cryogenic fractionation → kriogena frakcinacija
Cryogenic fractionation is a process of separation of gases by cooling them until they enter their liquid state. Large scale gas production companies use this method to produce liquid oxygen, liquid nitrogen etc. Gases have different boiling points (the temperature at which they change from liquid to gas). Oxygen has a boiling point of -183 °C, and nitrogen a boiling point of -195.8 °C. Therefore by cooling the gas mixture to -183 °C, the oxygen can be collected as liquid and the nitrogen remains its gaseous form.
cryogenic fluid → kriogenski fluid
Cryogenic fluids are used for accessing low temperatures, usually below -150 °C. Cryogenic temperatures are achieved by the rapid evaporation of volatile liquids. The most common laboratory cryogenic fluids are liquid nitrogen (-196 °C). Nitrogen gas is colorless and odorless. The cloud formed when pouring liquid nitrogen is condensed water vapour from the air, not nitrogen gas.
