Hi! I would like to ask especially those people who have an expertise in operating Delayed Coker Unit. We are currently experiencing high fluctuations in the product flows especially during their backwarming activity. The problem is that the downstream units experienced high feed fluctuations which will affect the operation of their unit and the feed quality. In our plant, most of the downstream units of Delayed Coker Units were hydrotreaters. But because of the feed fluctuations, we are forced to use recirculation lines in the hydrotreaters but this would result also to variations in feed quality, not constant hydrogen flow and unstable operation. With this, what is the recommended control in the Delayed Coker Unit in order to avoid such problems and have a constant product flows?
Thank you so much!
