Consider a process with two sequential flash operations as shown below. The feed stream is at 100 °C, 3.8MPa. It consists of hydrogen-185 kmol/h, methane-45 kmol/h, benzene-45 kmol/h, toluene-5 kmol/h.The

first flash column is operated at 100 °C with no pressure drop. The second flash column is operated adiabatically at 0.1 MPa pressure. Please select K and H value methods both as Peng-Robinson. a. What is the temperature of flash column 2? b. What are the molar fractions in the liquid product coming out of flash column 2? (Hint: you can set upstream molar fractions report)
