Distillation
Coloumn
Distillation is a method of separating
chemical substances based on
differences in their volatilities.
Distillation usually forms part of a
larger chemical process. In the
distillation column, more volatile
components are in the distillate,
while less volatile components are in
the bottoms. Separation is
accomplished by boiling. Each tray
accomplishes a fraction of the
separation task by transferring the
more volatile species to the gas phase
and the less volatile species to the
liquid phase. Material and energy
balances can be performed on an
individual tray, the column, bottom
reboiler, or top condenser, or the
entire system.
