1. Internal leakage in the heat exchanger 2. Tower flooding

It could be an internal leak in the heat exchanger, or it might be the result of severe corrosion of the equipment and pipelines.

If the boiling range is fine, it’s likely due to severe corrosion of the equipment and pipelines, a short residence time, and the presence of substances resulting from that corrosion. When there is an internal leak in the heat exchanger, the boiling range will be unsatisfactory.

The original poster has explained it very clearly: it’s either internal leakage in the heat exchange system or tower flooding. If it’s caused by corrosion, then it’s due to iron sulfide
