Hello,
I am trying to design a multi component distillation column for the separation of the following components:
FEED:
- Ethylene Oxide
- Water
- Carbon Dioxide
- Acetaldehyde
- Formaldehyde
- Ethylene
- Oxygen
- Methane
DISTILLATE:
- Methane
- Ethylene
- Oxygen
- Formaldehyde
- Acetaldehyde
- Carbon Dioxide
- Ethylene Oxide
BOTTOM:
- Ethylene Oxide
- Water
- Formaldehyde
- Acetaldehyde
The feed temperature is 40 C (I haven't made any calculations for this, I have a heat exchanger before the feed enters the column which will heat up/cool down the stream) and the cooling water I am going to use is 35 C.
I understand the pressure at the top will be lower than that at the bottom but I am struggling to calculate the exact pressure at the feed, top and bottom.
Question:
- What information do I need to calculate the pressure in all three cases
- How would I calculate the pressure
- Is the temperature I've got reasonable?
Thanks for all the answers in advance!
