Separation of Air Components (Air Separation Plant or AS Plant) is a process that captures the basic components of air which are Nitrogen, Oxygen, and Argon, through separation processes. Air separation is ideal for airline companies, for a wide range of different industrial and commercial uses.

By separating or removing atmospheric air into its component parts, Air Separation Plants can produce several other by-products including Carbon Dioxide, Hydrogen (H 2 ), Helium, and Dry Ice.

Depending on the main process gas used, these processes for production are known as the dry route or the amine route. On average, 50.9% of air consists of nitrogen, 0.93% contains argon, and 0.038% is made up of oxygen with an additional 0.93% being carbon dioxide and trace amounts of other gases.

When forming a component by component mixture with air, these components are known as air products. The main air products used commercially include nitrogen which is produced as a component of air; oxygen which is predominantly produced using air separation; argon which is mainly obtained using a wet process; de-mineralized (demineralized) water; and carbon monoxide which is produced directly by burning natural gas in the presence of steam at high temperature (traditionally part of the manufacture of coke).

The Air Separation plants could be custom-designed to meet the specific requirements of the customer. It range in size from small plants that can produce 250,000 cubic feet per day (cf/d) of high purity oxygen to large multistage plants producing more than 11,000,000 cf/d of oxygen. Regardless of size, all plants use the same separation method that utilises chilled ammonia as a process fluid.

The technology for separating air evolved in the mid 19th century with the invention of the first industrial scale Air Separation plant by French engineer, Paul Deléage. His process uses a double compression sequence on air to extract the most air possible from mixtures of gases.

Bhartiya Cryogas is a well-known air separation plant manufacturer and exporter in India. Air separation plants include Nitrogen Plant, Oxygen Plant, Compressor, Water Cooler etc. The company supplies technologically advanced Air Separation Plants and Cryogenic air separation plants for Oxygen, Nitrogen, Argon. It has designed and supplied a complete range of Air Separation Plants for our domestic clients in the Indian market and are exporting Air Separation Plants to Saudi Arabia, Middle East, Asia and Africa.

The Air Separation Plant (ASP) is one of Cryogas' specialties. The plant uses cryogenic technology to produce Nitrogen and Oxygen, both primarily used in GAS applications. ASP's are used by large industrial and power plants for producing process gases for use in boilers, turbines, and other power generating equipment. These process gases are produced from air in the range of gaseous purity from 99.95% N2+O2 to 99.99% N2 or O2 by blending the incoming air with lower purity synthesis gas obtained from a syngas generator feeding steam methane reformer, at low pressure (1-150 psig) provided by a condensing steam reforming unit, with cryogenic separation necessarily taking place at ambient temperature and pressure (0-60 psig).
