Definitions
- reaction zone 3 Hydrocracking or deeper hydrotreating takes place in reaction zone 3 depending on the type of catalyst used in that zone.
- the effluent 65 from reaction zones passes to reaction zone 10.
- Fresh feed 1 is introduced at an intermediate point between reactor beds 3 and 10. It is processed in the presence of the effluent 65 from the upper reaction zone 3.
- Effluent 65 assists in distribution of feed stream 1 through reaction zone 10.
- Effluent 65 also acts as a heat-sink for the exothermic reaction in reaction zone 10.
