ÿ P/T conditions are adjusted for the Column ÿ
The distillation column operates with a partial condenser and reboiler ÿ The
current operation states that: ÿ N =
20 stages, being fed at 10th stage. Reflux ratio is 2.5 approx., with 2.15 – 21.50 Gas-Distillate
Ratio ÿ Dodecane is required at 150 kPa in the following Plant but Iso-Pentane is ready to ship to client.
ÿ A stream of three hydrocarbons are to be treated as follows: ÿ Methane,
Iso-Pentane and Dodecane must be separated. ÿ Methane is
only useful as a fuel, must be separated in a flash drum and sent to stack ÿ Main separation
is achieved in a Flash Drum ÿ P/T is adjusted to:
15°C, P = 456.6 kPa. Operation is Adiabatic
ÿ Dodecane and isopentane are valuable, so they must be further separated

ÿ The Combustion chamber has the following conditions: ÿ Approx.
100% conversion ÿ Q =
adiabatic operation ÿ Air is
used for oxidant
ÿ T = 350°c, P = 405 kPa inlet conditions
ÿ dP = 125 kPa approx.
ÿ Turbine is used to decrease Pressure of the stack gas.
