Question: you have a stream of 250 gs of a liquid...

Question details

You have a stream of 250 g/s of a liquid mixture containing 50 wt% n- propyl propionate and 50 wt% n-propanol. You will be extracting the n-propanol using pure DES. The final propyl propionate-rich stream is to contain no more than 10 wt% n-propanol. All streams are at 293K.

293K Data from Samarov et al All values are wt% Л 100 n-propanol 2080 30 40 60 0 50 60 40 70 30 20 DES 90 10 100 10 20 30 40 50 60 70 80 90 100 n-propyl propionate

(a) What S/F ratio is required to achieve this separation in a single equilibrium stage? What is the split fraction of propyl-propionate with this design?
(b) What S/F ratio is the minimum feasible amount to achieve this separation? What is the split fraction of propyl-propionate with this design?

(c) How many equilibrium stages are required to achieve the desired separation using an S/F ratio of 2.35?
