Abstract

The final stage of revamping of the GK–3 cat cracker reactor block with introduction of new technology is described. The elements of implantation are: combined external riser reactor; high–efficiency feedstock and slurry nozzles; crude treatment cyclone; cracking product cooling unit; two–stage catalyst stripping; regenerated catalyst transport system. As a result, the yield of naphtha is increased by 4.6 wt. %, and steam consumption in the reactor block is reduced by 15%; the unit is converted to a two–year servicing schedule; the feedstock is high–end–point vacuum distillate; the reliability and safety of operation are increased.
