Liquid Industrial Oxygen refers to oxygen that has been liquefied and is used in various industrial applications. Its availability in liquid form provides advantages in storage and transportation, making it a preferred choice for certain industrial processes.ï This is typically produced through the process of cryogenic distillation, which involves cooling and compressing gaseous oxygen until it liquefies at temperatures below -183C (-297F). Liquid Industrial Oxygen is used in various metal production processes, including steelmaking and metal cutting, where it serves as an oxidizer or as a fuel in oxy-fuel combustion processes.
