项目摘要

Canada benefits tremendously from its fossil fuel resources, deriving revenues from crude oil royalties, taxes, and sales of petroleum leases. In addition, there is associated employment and economic activity derived from the oil patch. On the other hand, Canada's energy utilization rate per capita is one of the highest in the world because Canada is a large northern country with a dispersed population base. Also, the majority of current and increasing energy needs is supplied by burning of fossil fuels, which have high carbon intensities, and their extraction and processing are not only very energy intensive, but also have a major impact on the environment. In particular, energy production from fossil fuels has recently been shown to be the key contributor of carbon dioxide (CO2), a major greenhouse gas (GHG), which has a direct influence on climate change and global warming. Currently, there is a huge challenge in finding a solution that will allow Canada to benefit from its large fossil fuel resources in an environmentally sustainable manner as a clean fuel. CO2 capture and storage (CCS) is a major component of the approaches that can be used to address this challenge. However, the main obstacle to this approach is that it is currently not efficient because of large energy penalty and plant size, leading to a high cost for CO2 capture. Recently, we have developed a novel, breakthrough, game-changing catalyst-aided amine-based technology that achieves a dramatic reduction in energy requirements and temperature for solvent regeneration, and the potential for a large reduction in equipment size. This low temperature enables the use of hot water for solvent regeneration, and creates the possibility for the CO2 capture plant to be used as a cooling tower for the electrical power plant. These are to drastically reduce the cost of CO2 capture. However, there are additional challenges as some of the more energy efficient amine solvents used in the operation could generate nitrosamines, a harmful by-product of the CO2 capture process. Nitrosamine formation could also lead to amine degradation and the deactivation of the catalysts used in the operation. This research will develop the strategies and operating process configuration that can use the best catalysts and the most energy efficient amine solvents to achieve the best performance in CO2 capture without any adverse results. This research will help to train and maintain a strong CO2 capture qualified personnel in Canada. It will also help to significantly improve the new catalyst-aided amine-based CO2 capture process leading to its implementation by industry. Further, it will lead to huge savings in capital and operating costs in CO2 capture thereby making a business case for CCS and increasing economic activities. In addition, it will lead to energy security for Canada enabling them to exploit their rich fossil fuel resources in an environmentally sustainable way.

加拿大从化石燃料资源中受益匪浅，从原油特许权使用费，税收和石油租赁的销售中获得收入。此外，还有从石油补丁中获得的相关就业和经济活动。另一方面，加拿大的人均能源利用率是世界上最高的能源之一，因为加拿大是一个大型北部国家，人口基础。同样，大多数当前和不断增长的能源需求都是通过燃烧具有高碳强度的化石燃料来提供的，其提取和加工不仅能量强度很高，而且对环境产生了重大影响。特别是，最近已证明来自化石燃料的能源生产是二氧化碳（CO2）的主要贡献者，二氧化碳（CO2）是一种主要的温室气体（GHG），对气候变化和全球变暖有直接影响。目前，找到解决方案的挑战是一个巨大的挑战，该解决方案将使加拿大以环境可持续的方式从其大型化石燃料资源中受益，作为一种干净的燃料。 CO2捕获和存储（CCS）是可用于应对此挑战的方法的主要组成部分。但是，这种方法的主要障碍是，由于能源损失和植物尺寸较大，目前效率不高，导致二氧化碳捕获的成本很高。最近，我们开发了一种新颖的，突破性的，改变游戏规则的基于催化剂的胺技术，该技术可显着降低溶剂再生的能量需求和温度，并有可能大大降低设备尺寸。这种低温使使用热水用于溶剂再生，并为二氧化碳捕获厂用作电厂的冷却塔而创造了可能性。这些是要大幅度降低二氧化碳捕获的成本。但是，由于操作中使用的一些更节能的胺溶剂可能会产生硝基胺，这是二氧化碳捕获过程的有害副产品，因此还有其他挑战。硝基胺的形成也可能导致胺降解和操作中使用的催化剂的失活。这项研究将开发策略和操作过程配置，这些策略和操作过程配置可以使用最佳的催化剂和最节能的胺溶剂来实现二氧化碳捕获中最佳性能，而不会产生任何不良结果。这项研究将有助于培训和维持加拿大强大的二氧化碳占领人员。它还将有助于大大改善新的基于催化剂的胺二氧化碳捕获过程，从而导致其行业实施。此外，这将导致二氧化碳捕获中的资本和运营成本大量节省，从而为CCS提供商业案例并增加经济活动。此外，加拿大将使他们能够以环境可持续的方式利用丰富的化石燃料资源。
