why is there is a need to have a continual flow of water in the condeser?

Answer 1

Water is constantly circulated in the water jacket to help cool hot vapors, condensing them into liquid...

Answer 2

There isn't, in fact it's sometimes possible to distill a material with a low boiling point in air.

The problem is that with normal substances, like water, if you don't keep the water flowing the condenser, and any water that might be in it, rapidly heats up until it's not cold enough to condense the material and it escapes in the form of a vapour (steam in the case of water).

Answer 3

When a vapor condenses into a liquid, the latent heat of vaporisation is given up by the vapor and the heat needs to be removed so that the system remains at a lower temperature. If not, the condenser's efficiency goes down.

Answer 4

Continuous and sufficient flow of cool water = continuous removal of Latent Heat of condensation and Sensible Heat of cooling from the produced vapour.
Loss of cooling will mean loss of product as vapour to the atmosphere.

(The maintenance of the correct amount of heat removal is a fundamental MUST in petroleum distillation operations).

Answer 5

For cooling...
