Abstract
A fluid catalytic cracking (FCC) unit for the production of hydrocarbon products includes a fluid injection system coupled to a reactor by a standpipe. The fluid injection system includes a plurality of nozzles for injecting oil feedstock into the standpipe to react with a catalyst flowing therethrough.
Claims18
A fluid injection system for a fluid catalytic cracking unit having a cracking standpipe into which oil, steam, and a catalyst are introduced at elevated pressure and temperature to crack the oil into constituent portions, the fluid injection system comprising:
- a manifold coupled to the cracking standpipe, the manifold having plurality of inner passages for distributing flows of oil and steam through the manifold, a plurality of inlets in fluid communication with the plurality of inner passages, and a plurality of outlets separated from the plurality of inlets and in fluid communication with the plurality of inner passages;
- a plurality of separate mixing chambers circumferentially disposed about the manifold, each mixing chamber configured to atomize oil supplied to the mixing chamber and mix the atomized oil with steam supplied to the mixing chamber;
- a plurality of multiflow control blocks circumferentially disposed about the manifold and coupled to the plurality of outlets, each multiflow control block configured for controlling the flows of oil and steam into a corresponding one of the plurality of mixing chambers;
- and
- a plurality of nozzles circumferentially disposed about the standpipe and extending through respective apertures into the standpipe, the plurality of nozzles in fluid communication with the plurality of mixing chambers for directing the oil and steam mixture into the standpipe in a controlled manner for reaction with the catalyst.
