| 英文摘要: | The Alberta Carbon Trunk Line (ACTL) plans to transport CO2 from a number of sources in Alberta’s Industrial Heartland, near Redwater, to declining oil fields in Central Alberta for the purpose of enhanced oil recovery (EOR). When operating at full capacity, the pipeline is designed to transport up to 14.6 Mtpa of CO2. The initial sources of CO2 for the ACTL are the (existing) Agrium fertiliser plant and the (new build) North West Redwater bitumen refinery, both close to Redwater, Alberta. The combined capture of CO2 from these sources is between 1.6-2.0 Mtpa.
The Agrium fertiliser operation at Redwater is the largest in Canada and one of the largest in North America. It produces close to 1.4 million tonnes of nitrogen based nutrients each year. The CO2 stream from the plant, a by-product of the fertiliser manufacture process, is presently vented to the atmosphere. A CO2 recovery facility, situated on the boundary of the Agrium plant, is being constructed by Enhance Energy. This facility will compress and dehydrate the (wet) CO2 emission stream so that it meets transportation specifications.
The mass of CO2 available for transport will vary dependent on the actual outputs from the Agrium plant. When fully operational, the CO2 recovery facility would provide between 800-1,600 tonnes of CO2 per day for transport (and reduce process CO2 emissions by 95 per cent). The purity of the CO2 stream prior to transport is >95 per cent.
Enhance Energy completed the onsite tie-in to the existing plant in 2011, all mechanical equipment for the recovery facility has been procured and compressor installation is planned for 2016. Pipeline construction is planned to commence in 2016 and be fully operational in 2017. Except for a 20 km / 12 mile, 12-inch diameter section in the Redwater area, the rest of the pipeline (220 km / 137 miles) will be 16-inches in diameter.
The CO2 captured from the Agrium plant will initially be transported via the ACTL to the Clive oil field in Central Alberta. The Clive field was discovered in the early 1950’s and has produced around 70 million barrels to date. The field presently produces 300 barrels of oil equivalent per day. Enhance Energy plans to recover additional light oil from the Nisku and Leduc reservoirs (at a depth of approximately 1,900 metres / 6,200 feet) through CO2 injection. The cap rocks of the Leduc and Nisku reservoirs are the shales of the Ireton and Calmar formations respectively. These cap rock shales are further capped by cretaceous sediments and coals that act as secondary barriers to CO2 migration. |
