Mass transfer operations tutorial 1

Mixtures of ethanol- methanol behave almost ideally at low pressures

A) For the pressures 1 and 10 bar abs given the appropriate Antoine equations calculate the X-Y- T data for this mixture

B) Plot the data as the isobaric bubble point and dew point curves for this mixture

C) Plot the vapour pressure curves for this mixture

D) Plot the X-Y equilibrium curve for this mixture ( use a 20 *20 cm grid)

E) Plot the composition relative volatility curve for this mixture

The Antoine equation is given below

The Antoine constants for each component are given in the table below these were sourced from the Dortmund database the constants give the pressure in mmHg abs and temperature in C

	A	B	C
ethanol	7.68117	1332.04	199.2
methanol	7.9701	1521.23	234
