Explain the isolation of nitrogen and oxygen from air.
Answers
Answer:
The process used in air-separation plants is cryogenic distillation. It is a four-step process that cools atmospheric air to extremely low temperatures. When cooled like this, the component gases are then isolated, separated and collected. Some plants are set up to also harvest the liquid forms of nitrogen or oxygen.
Answer:
Air is freed from water vapour and carbon dioxide bypassing it through a dehydrating agent and caustic potash. It is subjected to high pressure and cooling after repeated compression and cooling. Air is converted into a liquid. When temperature rised first nitrogen boils at -196 degree Celsius and is converted to gaseous Nitrogen gas when the temperature rises -183 degree Celsius, oxygen also boils to give out gaseous oxygen. Thus Nitrogen Oxygen can be separated by fractional distillation.
