The disproportionation of toluene to benzene and xylenes is carried out in a catalytic reactor at 500 psia and 950?F. The reactor effluent is cooled in a series of heat exchangers for heat recovery until a temperature of 235?F is reached at a pressure of 490 psia. The effluent is then further cooled and partially condensed by the transfer of heat to cooling water in a final exchanger. The resulting two-phase equilibrium mixlure at 100?F and 485 psia is then separated in a flash drum. For the reactor effluent composition given below, use a computer-aided, steady-state simulation program with the S-R-K and P-R equations of state to compute the component flow rates in lbmol/h in both the resulting vapor and liquid streams, the component K-values for the equilibrium mixture, and the rate of heat transfer to the cooling water. Compare theresults.
