I have come across a mention that indicates the Romans had it but not very
efficient and did not catch on. It all depends on the equipment.

Reportedly the pot still was perfected in Islam and there came to be used in
alchemy for extracting essences from every thing as in perfumes. The next
improvement would be the coil condenser.

Clearly freeze separation would have been known in any climate cold enough to
have freezing temperatures.
