Fossil fuel is a major energy resource in Canada, and the Canadian economy is highly dependent on the energy sector. Also, most of the world's energy (over 85%) comes from fossil fuels. Unfortunately, the use of fossil fuels produces CO2, which is a green house gas and is believed to be a major contributor to climate change. This poses a special challenge for Canada. However, while Canada generates large amounts of CO2 from large point sources such as coal power plants exhaust gases, and off-gases of petrochemical plants, petroleum refining, oil upgrading, etc., possibilities exist for sequestering the CO2 produced in geological formations, in some cases such as in Western Canada, for enhanced oil recovery (EOR). Thus, to overcome CO2 emission problems, there is great interest in capturing the CO2 and using it for EOR processes. Presently, the main obstacle to the capture and sequestration option is the high cost of CO2 capture. This is associated with the large amount of energy used for the capture process as well as operational issues such as corrosion of construction material and degradation of the chemical (amine solvent) used in CO2 capture, both of which are caused partly by the presence of impurities in the exhaust or off-gases. The proposed research will drastically minimize all these operational problems. The objective is to develop a novel chemical as well as an additive that will be formulated into an energy efficient amine solvent for CO2 capture. This novel energy efficient solvent will not only minimize the energy required for the CO2 capture process, but also, will simultaneously inhibit both corrosion and degradation when the formulated solvent is used for CO2 capture from the exhaust or off-gases. This will reduce operating costs considerably. Also, the inhibition of corrosion implies that cheaper material can be used for construction thereby resulting in much lower capital costs. The overall research will therefore result in the development of a much lower cost process for CO2 capture, which will ensure that Canada continues to use its fossil fuel resources, but in an environmentally sustainable manner.

化石燃料是加拿大的主要能源，加拿大经济高度依赖能源部门。同样，世界上大多数能量（超过85％）来自化石燃料。不幸的是，化石燃料的使用会产生二氧化碳，这是一种温室气体，被认为是导致气候变化的主要贡献者。这对加拿大提出了一个特别的挑战。但是，尽管加拿大从大点来源产生了大量的二氧化碳，例如煤炭发电厂的排气气体以及石化植物的瓦式，石油炼油，石油升级等可能性，但在某些情况下，在加拿大西部（例如在加拿大西部）中，存在隔离地质地层中生产的二氧化碳的可能性，以增强油的回收（EOR）。因此，为了克服二氧化碳排放问题，对捕获二氧化碳并将其用于EOR过程引起了极大的兴趣。目前，捕获和隔离选项的主要障碍是二氧化碳捕获的高成本。这与用于捕获过程的大量能量以及操作问题有关，例如建筑材料的腐蚀和二氧化碳捕获中使用的化学物质（胺溶剂）降解，这两者部分是由于排气或偏离剂中存在杂质而引起的。拟议的研究将大大最大程度地减少所有这些操作问题。目的是开发一种新型的化学物质和添加剂，该化学物质将被配制成节能胺溶剂以捕获CO2。这种新型的节能溶剂不仅可以最大程度地减少二氧化碳捕获过程所需的能量，而且当使用配制的溶剂用于从排气或离子中捕获CO2时，同时抑制腐蚀和降解。这将大大降低运营成本。此外，抑制腐蚀意味着可以将较便宜的材料用于施工，从而导致资本成本更低。因此，总体研究将导致开发二氧化碳捕获的成本较低的过程，这将确保加拿大继续使用其化石燃料资源，但以环境可持续的方式。
