It can be observed from fig. It will actually be distilled to something slightly less like 965 the 965 alcohol is then sent to a distillation column that is under a different pressure one that pulls the azeotrope down maybe to 96.
1 that the mixture of ethanol and water shows significant change from 0885 to 0812 in azeotropic composition on changing pressure making it suitable for pressure swing distillation.
Pressure swing distillation ethanol water. Since the mixture is already above the 96 azeotrope. Ethanol can now be distilled up to 97. In the light of the azeotrope of ethyl acetate ethanol water a process of pressure swing distillation is proposed.
The ethanol water system has an azeotrope at 08943 mole fraction ethanol at 1 atm pressure see also principles of this section. Alternatively the composition of the azeotrope is dependent on pressure which can be exploited to get the mixture across the azeotrope. Ethanol and water form an azeotrope at approximately 955mol ethanol at 1 atm.
Indeed 782 0c is the minimum temperature at which any ethanolwater solution can boil at atmospheric pressure. Ethanol boils at 784 0c water boils at 100 0c but the azeotrope boils at 782 0c which is lower than either of its constituents. Pressure swing distillation is one such technique for ethanol separation.
The separation process is simulated by aspen plus and the effects of theoretical stage number reflux ratio and feed stage about the pressure swing distillation are optimized. If the pressure is reduced from 760 torr to 100 torr it is observed see fig1 that the composition of the azeotrope goes more and more to 1 to completely disappear at pressure below 70mmhg not visible in fig1. This is called pressure swing distillation.
This is a low boiling point or positive azeotrope.
