ENERGY BALANCE AROUND PRESSURE VESSEL

Energy Input:

Energy input with makeup water            = m C_p (25-25)            = 0

Energy input with fresh EO                    = 0

Energy with recycle stream                    = m C_p ΔT                               =5.04*10⁷ KJ/hr

Energy output:

Specific heat of stream leaving the pressure vessel

C_p                                = 0.831*4.1868 + 0.169*0.522*4.1868

                                                            = 3.848kJ/Kg.K

W_f                                = 129324 Kg/hr

Energy output                           = W_f C_p ΔT

                                                            = 129324*3.848*101

                                                            = 5*10⁷ KJ/hr
