The effect of evaporation on the output of literature dynamic models for hydrotreating trickle-bed reactors was examined. The model system, presented by Mederos & Ancheyta (2007), was applied to a given oil treating case. In order to account for evaporation, Pro/II flash calculations were implemented over the length of the reactor in cocurrent operation. It was found that, given the model and the chosen reaction network, the heat of reaction would result in a large fraction of the liquid feed evaporating in the reactor. It was also found that the reaction rate of the feed influenced the effect of the evaporation. A higher reaction rate was found to widen the range of outputs attainable between high and low mass transfer rates.
