INDUSTRIAL GASES

Industrial cryogenic gases are gases produced on an industrial scale and widely used across manufacturing, energy, medical, scientific and research sectors. The most common cryogenic industrial gases include liquid nitrogen (LIN), liquid argon (LAR), liquid oxygen (LOX), liquefied natural gas (LNG) and carbon dioxide (CO₂).

These gases are stored and handled at extremely low temperatures in liquid form, allowing high storage density and efficient transportation. Due to their cryogenic nature, their production, storage and distribution require specialized cryogenic equipment, advanced thermal insulation and strict safety standards.

Production of Industrial Gases – Air Separation Units (ASU)

Most industrial cryogenic gases such as nitrogen, oxygen and argon are produced in Air Separation Units (ASU).
An ASU is an industrial facility that separates atmospheric air into its main components through compression, cryogenic cooling and fractional distillation, delivering high-purity gases in liquid or gaseous form.

ASUs are critical installations where thermal efficiency, vacuum integrity and reliable cryogenic systems are essential for continuous and cost-effective operation.

Transportation and Storage of Cryogenic Gases

After production, industrial cryogenic gases are transported and stored using:

• Cryogenic storage tanks

• Dewars and portable cryogenic vessels

• Vacuum insulated piping (VIP)

• Cryogenic tankers and trailers

Vacuum insulation plays a key role in minimizing heat transfer, reducing boil-off losses and ensuring safe and efficient operation. Any degradation of vacuum insulation directly impacts energy consumption, system performance and operational costs.
