Low Sulphur Gasoline Project
Front-end engineering definition (executed in Toronto) and EPCM phases (executed in Montreal) for a grassroots 29,000 bpsd CCG Hydrotreater using IFP's Prime G+ process at Petro-Canada's Montreal East refinery. The project included a debottleneck of the Hydrogen Plant from 45 to 54 mmscfd and the upgrade of various utilities, offsites and facilities. Client: Petro-Canada Products Ltd.

Syncrude Upgrader Expansion Project (UE-1)
SNC-Lavalin, as part of the Alliance 21 Joint Venture, was awarded a contract to develop Design Basis Specifications (DBS), the major component in an overall Design Basis Memorandum (DBM), and to provide detailed engineering, procurement and construction support services to increase bitumen production from 110 million b/y to 145 million b/y (33% increase).An integrated project team was assembled including the engineering contractors, construction contractor and the client staff to complete process design, basic and detailed design and supply all of the equipment and materials for direct hire construction. Client: Syncrude Canada Ltd.

Petrotrin, Trinidad & Tobago: Ultra Low Sulphur Diesel (ULSD) Project

As Program Manager in an integrated project management team (PMT), SNC-Lavalin is responsible for the new ULSD facility that forms a key part of the Petroleum Company of Trinidad's (Petrotrin) clean fuels upgrade program. The ULSD Unit is designed to process 40,000 barrels per stream day of diesel feedstocks to produce a low sulphur (8 ppm) diesel consistent with the most stringent North American on-road fuel specifications. The heart of the ULSD facility is a high pressure, catalytic, hydrotreating process.As part of an integrated PMT with Petrotrin, SNC-Lavalin supports the project by defining, reviewing, monitoring, evaluating and controlling all aspects of the project's execution. SNC-Lavalin's scope of work includes management of engineering, procurement, construction, health & safety, quality and commissioning aspects of the project.SNC-Lavalin's scope also included helping to select an EPC contractor who then built the facility under the supervision of the PMT.

Valero Flue Gas Scrubber Project
The US$600M+ Flue Gas Scrubbing Project involved completion of front-end engineering, detailed engineering, procurement support, and construction management support. The scope included installation of new furnaces, which replaced existing units, new Selective Catalytic Reactors (SCR), a Waste Heat Boiler (WHB), a Belco pre-scrubber including sub-cooling, and a Cansolv SO2 absorber/stripper unit, reagent handling and regeneration facilities to reduce emissions. The new furnaces, which were designed for over three years of continuous operation without interruption, were integrated with the other flue gas scrubbing components for more profitable refinery operations.
