2. INTRODUCTION
 “Distillation is an unit operation which involves separation of a
vaporizable component from a multi-component system and
subsequent condensation of vapours.”
 Distillation is a process of separating the component
substances from a liquid mixture by selective evaporation and
condensation.”
 “Distillation is defined as the separation of the components of
a liquid mixture by a process involving vaporization and
subsequent condensation at another place.”

3. Membrane Assisted Distillation
Membrane-assisted distillation is the integration of
a membrane with a distillation process, which complement each
other to achieve a defined separation task.
Hybrid separation processes combine two or more unit operation,
which contribute to given separation task by means of different
physical phenomena.
Membrane-assisted distillation processes constitute one type of
hybrid separation process.
In a membrane separation, a feed mixture flows over a membrane,
which allows to molecules to pass through membrane and some
are rejected.

5. Advantages of membrane assisted distillation
 Membrane assisted distillation offers significant potential for
the separation of close boiling or azeotropic mixture.
 In contrast to distillation, membrane separation is not limited
by vapour liquid equilibrium(VLE) and thus overcome
azeotropes and distillation boundaries.
 High selectivity, low energy consumption and compact
modular design .
