want to produce a larger quantity of oxygen and need it in both gaseous and liquid form, then our cryogenic systems are the right choice for you. Both of our plant types can be delivered with cylinder filling stations. Each plant will be tailored to the specific needs of our clients. We will offer you full service during all project phases: planning, design, manufacturing, delivery, supervision, commissioning and start-up of the plant.
ASU Plant For Industries
The innovative solution concepts of NUZHUO are used in numerous manufacturing processes and industries. Our applications enable efficient, cost-effective, safe and environmentally friendly manufacturing processes and contribute to the improvement of product quality.
Oxygen (O 2), nitrogen (N 2) and argon (Ar) are of great importance in the metalworking industry. Oxygen is mainly used for oxyacetylene welding, flame cutting and laser cutting as well as for melting processes. Nitrogen is used in bright annealing processes and in liquid form in shrinking technologies. Argon is mainly used as an inert gas during welding, but also in metal melting technology.
In the chemical and petrochemical industry, oxygen (O 2) is used for a variety of oxidation processes. Nitrogen (N 2) is mainly used for inerting processes. As an inert gas (N 2) it is used for the safe storage of flammable liquids, as a protective gas during the annealing of metals and as a refrigerant in the cryogenic liquefied state (in industrial production).
