Answer 1

1. PHASE CREATION
2. PHASE ADDITION
3. BARRIER
4. SOLID AGENT
5. FORCE FIELD OR GRADIENT

Question 2

Answer 2

REFER TABLE

Question 3

WHAT IS THE MECHANISM BEHIND PHASE CREATION ?

Answer 3

1. CREATES A SECOND PHASE WHICH IS IMMISCIBLE WITH THE FEED PHASE
2. USING ENERGY TRANSFER OR PRESSURE REDUCTION
3. EXAMPLES ARE DISTILLATION (DIFFERENCES IN VOLATILITY) AND CRYSTALLIZATION (DIFFERENCES IN MELTING POINT)
4. USES EITHER ESA OR MSA

Question 4

WHAT IS THE PRINCIPLE BEHIND ESA?

Answer 4

1. INVOLVES HEAT TRANSFER OR SHAFT WORK TRANSFER TO OR FROM THE MIXTURE
2. SHAFT WORK IS THE CREATION OF VAPOR FROM A LIQUID PHASE BY REDUCING THE PRESSURE
