Conclusion

What Future for CCR Reformers?

Refining• Increasing H2 demand for HDT units• High and continuous H2 production requirement• Replace Octane loss due to FCC gasoline HDS

Octanizing process

• Steady increase in demand for aromaticsPetrochemicals

• High severity requires CCR

Reactor Design

HC FeedSimple and cost-effective concept:

Catalyst in • design optimized for process conditionsi l i t l l t• simple internals, low stress

• flexible for increased capacity

High capacity:• unconstrained reactor design no

Catalyst out

• unconstrained reactor design, no compromise on design criteria

• thermal expansion is easilyHC Effluent

Side by Side reactors arrangement:

thermal expansion is easily managed


Side by Side reactors arrangement:the higher the capacity, the greater the advantage
