Development of a common corrosion and degradation inhibitor additive for formulation of a novel energy efficient solvent for carbon dioxide capture from industrial gas streams

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。此外，世界上大部分能源（超过85%）来自化石燃料。不幸的是，化石燃料的使用产生二氧化碳，这是一种绿色家用气体，被认为是气候变化的主要因素。这对加拿大来说是一个特殊的挑战。然而，虽然加拿大从大型点源（如燃煤发电厂废气和石化厂、石油炼制、石油升级等的废气）产生大量CO2，在某些情况下，例如在加拿大西部，存在隔离地质构造中产生的CO2用于提高石油采收率（EOR）的可能性。因此，为了克服CO2排放问题，人们对捕获CO2并将其用于EOR工艺非常感兴趣。目前，捕获和封存方案的主要障碍是CO2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（例如，构造材料的腐蚀和用于CO2捕获的化学品（胺溶剂）的降解）相关，这两者都部分地由废气或废气中的杂质的存在引起。拟议的研究将大大减少所有这些操作问题。目的是开发一种新型化学品以及添加剂，将其配制成用于CO2捕获的节能胺溶剂。这种新型节能溶剂不仅将使CO2捕集过程所需的能量最小化，而且当配制的溶剂用于从废气或尾气中捕集CO2时，将同时抑制腐蚀和降解。这将大大降低运营成本。此外，腐蚀的抑制意味着可以使用更便宜的材料进行构造，从而导致低得多的资本成本。因此，总体研究将导致开发一种成本低得多的二氧化碳捕获工艺，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。

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.
