A schematic of the typical refrigeration process ...


Liquid nitrogen—formerly a by-product of the process—is now a product in its own right, being used principally as a convenient source of refrigeration, especially in the frozen food industry. The other important by-product of air separation is liquid argon, which again can be produced at a very high purity.

Air Separation into Oxygen, Nitrogen, and Argon

This process requires very complicated heat integration techniques because the only heat sink for cooling or condensation is another cryogenic stream in the process. E-201 uses liquid nitrogen produced in the plant. E-203 and E-206 can use liquid nitrogen from the plant or cold nitrogen from Stream 13. These are not shown in the PFD. Equipment ...

Commercially, ammonia is made by combining free nitrogen and hydrogen gases under high pressure and temperature in the presence of a catalyst. The process most commonly used is the Harber-Bosch method. Anhydrous ammonia is the liquid form of pure ammonia gas, technically water-free, and the substance used universally as an industrial refrigerant.

Designing and Analysis of Cryogenic Storage Vessels

top to bottom. During this flow the evaporation of nitrogen and other gases takes place and only oxygen is collected in bottom reservoirs. The liquid nitrogen is produced at the top of the column. Due to this gaseous nitrogen can be liquefied by giving the heat energy to the liquid oxygen. Here the liquid oxygen is evaporated.

Industrial Oxygen: Its Use and Generation

The idea behind the process is to lower the temperature of the air such that nitrogen and oxygen separate based on their boiling points. This occurs at around - 300oF.. If higher purity oxygen or liquid oxygen is required, further distillation is required. For liquid oxygen, nitrogen is used as the heat transfer fluid to further cool the oxygen.

Freezing of fruits and vegetables

Finally, the liquid-gas mixture flows through the evaporator where it is converted into a saturated vapor state and removes heat from the environment in the process of cooling. With this last stage the loop restarts again. The other refrigeration system employed by the food industry is the cryogenic system with carbon dioxide or liquid nitrogen.
