The NWR Partnership said the Sturgeon Refinery and Nutrien’s Redwater Fertilizer Facility capture and compress CO2 before pushing it south down … Initially, ACTL is expected to capture and sequester up to 1.8 megatonnes (Mt) of CO2 each year, the equivalent of taking 339,000 cars off the road, with the long-term potential of up to 15 Mt of CO2 annually. There was strong acceptance for the project due to several factors - consultation with a commitment to utilize existing infrastructure such as roads to the extent possible, and understanding of the economic and environmental benefits to the local communities and Alberta as a whole. The Sturgeon Refinery started pumping CO2 underground in June, while Shell’s Quest project near Fort Saskatchewan had trapped some 5 million tonnes of CO2 underground as of July. The entire unit heats feedstock under atmospheric and then vacuum conditions into various fractions for further processing. 2100, 350 7 Ave. SW The next challenge: transport the CO2 to the injection site some 240 kilometres to the south. Main Contractor Air Liquide Canada X Light Ends Recovery. The hydrocracker feed is vacuum distillate produced by both the Crude and Vacuum Unit and LC Finer Unit. Not all carbon dioxide is created equal. Comments on this story are moderated according to our Submission Guidelines. The HC Flare Unit ensures safe disposal of gases during Plant upsets. The Liquefied Petroleum Gas (LPG) from the Light Ends Recovery Unit is routed directly offsite. Our economies need to reach net-zero CO2 emissions if we want to prevent excessive global heating, Rajendran said. The pipeline has excess capacity, so in the future, more facilities and storage reservoirs can be added to the system. The CCS Global Institute reported that the number of large-scale CCUS facilities in operation increased to 21 with the announcement of the ACTL becoming fully operational. It became operational near the same time as the ACTL and, according to NWR Sturgeon Refinery CEO Ian MacGregor, it is the world’s only refinery designed from the ground up to minimize its environmental footprint through CCUS while producing the “high-value, low-carbon products needed to meet North America’s demand for energy.”, “We set out to make something valuable from bitumen—low-carbon diesel starting from high-carbon feedstock—and build the world’s largest carbon capture system,” he said. NWR has an agreement in place to supply its CO2 to an independent third party company, which has built the province’s first CO2 gathering and distribution pipeline, the Alberta Carbon Trunk Line (ACTL). This will be the largest CCUS project in Canada and the oil produced through CO2 EOR will be among the least carbon-intensive in the world. The Tankage Unit – or tank farm – consists of multiple tanks: These tanks provide a buffer for reliable refinery operation and a staging area for shipments of final product such as Ultra Low Sulphur Diesel, Unconverted Oil and Hydrocarbon condensate (Diluent and Naphtha). Post-combustion CO2 contains compounds and impurities that would have to be scrubbed (removed by heat, chemistry or both) to produce a cleaner gas — with associated costs and, ironically, more emissions. Our economies need to reach net-zero CO2 emissions if we want to … The Light Ends Recovery Unit converts waste gases produced by the Crude and Vacuum Unit, the LC Finer Unit, and the Hydro-Processing Unit into useable fuel gas for the refinery thereby reducing Natural Gas consumption. Since then, governing parties in the province have varied in their support for carbon capture projects: Critics of carbon capture projects argue the funding would be better spent on renewable energy to tackle climate change, while others say such projects may make people and industry complacent about reducing emissions. It integrates a one-step conversion process, the first of its kind, combining gasification, CO2 capture, and storage into the initial design. The decision to use gasification as an integral component of the refining process enables capture of a significant portion of CO2 (Carbon dioxide) in a simple process step. for operation of the refinery and the treatment of liquid effluent generated by the process units. The idea is to flood the reservoir with CO2, which acts like a solvent that reduces the viscosity of the remaining oil so it can be pumped to the surface. This in turn enables the production of high purity CO2 which is ideal for enhanced oil recovery (EOR). The Sturgeon Refinery also NWR Sturgeon Refinery is a 80,000 bbl/d (13,000 m /d) crude oil upgrader—built, owned and operated by North West Redwater Partnership (NWRP) in a public private partnership with the Alberta provincial government. Enhance Energy has sourced CO2 from two facilities in the Heartland region of Alberta (northeast of Edmonton) that produce the high-quality CO2 needed: the Sturgeon Refinery (the world’s only refinery designed to produce EOR-quality CO2) and Nutrien’s Redwater fertilizer plant. Comments are welcome while open. “As a strong advocate for CCUS technology, the Boilermakers union has been a major supporter of the ACTL efforts,” said Cory Channon, International Director of Climate Change Policy Solutions. As a result, the project has received all the necessary approvals. The talk was part of a partnership between the Edmonton Public Library and Future Energy Systems. As new high-quality CO2 sources are identified, Enhance Energy intends to use CO2 EOR on a number of other reservoirs in close proximity to the ACTL. Volume 59, Number 3 Another key benefit to this technology is that the entire process happens within the reactor, making it possible to capture all of the CO2 before it is released into the atmosphere. This puts the Sturgeon Refinery at the forefront of being a catalyst for the EOR industry in Alberta. While there’s a lot of interest in carbon capture, Rajendran said it faced