What is it?
Condensation-
Is a change of form from a gaseous state to a
liquid state
SLIDE 4
First Method
Raise the pressure and keep temperature
constant
SLIDE 5
VLE Diagram
SLIDE 6
Compressors
SLIDE 7
There is a problem
TOO MUCH HEAT!!!
SLIDE 8
Heat Exchangers
SLIDE 9
Compressors + Heat Exchangers
Compressors raises pressure and
temperature
Heat Exchangers remove heat Readily available Takes up a large portion of space
SLIDE 10
The Second Method
Lowering the temperature and keep
pressure constant

Refrigeration
Similar to domestic refrigerators
Hot air Compressor Refrigerant
Gas Repeat
Relatively expensive

Turbine Expanders
Mechanical Energy Kinetic Energy
Potential Energy Kinetic Energy Mechanical Energy
Wow!
Work can be 100% recoverable
Less cost

Summary
↑ Pressure, Temperature constant
Compressors + Heat Exchangers
↓ Temperature, Pressure constant
Refrigeration and Turbine Expanders

Final Thoughts
Turbine Expanders Ethane Refrigeration Cost down, efficient
liquid recovery
Compressors + Heat Exchangers In
every chemical plant. Bulky
