Distillation - Definition Detailed Process Types Uses

For example, the boiling point of water at sea level is 100 o C but its boiling point at an altitude of 1905 meters is 93.4 o C (since the atmospheric pressure is relatively lower at high altitudes). For a mixture of liquids, the distillation process is dependent on Dalton’s law and Raoult’s law .

Azeotropic_distillation

For the distillation of ethanol for gasoline addition, the most common means of breaking the azeotrope is the use of molecular sieves. Ethanol is distilled to 96%, then run over a molecular sieve which absorbs water from the mixture. The concentration is now above 96% and can be further distilled. The sieve is heated to remove the water and reused.
