this is a table that I have to show the temperatures of the inlet and outlet streams, is it feasible to have a distillate temperature in the negatives? If so, how can I make it feasible in the physical sense? (i.e. what coolant would I use, material etc)

I started off designing this as a simple distillation column but after doing some reading I have seen a number of columns being mentioned, I am wondering what column is best for this separation?
Is it a standard distillation column or something else?
(If you see any other mistakes, please can you point them out, thanks!)
Thanks for all your help.
