Operation condition analysis of distillation
Thread Content
A batch distillation unit for methyl acetal is now to be installed; the feed material consists of 85% methyl acetal, with the remaining 15% being a mixture of water, toluene, and solvent oil. Now, the output from the tower top is required to be 95% methyl acetal. During the distillation process, the temperature at the top of the tower is the boiling point of methyl acetal. What about the temperature at the bottom of the tower? Why does Aspen simulation show it to be in the high 60s degrees?
Waiting for the great Aspen to provide an answer
For distillation column packing and internal components, contact me.
If you think it’s wrong, then what should be correct? If it’s an error in the simulation process, if you don’t explain the steps you took, how can those familiar with the software know where the mistake lies? Could this way of communicating solve the problem?
You should take out the simulations you’ve done and take a look
It would be best to upload the simulated BKP file for a look
The requirements for this separation aren’t high; what’s the need for simulation? 10 plates will definitely meet the requirements.
The bottom temperature is the bubble point of the reactor liquid, which is related to composition and pressure. Write down the composition of your kettle liquid.
