Consider a device to separate the components of synthesis gas (mixture of H2 and CO). The molar

fraction of CO is denoted by y and varies between 0.05 and 0.5. The mixture enters the device at

200 m3 s-1, 100 ◦C and 20 bar. The separated components exit at 100 ◦C and 20 bar.

Questions:

(a) Compute the minimum theoretical rate of work Pmin to be supplied to the device as a function

of y. Hint: use the Gibbs function.

(b) Plot Pmin as a function of y.
