A mixture contains 20mol% water, 30mol% 1-propanol, and 50mol% methanol flows at 100kmol/hr at temperature of 75C and 15 bar. Use ASPEN PLUS to answer the following questions. In all cases, use NRTL-RK as the property method. A) The mixture is flashed to 1 bar, where the vapor is separated from the liquid. The flash tank operates at 1 bar and 75C. (50 marks) The flow rate of components in the vapor phase is Water:1-propanol:Methanol:kmol/hrkmol/hrkmol/hr B) Use Design Spec to define the flow rate of methanol in the vapor phase to be 400.1kmol/hr by changing the temperature of the block. The results of Design Spec shows that the Temperature is C and the flowrate of methanol in vapor phase is kmol/hr
