Hi Guys,
Firstly, I would just like to say this is my first post, so apologies if I've made any mistakes!
I've been doing a project on the production of Ethylene Oxide (oxygen based) and now have to delve further into a specific component.
Let me give a little information on the process
- Three main sections; Reactor, CO2 Removal and the Purification section
- Assumptions have been made based on literature and research that affect the mass balance, I would type them here but there are quite a few. (If you would like them to assist with the answers, please let me know and I will provide)
The component I have chosen to base my project on is the Light Ends Column which can be found in the Purification section. My Understanding is that here, the light ends (i.e. the impurities) will leave as through the vent in the column and a solution of EO and Water will enter the final distillation column. There will be trace amount of impurities entering the DC and I have accounted for that in the mass balance.
My Questions:
- If there is a vent present in the column, does this mean the pressure inside the column will be atmospheric?
- Does the Mass Balance look okay? (notice it's in kmol/hr)
- How would I go about working out the temperature?
- What would you recommend doing in terms of starting the design?
Thanks so much for reading and any answers or suggestions you give are much appreciated.
