Fluor's scope of facilities for the project were the CO2 Capture Facilities and related interconnecting facilities which capture the carbon dioxide from the process gas streams of the Hydrogen Manufacturing Units (HMUs) where hydrogen is produced for the conversion of bitumen to synthetic crude oil. The carbon dioxide is removed from the HMU “syngas” by contacting the mixed gas stream of methane, carbon dioxide, carbon monoxide, and hydrogen with activated amine. The carbon dioxide is separated from the amine in a common amine regeneration process that produces 95% pure carbon dioxide at a pressure slightly above atmospheric pressure. The purified carbon dioxide stream is then compressed to a supercritical state and dehydrated by a multi-stage compressor and then transported via pipeline for off-site disposition.
The CO2 Capture Facilities consist of the following:
- Amine absorption units located in each of the two existing HMUs of the existing Upgrader as well as the Expansion HMUA common amine regeneration unit
- A CO2 compression unit
- A dehydration unit
- Utilities and Offsites tie-ins
- Modifications on the two existing HMUs and the Expansion 1 HMU.
Fluor's scope of services on Quest were for the provision of engineering, procurement, construction, and construction management of the CO2 Capture Facilities, including the interconnections and scope within the existing AOSP Base Plant Upgrader and Expansion facilities.
Fluor used its patented and innovative 3rd Gen Modular Execution approach for the 1.2 million tonne-per-year carbon capture facility at the Scotford Upgrader. Captured carbon dioxide is sent about 80 kilometers from the facility via underground pipeline to an underground storage site.
There were 69 separate interlocking modules assembled at the jobsite. The EPC and construction management services were for the pre-FEED, FEED and EPC phases of the project. Fluor was responsible for project management, quality assurance and control plans, engineering, procurement, contracting, project controls, construction, construction management services and information management services required to achieve the mechanical completion of the CO2 Capture Facilities and related interconnecting facilities to meet the project requirements of safety, budget, quality and schedule.
