The oxygen plant supplies our production facilities with compressed air and air gases: oxygen, nitrogen, and inert gas (argon). These gases are vital for process intensification and high product quality. E. g., the purging of a molten bath with oxygen ensures higher temperatures, a significant acceleration of the carbon oxidation process, and the needed carbon content in stainless steel.

In addition, the Oxygen Plant production makes it possible to improve operation of the laser cutting equipment, to save electricity, for the inerting gas system inside a vacuum furnace, etc.

A cryogenic air separation unit ensures necessary gases by means of low-temperature rectification of liquefied air. The unit consists of compressor, process and auxiliary equipment.
Oxygen and nitrogen
The compressor increases the pressure of the atmospheric air injected. A built-in air filter and a separator clean the air from dust, mechanical impurities and condensed moisture.
Oxygen and nitrogen
The system of air pre-cooling of the vapor compression refrigerating machine provides air cooling by exchanging of the heat with the coolant that is circulating in the system. Passing the front-end purification unit the air gets rid of carbon dioxide, water vapor and hydrocarbons using the adsorption method.
Oxygen and nitrogen
A low-temperature unit creates the necessary conditions for the main technological processes of air separation and protects the equipment against environment exposure. To keep it simple, the process flow can be described as follows. The compressed air passes through purification units where moisture, carbon dioxide and hydrocarbons are removed.

Next, the air gets expanded in the expander with temperature decrease, then it goes through heat exchangers, gets liquefied, and finally it enters the distillation column for separation. This results in the production of liquid or gaseous argon depending on the mode.
Argon
The gaseous product is pumped to its destination via a pipeline. Liquefied gases are injected into the fixed cryogenic tanks or they are delivered to a desired point (including outside the plant) in special cryogenic tanks.
