Question:

Cygnarowicz and Seider [Ind. Eng. Chem. Res., 28, 1497-1503 (1989)] present a process design for the supercritical extraction of β-acetone from water with carbon dioxide using the GC-EOS method of Skjold-Jorgensen to estimate phase equilibria. Repeat the calculations for the conditions of their design using the Peng-Robinson EOS with the Wong-Sandler mixing rules. How do the two designs compare?
