dephlegmator design
« on: March 08, 2018, 02:09:58 AM »

Hi
I woudl like to know there in which book I can find dephlegmator/partial condenser design procedure. My final year design project is deethanizer distillation column. I used partial condenser but I have difficulties to find information. ???

Refrigeration cycle
« Reply #1 on: March 12, 2018, 09:11:20 PM »

I am trying to design refrigeration cycle with propylene refrigerant. I am planning to use heat exchanger for subcooling of liquid and superheating of vapor. I choose centrifugal compressor and water-cooled type of condenser. Evaporating temperature is -38C. It is needed to cool down light hydrocarbons from -26C to -35C. Could you please check the datas I wrote?
In Pressure-Enthaply
A - after condenser (0.62 MPa , 5C)
A* - after subcooling HE (0.62MPa, -10C)
B - after throttling valve (0.16MPa, -38C)
C - after evaporator (0.16 MPa, -38C)
C* - after superheating HE (0.16MPa, -14C)
D - after compressor (0.62 MPa, 50C)
E - condenser (0.62 MPa, 5C)

Nice Datas :) From what I can tell with the chart I think you have the right idea.

For Partial condenser design and fundamentals, here is a paper you may find some good information as well as other sources to explore the matter further: https://pubs.acs.org/doi/abs/10.1021/ie300818b

good luck with your design project!
