Steel chemical cleaning - When to stop?
Steel chemical cleaning - When to stop?
(OP)
We usually performe chemical cleanings to some equipments, like pumpes, piping, vessels, in a closed circuit usually with citric or phosphoric acid. I was told that the best way to know when to stop the cleaning (if visual inspection is not possible) was to do some total iron analysis. Is this true? If so, how does the iron chart looks like?

You would want the lube oil and seal oil systems for your 35000 hp gas turbine compressor package to be cleaner than your crude oil separator.

Determination of the end point is part of the original cleaning plan. This needs to be desinged into your process.
