Hi All,
I was informed we are having high pressure drop across one of HXER for a WFI (Water-For-Injection) supply loop.
Please, I need technical advise on how I can trouble shoot the problem.

You should first ask if this is a problem. Next, compare it to what you expect. Then proceed if you can't send the problem back to the originator.

Talk to your operators and maintenance folks about it. They are a wealth of knowledge.

Biodun,
You will need to provide more information.
Specifically you will need to get the P&ID for the system or at least the PFD.
Also gather the inlet and outlet pressure for the heat exchanger.
If your plant has some sort of historian/DCS, this is a good source of
to determine when the problem first started.
When you provide this information we can be of more help on this forum.

Hi ,
You should compare the HX data sheet with the data gathered at site .Make sure the Pressure Gauges or Transmitters are reliable before collecting data .Is it an old issue or a new one ?
What about pluggage of the lines ? do you have filters before HX ? etc....
A sketch will help !
my 2 cents
