At the elbow of the top reflux drum of the reforming pre-hydrogenation stripper (c-102). 2. Water injection point before air cooling at the top of the diesel hydrodesulfurization stripper (c-101). Fortunately, it was detected in time and no major accidents occurred, but the diesel hydrogenation process had to be stopped. If we keep these things in mind and pay attention to them during previous maintenance checks, by measuring the wall thickness of these key areas and assessing the degree of corrosion there, it might be possible to avoid shutting down operations.
