Study Notes
Nitrogen in Food Preservation
- Nitrogen is used to preserve packaged food by displacing oxygen, which prevents the growth of microorganisms and spoilage.
Industrial Gases Applications
- Industrial gases are commonly used in their solid or liquid state in applications such as refrigeration, cryogenic preservation, and welding.
Cryogenic Technology
- Cryogenic technology refers to the production and use of extreme cold at temperatures below -100°C.
Modern Engineering Division
- Cryogenic engineering is a new division of engineering that has arisen with the modern expansion of industry.
Cryogenic Techniques Advancements
- New cryogenic techniques have been developed to reduce and improve the cost and efficiency of cryogenic processes, such as liquefaction and gasification.
