1. Consider A single-stage vaporization process is used to separate a feed stream (F) containing water (W) and three alcohols - methanol (M), ethanol (E), and isopropanol (I) - into two product streams, a vapor (V) and a liquid (L). The feed flowrate is 100kmol/h, and the mole fractions of components are: xW=0.40,xM=0.25,xE=0.15, and xI=0.20. In the feed stream, the substances have the following molar enthalpies: water, 5.2kJ/mol; methanol, 4.3kJ/mol; ethanol, 4.4kJ/mol; isopropanol, 4.8kJ/mol. a. Given that the flowrate of the liquid stream is 1.25 times that of the vapor stream, calculate the total flow rate of each stream. b. The product streams have the following total molar enthalpies V:6.9kJ/mol;L:5.9 kJ/mol. Calculate the rate at which thermal energy must be added to the process (Q). c. The vapor product stream has a composition as follows: yW=0.20,yM=0.35,yE=0.30, yI=0.15. Calculate the composition of the liquid stream and K-values of components
