A vapor mixture contains benzene (C6H6) and 10.0 mole% toluene (C7H8) at 110°C and 1.00 atm. A continuous stream of this vapor mixture enters a separator at 15.0 mol/hr. The streams exiting the separator are at a dew point (90°C and 1.25 atm). The liquid and vapor leaving the separator can be considered in equilibrium. The vapor leaving the separator is then heated isobarically to 130°C.(a) Draw a process flow diagram, number the streams, and label the phase of each stream (solid, liquid, gas).(b) Calculate the flow rate (mol/hr) and mole fractions of the liquid that exits the separator.(c) Calculate the volumetric flow rate (m3/hr) at standard temperature and pressure (STP) conditions of the vapor stream that exits the heater.(d) An alternative solution could use the dew point pressure form of Raoult's law. Derive the expression for the vapor mole fraction of exiting benzene, and check the answer with the previous solution.(e) The separator breaks down making the process isobaric. Will the benzene composition of the liquid leaving the separtor increase, decrease, or stay the same?

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
