4. INTRODUCTION
LIQUID- LIQUID EXTRACTION IS A
MASS TRANSFER OPERATION LIKE
DISTILLATION
LEACHING
DEHUMIDIFICATION
GAS ABSORPTION
CRYSTALLIZATION etc.

5. DEFINITION
LIQUID-LIQUID EXTRACTION IS USED TO
SEPARATE TWO MISCIBLE LIQUIDS.
BY THE USE OF A SOLVENT WHICH
PREFERENTIALLY DISSOLVE ONE OF
THEM OR MOSTLY THE REQUIRED
COMPONENT.
IN THIS THE DRIVING FORCE IS THE
DIFFERENCE IN SOLUBILITY.

6. STEPS OF OPERATION
THERE ARE THREE STEPS FOR
THIS OPERATION:
1. CONTACT OF SOLVENT WITH
RAFFINATE.
2.SEPARATION OF TWO PHASES.
3.RECOVERY OF SOLVENT.

7. EQUIPMENT USED
PACKED TOWER
PLATE TOWER
SPRAY TOWE
MIXER-SETTLER UNIT

8. IMPORTANT TERMINOLOGIES
RAFFINATE
SOLUTE
SOLVENT
DILUENT
EXTRACT

9. RAFFINATE
THIS IS A MIXTURE
OF COMPONETS
WHICH IS TO BE
TREATED.
e.g
THE MIXTURE OF
(A+B),SHOWN IN FIG

MIXTUER OF
(A+B)

10. SOLUTE
THE COMPONENT
WHICH WE WANT TO
EXTRACT FROM
RAFFINTE
e.g
A IS THE SOLUTE
WHICH WE WANT TO
EXTRACT FROM
RAFFINATE

MIXTUER OF
(A+B)
A=SOLUTE

11. SOLVENT
THIS IS A LIQUID
WHICH WILL
DISSOLVE THE
ONE COMPONENT
(SOLUTE) FROM
RAFFINATE

12. DILUENT:
THIS IS COMPONENT
WHICH LEFT BEHIND
THE RAFFINATE
AFTER EXTRACTION
EXTRACT:
THIS IS A MIXTURE
OF SOLVENT &
SOLUTE
EXTRACT
(A+C)
DILUENT (B)
