Question

Distillation needs energy or gives out energy?please dont spam​

Answer 1

Answer:

Distillation processes are major industrial energy consumers, typically requiring significant amounts of heat in the reboiler and rejecting similar amounts of heat from the condenser, but at a lower temperature, limiting the potential for heat recovery.

Hope it helps you.. :)

Answer 2

Answer:

Distillation rules the separation landscape not because of any efficiency advantage but rather because of several other factors that favor it. For instance, distillation:

• scales well, generally to the 0.6 power;

• when performed by itself, doesn’t introduce an extra mass agent (solvent, sorbent, etc.) that needs subsequent recovery, as in the case of absorption or liquid extraction;

• allows heat integration within individual units and across facilities, which can foster effective heat utilization in many separations operations; and

• provides an inter-relationship between pressure and temperature.
