Heat Exchanger Problem
Heat Exchanger Problem
(OP)
We are using heat exchanger to heat our borate/ethylene glycol solution to 180 F and cooling it down at 125 F. After it reached the 180 F we heat it further for an hour. We noticed that after 9 batches, the solution becomes grayish(comtamination most probably from the boiler and cooling sytem). We asked the heat exchanger specialist to come down to check if there is a leak but he can't find any. Can anybody help? I will appreciate any comment/help.
Thank you.
Thank you.

This way you can check your whole process step by step where a possible contamination could occur.
The other question could be: How was the HX checked for leaks (P and T)
