Cryogenic oxygen plant is used for producing oxygen for industrial and medical applications. Cryogenic distillation technology is used in the manufacturing and fabricating of plant machinery. For getting high quality liquid oxygen, you must use liquid oxygen plant that takes oxygen from the atmospheric oxygen which is then cooled until it gets liquefied. After this stage, oxygen is distilled at its boiling point of -183 degree Celsius. This technique is used for generating industrial gases such as oxygen, nitrogen and argon. Cryogenic distillation process was pioneered by Carl Von Linde in 1930s and is still being widely used throughout the globe. It is ideal for generating high purity oxygen. High quality materials are used in the manufacturing and fabricating that meet the standards of American Society of Mechanical Engineers (ASME) standards.
Salient features of cryogenic oxygen plant –
- Advanced cryogenic distillation technology
- Sturdy designing
- Fully or semi-automated control as per customer requirements
- Low operational cost
- Low maintenance cost
For ensuring smooth working of cryogenic oxygen plant machinery, it is imperative for tight integration of heat exchangers and air separation columns for maintaining efficiency. Energy for cooling oxygen to cryogenic temperature is obtained by the compression of the air. In order to get low distillation temperatures cryogenic oxygen plant needs a refrigeration cycle and cold equipment that must be placed within a insulated closure which is commonly known as cold box. However, for getting energy to run refrigeration cycle the latest liquid oxygen plants use expansion turbines. When the air is compressed, it is passed through a cleanup system where vapor, carbon dioxide and hydrocarbons are eliminated. Afterwards, the compressed air is passed into high pressure distillation column where vaporous oxygen is formed at the top of the column and nitrogen is formed at the bottom of the column.
