Hello Every one
Recently we have commissioned non-phenolic sour water stripping unit in our refinery. We have very limited information in operating manual provided by designer.
A condensate stream is provided at overhead line of stripper for flushing of salts and other fouling materials. But no information is provided about when do we use this condensate stream and what will be schedule.
I am concern about H2S concentration in overhead line is very high so it can be use in normal operation or can be used only during shutdown of unit (corrosion concern). kindly answer the above quarries from your experience is needed.
Regards
