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，化石燃料的使用会产生二氧化碳，这是一种温室气体，被认为是气候变化的主要贡献者。这对加拿大来说是一个特殊的挑战。然而，尽管加拿大从大量点源产生大量二氧化碳，如燃煤电厂废气和石化厂废气、炼油、石油提质等，但存在隔离地质构造产生的二氧化碳的可能性，在某些情况下，例如在加拿大西部，以提高石油采收率(EOR)。因此，为了克服二氧化碳排放问题，人们对捕获二氧化碳并将其用于三次采油过程非常感兴趣。目前，捕获和封存选择的主要障碍是二氧化碳捕获的高昂成本。这与捕获过程使用的大量能源以及建筑材料腐蚀和二氧化碳捕获中使用的化学物质(胺溶剂)降解等操作问题有关，这两个问题的部分原因都是废气或尾气中存在杂质。拟议的研究将极大地减少所有这些操作问题。其目标是开发一种新的化学品以及一种添加剂，这种添加剂将被配制成一种用于捕获二氧化碳的能效胺类溶剂。这种新型的高能效溶剂不仅将二氧化碳捕获过程所需的能量降至最低，而且在使用配方溶剂从废气或尾气中捕获二氧化碳时，还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来建造，从而导致更低的资本成本。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。

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.
