How can I calculate the condenser and reboiler duties for a distillation column given the following data without using any simulation or software i.e by hand calculations.
Feed 1 (To Distillation Column) Stream 2 (Distillate) Stream 3 (Residue)
Temperature 35 71.5174 172 C
Pressure (absolute) 2280 250 250 mmHg
Mass Flow 10000.0008 999.7895 9000.2113 kg/h
Molar Flow 172.9571 55.4976 117.4595 kmol/h
Mixture Density 1651.6539 0.2091 370.6435 kg/m3
Mixture Molar Weight 57.8178 18.015 76.624 kg/kmol
Flow Energy (Stream) -1.8213*10^7 -3.7406*10^6 -1.364*10^7 kcal/h
Mass Flow (kg/hr)
Water 1000.0001 999.7895 0.2116 kg/h
Ethylene glycol 5500.0004 0 5500.0028 kg/h
Diethylene glycol 2000.0002 0 2000.0025 kg/h
Triethylene glycol 1500.0001 0 1499.9945 kg/h
Please suggest any method or procedure to carry out the calculations.
A small example would be helpful too.
Thanks
