Abstract:

This article presents the design of a reactor unit for a catalytic cracking unit using oil from the Novopetrovskoye field as an example. Material and heat balance calculations were performed, and key process parameters were determined, such as cracking temperature (763 K), The catalyst-to-feedstock circulation ratio (7:1) and feedstock conversion rate (75 vol.%) were calculated. The reactor´s main geometric parameters were determined based on the calculations: diameter (7.6 m), fluidized bed height (6.47 m), and overall apparatus height (34.42 m). The stripping zone (desorber) dimensions were calculated, and a distribution device for the steam-catalyst flow was selected. Auxiliary equipment was also calculated and selected, including feedstock inlet units, gas distribution devices, and a pump. The study demonstrates an integrated approach to the design of a key element of a catalytic cracking unit, providing the necessary conditions for efficient process operation and product separation.

Keywords: cracking temperature, catalyst, reactor, unit.
