The capture of carbon dioxide (CO2) is an important processing step for most natural gas processing plants, bio-gas processing units and petroleum refineries. It is also an essential process for chemical and energy production facilities such as hydrogen production plants, synthesis gas plants, biomass-gasification units, and oil-sand operations. These industrial processes are very important steps for the future production of clean energy and low-carbon fuels, which include bio-fuels. Also, the CO2 capture process is the most important component of the technology called Carbon Capture, Utilization and Storage (CCUS), which plays a key role in addressing the two important environmental problems of our time: (i) climate-change and (ii) energy security. An International Energy Agency (IEA) study reports that there is a significant opportunity of storing up to 360 Gt of CO2 through enhanced oil recovery (EOR) applications over the next 50 years. The EOR technology represents an opportunity to potentially increase oil production by up to 375 billion barrels. From the perspective of life cycle assessment, the total emission of CO2 per unit energy produced from the oil produced by CO2 EOR flooding is much less than that of natural gas. For example, the IEA Weyburn-Midale CO2 Monitoring and Storage Project, which constitutes the world's largest implementation of CO2 for EOR and CCUS technologies, has stored over 30 million tons of anthropogenic CO2 since 2000.      The ultimate goal of the proposed study is to develop a more effective CO2 capture process technology for industrial gas streams, with the lowest possible capital and operating costs, and minimal operating challenges. The primary objective is to investigate different methods for reducing the cost of CO2 separation by developing promising and novel formulated solvents for CO2 recovery using new and recently invented specialty amines. In the proposed research program, we will focus on studying these newly created amines and their formulated mixtures which include (i) 4-((2-hydroxyethyl)(methyl)amino)-2-butanol (HEMAB) and (ii) 4-((2-hydroxyethyl)(ethyl)amino)-2-butanol (HEEAB). Initial results show that these novel amines can provide much higher CO2 absorption capacities for CO2 removal than conventional amines. Novel solvent regeneration techniques, called the catalyst-aided method, together with the concept of proportional split flow for solvent regeneration, will also be used to further reduce the energy consumption. The knowledge obtained will contribute to our current understanding of these technologies, as well as form the basis for developing the future and more efficient generations of CO2 capture technologies. The new understanding will help the industry to achieve significant savings in both capital and operating costs of the CO2 capture and separation processes which can reduce the greenhouse gas and benefit our environment.

对于大多数天然气加工厂，生物燃料加工单元和石油炼油厂而言，二氧化碳（CO2）的捕获是重要的加工步骤。它也是化学和能源生产设施（例如氢生产厂，合成燃气厂，生物量加热单元和油砂运营）的重要过程。这些工业过程是未来生产清洁能源和低碳燃料（包括生物燃料）的非常重要的步骤。同样，二氧化碳捕获过程是该技术的最重要组成部分，称为碳捕获，利用和存储（CCUS），在解决我们时代的两个重要环境问题中起着关键作用：（i）气候变化和（ii）能源安全。一项国际能源机构（IEA）的研究报告说，在未来50年内，通过增强的石油回收（EOR）应用将有很大的机会存储多达360 GT的CO2。 EOR技术代表了可能将石油产量增加多达3750亿桶的机会。从生命周期评估的角度来看，由CO2 EOR洪水产生的石油产生的每单位能量的总排放量远低于天然气。例如，IEA Weyburn-Midale CO2监控和存储项目构成了世界上最大的EOR和CCUS技术的CO2实现，自2000年以来，已存储了超过3000万吨的人为CO2。自2000年以来，这项拟议的研究的最终目标是为工业气体促进了更有效的CACTERATION CACTORIAN CAPTARION CASSION CONCATION CASSICT PROCECTION CONECTION INDERTIAL GALEST APERTARIAL GESRAPERS与低位挑战，并可能成本，并且可能会构成质量成本，并可能成本，并可能成本，并构成了质量的资金。主要目的是通过开发新的和最近发明的特种胺通过开发诺言和新型配制的二氧化碳恢复解决方案来研究降低二氧化碳分离成本的不同方法。在拟议的研究计划中，我们将专注于研究这些新创建的胺及其配制的混合物，其中包括（i）4 - （（2-羟基乙基）（甲基）氨基）-2-丁醇（Hemab）和（ii）4-（（2-羟基乙基）（乙基）氨基）（乙基）氨基）-2-丁二醇（Heeab）。最初的结果表明，这些新型胺可以比常规胺提供更高的二氧化碳吸收能力以去除二氧化碳。新型的溶剂再生技术称为催化剂辅助方法，以及溶剂再生的比例分裂流的概念，也将用于进一步减少能源消耗。获得的知识将有助于我们当前对这些技术的理解，并构成发展未来和更有效的CO2捕获技术的基础。新的理解将有助于该行业在二氧化碳捕获和分离过程的资本和运营成本上大大节省，这可以减少温室气体并使我们的环境受益。
