Kettle reboiler design

[sniperel]

Hy! I need to calculate a kettle reboiler using HTFS 2006 but when I enter the process data some errors occur: due to small pressure drop, the temperature for cold fluid (shell side) decrease instead of increase. Pls help!

hi
composition/type- of shell fluid-NGL,LPG,...????
Possible J-T effect,

Phase behavoir of hot fluid ,vapor/liquid ratio.P,T flowrate...

check on hysys rigorous heat exchanger,solve it and
upload stream data from hysys on htfs

Hy! the fluid is propane in both shell and tube but at different temperatures and pressure.(I need to subcool liquid propane in tubes by vaporizing liquid propane in the shell). The pressure drop in shell decrease the outlet temperature causing an error to HTFS.
Please advice me!
Thanks!

hi
as i told you have Joule-Thomson effect -propane is an component of NGL,LPG,GPL l

I have checked an excample with htri and htfs. the results were egual, but the shell diameter was different. I have a problem with the liquid particle in the gas-stream. can anybody help me? What is the rightly gas velocity and shell diameter.

thanks
