A chemical polishing process requires acetone vapor at T = 95 [C]. The inlet stream to the vaporization unit is at T = 30 [C]. The entire process occurs at P = 1 atm and the heat is supplied with a steam driven heat exchanger. If the process requires 3 [kg/hr] of acetone vapor, find the heat required to generate the vapor, as well as the flow rate of saturated steam required to supply the heat. Assume that the inlet steam is superheated at P = 150 kPa and T=120 [C] and the outlet is a liquid/vapor mixture at P = 100 kPa with 20% of the mass in the liquid phase. Include the following information in your solution A. Reference temperature for the vaporization process B. Enthalpy path for the enthalpy of each acetone stream relative to the reference temperature. C. Heat required to drive the vaporization process in units of kilowatts. D. Mass flow rate of steam
