Unit operation - Wikipedia

Unit operation In chemical engineering and related fields, a unit operation is a basic step in a process Unit operations involve a physical change or chemical transformation such as separation, crystallization, evaporation, filtration, polymerization, isomerization, and other reactionsHistory and technological progress in the course of time,evaporator to form a heat exchanger unit is still used today History and technological progress of air separation Liquid N₂ Pure nitrogen Condenser Pure oxygen Process air Liquid with 35–40% O₂ Double column What are the principles of air separation? 15 bar 56 bar Low-pressure column Pressure column 07 Condenser 15 bar 56 bar History and technological progress of air separation The Air Separation Process – Unit Perspective - YouTube,2014-08-27 · How are gases such as oxygen or nitrogen obtained?
