I have only seen this happen once, and it was due to oil content.
It is indeed caused by oil. . . . This has also happened to us
The phenols carried by the acidic water from upstream are generally colorless when observed through the glass panels of the liquid ammonia tank; however, upon contact with air during sampling, they oxidize to quinones and turn red.
It is caused by the oxidation of phenolic substances present in acidic water
The reddening of liquid ammonia is mainly caused by phenolic substances, which is related to the properties of the crude oil. Some devices have it, while others don’t.
How was it resolved later on?
