Hello everybody,

 

Im studying chemical engineering course and this year is my final year. im designing shell and tube partial condenser in order to knock out the non-condensable gases out of the system.

 

the inlet of my equipment design are 10 component in the vapour phase which are:

 

nitrogen - hydrogen - carbon monoxide - carbon dioxide (non- condensable gases)

 

methanol - acetic acid - propanoic acid - methyl acetate - water - methyl iodide..

 

i have started with the condnsation curve (integral one) but then after that im stuck dont know what to do after ..

 

even in HYSYS simulation software, condensers can not be designed !!!

 

 

can anyone please help me with my design issue ?

 

 

many thanks,

Abo_loloah

Try higher pressure or lower temperature to obtain condensate.

Just about any Process Heat Transfer book has information on designing a partial condenser in a shell-and-tube heat exchanger..

i have tried process heat transfer by Hewitt , Coluson and Richardson vol 6 and many other book ..

 

i could not find the procedure for designing this equipment..

 

many thanks,

OK.  Some people need to led by the hand:

 

Go to your local technical or engineering library borrow the book:

 

"Process Heat Transfer"

by Donal Q. Kern

McGraw-Hill Publishers

1950

 

(if you can't find the book in the library, then go to Amazon.com and buy the book as used issue.)

 

Go Chapter 13 titled: "Condensation of Mixed Vapors".  There you will find a complete explanation of the theory as well as worked out examples.  If you can read English, and you have already had heat transfer courses in university, you should have no trouble resolving this problem.

 

I hope this helps you out.
