FLEXICRACKING Unit

ExxonMobil has experience in designing over seventy fluidcatalytic cracking units worldwide - ranging in capacity from 3kB/D to 140 kB/D.

Expect these advantages:

• High-efficiency riser termination for improved productselectivity

• Efficient feed injection system to minimize gas and cokeyields

• Designs to improve overall structural cost and access• Efficient stripper design for improved solid / vapor contacting and reduced

hydrocarbon carry-under• Mechanical features for high reliability and reduced construction cost (such as

cold wall and minimum expansion joints designs)• Process control features for improved yields at lower operating costs• Feed flexibility that can include resid processing

Operators Understand Performance Drivers

ExxonMobil provides its licensees with FCC fluidization expertise, troubleshooting,operations support and training. Using advanced state-of-the-art process modelingcapabilities, ExxonMobil can provide yield and product quality predictions, feedstockevaluations and catalyst selection support.

Orthoflow Resid FCC Converter

Reactor-side Technologies are aimed at improving productselectivity through the reduction of coke and gas yields.These technologies offer increased operability and reliablity

Regenerator-sideTechnologies

RiserTermination / Short ContactTime (SCT)Technologyprovides optimal catalyst hydrocarboncontacting andseparation.

Feed InjectorTechnologyincreases the yield of high-valueproducts through superior feed atomization anddroplet distribution,plus improved risertemperature profilesand coke and gasselectivity benefits.

Reactor-side Technologies

Feed Injection Zone Technologyevenly distributes catalyst acrossthe riser prior to contacting feed, thus controlling backmixing

feed

Stripper Technologyreduces hydrocarboncarry-under at lower steam consumptionand combustion airrequirements thanprovided through conventional strippingtechnologies - all at areduced cost.

Cyclone Technologiesprovides excellentcatalyst / vaporseparation with minimalerosion.

Regenerator-side Technologies offerreliable, reduced operating costregeneration options to minimize catalystdeactivation, limit NOx emissions, andprovide flexibility for feedstock and catalystchanges. The integrated mechanical and process design minimizes thermal stressesand polythionic stress corrosion cracking.

Wet Gas Scrubbing (WGS)Technology simultaneously controlsFCC unit flue gas emission of SOx and particulates. The WGS systemis commercially proven, reliable, androbust.

Third Stage Separator(TSS) Technologyachieves higher removalof small particlescompared to other commercial third stageseparator systems andcan often meet particulateemission standardswithout an electrostaticprecipitator or scrubber.

Catalyst CoolerTechnologyprovides additionalregeneratorcooling for higherconcarbon / residfeedsocks.

Distributor Technologyimproves regenerator operability, resultingin low carbon on regenerated catalyst andafterburn control.