stiff competition from wind and solar, which were far cheaper ways to reduce emissions. “I can’t remember how many times I’ve been told ‘it won’t work,’ but we never wavered. The residue is cracked under high pressure in the presence of hydrogen in a reactor. “CO2 capture is possible technologically,” Rajendran said, and has long been used by fertilizer plants to purify other gas streams (typically hydrogen). Context: Energy Examined aims to provide an engaging insider’s perspective for the public. The Intergovernmental Panel on Climate Change has said that in order to avoid the worst effects of climate change, the world needs to reach net-zero carbon emissions by 2050— that is, one molecule of CO2 has to be sequestered for every molecule emitted. Rajendran said his Wednesday talk was fully subscribed, but would later be posted to the Future Energy Systems YouTube channel. Kevin Ma joined the St. Albert Gazette in 2006. We think there is over one billion barrels of additional oil could be produced from previously developed reservoirs – oil that would not be recovered without CO2 EOR. Sulphur is typically used for fertilizer production. The project’s injection capacity is equivalent to about 20 per cent of all current oil sands emissions. Illustrating the alignment of innovation, partnerships and CCUS efforts, the NWR Sturgeon Refinery uses gasification to convert bitumen waste product into both the hydrogen required for refinery operations and a pure, dry CO2 stream that is cost-effectively captured instead of vented into the atmosphere, eliminating about 70% of the refinery’s total CO2 footprint. Sturgeon bitumen refinery phase 1 details. The Hydro-Processing Unit produces high quality products; Ultra Low Sulphur Diesel, Treated Naphtha and Unconverted Oil. Most CO2 is produced as a result of combustion — for example, burning natural gas to create the steam needed for bitumen extraction in the oil sands, or burning coal for electricity generation. To build the pipeline, Enhance Energy and partner Wolf Carbon Solutions (pipeline construction and operation) worked closely with landowners along the route and near the injection facility. Eddy concludes, “In a world that will need oil for generations to come, our industry is innovating to keep reducing emissions per barrel. It is located in Sturgeon County northeast of Edmonton, Alberta, in Alberta's Industrial Heartland. ALBERTA CARBON TRUNK LINE/Photo. The system has capacity for additional operations to be connected. That’s exactly the thinking behind Calgary-based startup Enhance Energy. What if you could recover more oil from an older reservoir, and permanently store waste carbon dioxide (CO2) safely underground at the same time? Currently, Alberta’s North West Redwater Partnership’s Sturgeon Refinery and Nutrien’s Redwater Fertilizer Facility are both capturing CO2 and supplying it into the ACTL, where it travels to a storage reservoir owned by Enhance Energy. Carbon capture projects are taking off in the Edmonton region. By submitting a comment, you accept that CBC has the right to reproduce and publish that comment in whole or in part, in any manner CBC chooses. Global use of fossil fuels isn't expected to dry up for decades and that's why some experts say carbon capture projects have the potential to ensure the oil and gas industry can be part of a net-zero world.

Worldwide, there are currently 21 CCUS facilities in operation, four under construction and 28 in development. Enhance Energy anticipates CO2 injection to begin in the first half of 2020, with oil recovery starting about six months later. The LC Finer Unit (or Residue Hydrocracker) hydrocracks (breaks) long chain carbon molecules to smaller ones and saturates them with Hydrogen. Right now, enhanced oil recovery (where you inject the gas underground to push up more oil) is one of the few ways to make carbon-capture economical. Enhance Energy is part of a consortium of companies that own and operate the ACTL system. This Unit treats the Unstabilized Diluent into high quality products that are then sent to market. “In Alberta, CO2 is a feedstock for a new downstream industry,” explained MacGregor. In 2014, Jim Prentice dismissed it as a "science experiment.". This feedstock is necessary to unlock the additional light oil trapped in nearly depleted reservoirs throughout Alberta. But it’s also expensive, and currently costs about $40 to $90 per tonne of CO2, he continued. Catalyst is also used in this process to ensure high yield and quality products. The feed for this process is Vacuum residue from the Vacuum and Distillation Unit. In the planning stages, NWR required a process to manufacture hydrogen while minimizing CO2 emissions and recognized the need to eliminate the heavy asphaltene residue generated as upgrading waste. “Those same geological characteristics will permanently lock the injected CO2 within the Clive reservoir. I feel very good about the outlook for the growth of this business," said Jeff Pearson, with Wolf Midstream, which operates the pipeline. This feedstock is necessary to unlock the additional light oil trapped in nearly depleted reservoirs throughout Alberta. Further, the injection process does not involve fracturing the reservoir rock. After more than a decade in the works, a new carbon capture project in Alberta is now operational with lofty goals of sequestering large amounts of emissions, while also helping to revitalize the oil industry in the central part of the province. The Hydro-Processing Unit upgrades the heavy oil to produce lighter and high quality products. Although Alberta has many reservoirs with the right geological characteristics to support CO2 injection, the issue is finding the right kind of CO2.”. The $1.2-billion project will take emissions from the Redwater Fertilizer factory and the Sturgeon refinery near Edmonton to aging oil reservoirs in central and southern Alberta.
