Our Solution

A worst case scenario of vessel and residues was selected for detailed analysis. A finite element model was used to predict the temperature rise in the residues, if the water was removed from the vessel. This included consideration of conductive and convective heat transfer within the vessel walls and the residue bed.

It was possible to show that the temperature rise in the residues as a result of draining the water was significantly below the level of concern and a new safety case could be developed for draining the vessels.
