Consider the Linde liquefaction process of Oxygen. We want 10 kg/min of liquid oxygen. Each stage of the two-stage compressor has an isentropic efficiency of 85%. You may assume that 1 atm is approximately 1 bar. Calculated the PVT and the thermal properties of oxygen using Peng-Robinson EOS. The critical properties of Oxygen are:

Tc = 154.58 K; Pc = 50.43 bar; = 0.022

*(ideal)/ = 3.63 (1.794 10^(3))* + (0.658 10^(5))*^2 (0.601 10^(8))*^3 + (0.179 10^(11))*^4

Where T is expressed in K.

USE ASPEN PLUS TO SOLVE THESE PROBLEMS!

a) Calculate the actual work required in both stages.

b) Calculate the unknown temperatures T3, T5, and T7

c) Calculate the heat removed from heat exchangers B and C

You dont need to know the formula if you do it on Aspen Plus, which I am askinf you to do.
