Major emitters in Canada face increasing pressure to implement CO2 capture - capturing carbon dioxide (CO2) from large point sources and storing it instead of releasing it into the atmosphere.
Applications separating CO2 and other sour/acid gases in large industrial plants are currently widespread, however CO2 removal for capture/sequestration is not common.
The technology is nearly mature. CO2 capture processes have been used to obtain commercially useful amounts of CO2 from flue gas streams, but not on a large scale. The challenge is in producing concentrated, high pressure CO2 from low pressure flue gas with low concentrations of CO2. 
In addition to stakeholder demands, new Canadian government regulations are being developed that require companies to show incremental improvements in efficiency based on CO2 emitted on an annual basis starting in 2011. Oilsands upgraders and SAGD facilities built after 2012 will be required to use carbon capture and storage before 2018. The regulations will also require fixed emissions caps planned for 2020, requiring a 20% reduction in GHG emissions from 2006 levels.
Extensive Experience & Innovative Execution
After 25 years of EPC excellence in the energy industry, Bantrel is applying our knowledgeable resource base to the growing frontier of CO2 capture and storage. Our leading-edge approach leverages the world-class front-end capabilities of our strong team of process engineers, the additional resources and expertise of our parent organization Bechtel, and our extensive experience in ULSD. We are also leveraging our experience in brownfield revamps and CO2 capture studies, along with our proven performance in health, safety and environmental stewardship.
Bantrel’s approach is two-fold: Applying existing technologies such as amine contacting/regeneration that are currently used in gas treating to CO2 capture, and investigating emerging processes that will be the workhorse technologies of CO2 capture in the near future.
Selecting the right technology for a specific application (selective H2S/CO2 separation) to achieve the best overall technical and economic solution can be challenging. Bantrel and Bechtel's CO2 separation experience is considerable.
Our experience in hydrogen sulphide and carbon dioxide removal includes two commercial integrated gasification combined cycle (IGCC) plants and numerous acid gas removal facilities associated with chemical plants, in addition to our experience in brownfield ULSD revamps. Bantrel and Bechtel are also currently working together on various initiatives, including studies and design basis initiatives for CO2 capture.
Bantrel, through our robust and integrated work processes, and extensive upgrading and refinery experience, has the ability and knowledge to execute CO2 capture projects for new and existing facilities of any scale.
