Refining Capability and Experience

Worleyprovides a comprehensive range of refinery services backed by over 60years of global experience in grass roots, revamp and expansionprojects. To meet client requirements in today’s competitive world, wesupply innovative, cost-effective, and safe solutions.
We havecompleted 29 grass roots refineries including supporting utilitysystems, product terminals and offsite facilities ranging in capacityfrom 5,600 bpd to 400,000 bpd that produce a variety of productsincluding LPG, gasoline, kerosene/jet fuel, gas oil and heavy fuel oil,petrochemical naphtha, distillates, and lowsulfur fuel oil.
Worleyhas also provided engineering, procurement, and construction servicessince 1965 for more than 60 major refinery revamp, modernization, andexpansion projects in Australia, Korea, Bahrain, the United ArabEmirates, Kuwait, Lebanon, Saudi Arabia, Turkey, Germany, the UnitedKingdom, Venezuela, Canada, Mexico, and the United States.
Worleyis a leader in designing solutions to meet clean fuels regulations thatnow face refiners around the world, including government mandates onsulfur, aromatic, and oxygen content of fuels. We have extensiveexperience with the two major types of clean fuels projects:reformulated gasoline and Ultra Low Sulfur Diesel (ULSD).
Worleyrecently completed three diesel hydrotreater projects to reduce dieselsulfur, including two grass roots units and conversion of
anexisting hydrocracker to a diesel hydrotreater. Gasoline reformulationexperience includes gasoline fractionation, benzene saturation forreduction of benzene in gasoline to meet CARB II and EPA Tier IIrequirements, catalytic reforming, cat cracker feed hydrotreating,selective hydrogenation units, isomerization units, butamer units,alkylation units, and FCC revamps.
From feasibility studies tofacility operations, we have the resources and capabilities to completeany refinery project using a variety of contracting approaches.
Manyof our clients benefit from alliance/partnering contracts with us thatuse integrated engineering teams that can deliver cost and schedulesavings compared to conventional project execution methods. Underseveral “umbrella” contracts with major petroleum refiners, we provideclients with a single source for the resources and technology needed tomeet the unique requirements of the operating refinery.
Of vitalimportance to this effort is the dedication and ability ofWorley employees who work hand-in-hand with refinery personnelto meet the project goals of the refinery's management.

Previous performance
Voyageur Upgrade Hydrotreater Project

TheVoyageur Upgrader Project (VUP) encompassed the delivery, upgrading,marketing and infrastructure growth required to increase the totalSuncor Oil Sands production capability from 357 KBPCD in 2008 (postMillennium Coker Unit start-up) to 550 KBPCD by 2010 to 2012.Worley was responsible for the EDS and detail phase engineeringand procurement for the Voyageur upgrader UOP hydrotreating units, HTUs(coker gasoil, coker diesel and coker naphtha). The HTUs process allthe Voyageur Upgrader delayed coker side streams to reduce productsulphur, nitrogen, and aromatics content. HTU catalyst beds andoperations were optimized to obtain 30 months between bed replacements.

Riode Janeiro’s Petrochemical Complex will be one of the largestindustrial undertakings in the history of Petrobras and Brazil with atotal investment of US $8.5 billion. Due to come on-stream in 2013,COMPERJ will have the processing capacity for 150,000 bpd of Brazilianheavy oil and will include first, second, and third generation units.This project will require approximately 4,000 major pieces of equipmentand in excess of 2,000 P&IDs, and the site plan will take nearly 25km2 to accommodate infrastructure and process units. Executed fromthree of Worley’ global hubs, key challenges successfullyovercome included cultural, language, and regulatory barriers, thelarge size of the project, and the coordination with the many licensorsand FEED contractors involved.
SAMREF Clean Fuels Project

Worleyis providing SAMREF with assistance in modifying its Yanbu refinery tocomply with 2013 mandatory specifications for gasoline with 10 ppmsulphur, 1% benzene, and diesel with 50 ppm. Diesel with 10 ppm ofsulphur will be mandatory by 2016. Phase 1 will start-up 1Q2013 after arefinery turnaround and will install a grassroots desulphurizationtrain to treat 60,000 BPD of FCCU gasoline. The project will also havean extensive brownfield component to revamp the 98,000 BPD distillatehydrotreater, and the refinery utilities infrastructure. Phase 2 willstart-up by the end of 2015. The scope may include a new high pressuredistillate hydrotreater hydrogen manufacturing, sulphur recovery, andoff-sites and utilities infrastructure.

Point Forward Refinery Expansion

Worleyperformed FEED, detailed design, and procurement services for thisgreenfield/brownfield refinery expansion that added a new grassroots3,500 tons/day CCR Platformer, a new naphtha splitter, expansion ofCDU1 capacity to 13,000 t/d, facilities to increase naphtha HDScapacity by 1,400 tons/day to 5,400 tons/day, and conversion of anexisting semi-Regen platformer to a 1,000 tons/dayPar-Isom/de-Isohexaniser isomerization unit (Par-Isom/DIH). The projectwas executed by teams located in California, New Zealand, and Beijing.A key challenge was integrating new units into the existing processcontrol system while upgrading the brownfield process units.
