What is the ideal work for the separation of an equimolar mixture of methan at 448.15 K (175°C) and 3 bar in a steady-flow process into product stream gases at 308.15 K (35°C) and 1 bar if T, = 300 K?

Prompt/Given Information: Consider a reversible isothermal expansion of vapor benzene at 450 K from 1 to 0.1 MPa. Assume that the PVT behavior of benzene obeys van der Waals equation of state.                                      P = (RT)/(V - b) - a/V2            for benzene: a = 1884514 (cm6 * MPa)/mol2 and                                  b = 119.47 cm3/mol For your convenience, at 450 K and 0.1 MPa the volume of vapor benzene is 37025 cm3/mol, and at 450 K and 1 MPa it is 3312.4 cm3/mol. R = 8.314 (MPa*cm3)/(mol*K). Note: 1 cm3*MPa/mol = 1 J/mol   Question: What is the change of internal energy? What would be the change of internal energy if the gas was ideal?

The vapor pressure of cyclohexane at 300 K is 0.14139 bar. What is the phase of cyclohexane at 310 K and 0.14139 bar? a) superheated vapor b) compressed liquid c) saturated vapor d) saturated liquid e) two-phase mixture f) We need more information.

5.20. Multistage stripper. A stripper at 50 psia with three equilibrium stages strips 1,000 kmol/h of liquid at 300°F with the following molar composition: 0.03% Cı, 0.22% C2, 1.82% C3, 4.47% nC4, 8.59% nC, 34.87% nCio. The stripping agent is 1,000 kmol/h of superheated steam at 300 F and 50 psia, Use the Kremser equation to estimate the com positions and flow rates of the stripped liquid and exiting rich gas Assume a K-value for Cio of 0.20 and that no steam is absorbed. Calculate the dew-point temperature of the exiting gas at 50 psia. If it is above 300°F, what can be done?
