Establish the maximum allowable pressure drop across the catalyst bed structure in a hydrocracker

The reaction section of a hydrocracker unit has three reactors configured in two stages.

The reaction section of a hydrocracker unit has three reactors configured in two stages. Most of the cracking takes place in the third reactor (of interest), which uses a high-activity hydrocracking catalyst in its top four beds. As the feed and recycle gas mixture enters the top of the reactor, it flows evenly over the reactor cross-sections before flowing down to each of the catalyst beds. The catalyst is designed to remove organic metals from the feed and is graded to provide maximum surface area to collect pipe scale and other solid particles with minimal impact on reactor pressure drop, as shown in FIG. 1.
