Problems in determining distillation pressure using the simplified method
Thread Content
In ASPEN, the distillation of methanol and water is simulated using the simplified method; to carry out this simulation it is necessary to enter the pressures of the condenser and the reboiler. However, the problem only provides the operating pressure of the column. Could experts please advise on how to determine the pressures of the condenser and the reboiler based on the operating pressure of the column? See the figure for the specific question.
The operating pressure is the condenser pressure, while the reboiler pressure can be roughly set at operating pressure + 0.1~0.5 bar.
