Hi all,
So I am designing a vacuum distillation column's total condenser. I carried out a bubble point calculation for a total condenser to determine the top product temp coming out of the condenser. I was wondering how should one go about finding the inlet temperature for the vapor entering the total condenser (required to find the heat load and proceed with the design further)? My thought process was to carry out a dew point calc as you would for a partial condenser and use the temp obtained from that as your inlet temp for the total condenser and work out the temperature difference that way to determine heat load. Apologies if this is a silly question I did not have the best semester during my unit op classes because of COVID.
Its my first time posting on this forum but I believe you all often require additional details surrounding the problem so here are the details surrounding the column:
- Condenser temp ~90°C
- Reboiler temp ~155°C
- Components and corresponding non-key distributed revised material balance is attached as a table to this post (Click Me).
- Note the temps are not exactly accurate because i used a similar component to substitute the TPG's Tc, Pc and Acentric factor data whilst doing the shortcut design (FUGK method). HYSYS V9's rigorous and shortcut column have shown 100°C and 160°C as the condenser and reboiler temps respectively (using NRTL). Again, apologies if this is a silly question. First time designing a condenser and reboiler for a distillation column (and first time designing a distillation column in general).
Regards,
Jay
