Abstract
An apparatus comprising a feed distributor comprising a side cluster of orifices instead of or in combination with an end cluster of orifices for distributing hydrocarbon feed into a catalyst stream. A side cluster of orifices in conjunction with an end cluster of orifices on a feed distributor can distribute hydrocarbon feed into a riser over a greater cross-sectional extent enabling emission of smaller droplet sizes which provide better conversion with less coke production.
Claims20
A system comprising:
- a reactor and an apparatus for distributing a hydrocarbon feed to a stream of catalyst in the reactor comprising, wherein, the apparatus comprises:
- a feed distributor comprising a barrel;
- a first cluster of orifices at a first position on said feed distributor;
- a second cluster of orifices at a second position spaced apart from the first position on said feed distributor;
- and
- a first conduit extending from an internal oil pipe, said first conduit having a tip providing said first cluster of orifices and a second conduit extending from said internal oil pipe, said second conduit have a tip providing said second cluster of orifices,
- wherein said reactor comprises a riser having a wall and said feed distributor protrudes through said wall of said riser.
An apparatus for distributing hydrocarbon feed to a stream of catalyst in a riser reactor comprising:
- the riser reactor;
- a catalyst inlet in said riser reactor;
- a feed distributor comprising a barrel having an inner end for distributing feed to the riser reactor;
- a first cluster of orifices located on a first side tip at a first position on said feed distributor spaced apart from the inner end;
- and
- a second cluster of orifices located on a second side tip at a second position spaced apart from said inner end and said first position on said feed distributor.
An apparatus for distributing feed to a reactor riser comprising:
- a first level of feed distributors including a first feed distributor comprising a first number of clusters of orifices for distributing feed to the riser;
- and
- a second level of feed distributors including a second feed distributor comprising a second number of clusters of orifices for distributing feed to the riser, the second number being greater than the first number and the second level being higher than the first level in the riser.
