SBIR Phase II: Split Amine Absorbent for CO2 Capture from Post Combustion Flue Gas of Coal Fired Power Plants

这个小企业创新研究（SBIR）二期项目旨在展示一种新的低成本、低能耗的二氧化碳捕获技术。二氧化碳捕集与封存的成功依赖于低成本、低能耗的二氧化碳分离系统的开发。这一过程被称为分裂胺吸收，能够显著降低二氧化碳捕获成本。第二阶段的目标是评价从燃烧后燃煤电厂的烟气中捕集二氧化碳的技术的技术和经济可行性。方法是：1)测试先前开发的实验规模模型，2)设计并安装原型中试规模系统，并操作、测试、收集数据并优化其性能。该系统将作为滑流装置安装在现有的燃煤电厂中。它的设计目标是达到至少90%的二氧化碳去除效率。收集的数据将用于评价该技术的技术和经济可行性。该项目的更广泛的影响/商业潜力是为减少燃煤电厂的二氧化碳排放节省大量成本。与目前最先进的单乙醇胺（MEA）技术相比，该技术能够将二氧化碳捕获成本降低85%。降低这一成本是使煤炭成为经济上可行、社会上可接受的发电燃料的关键。

This Small Business Innovation Research (SBIR) Phase II project is designed to demonstrate a novel low cost and low energy-consuming CO2 capture technology. The success of CO2 capture and sequestration rely on the development of cost-effective and low energy-consuming CO2 separation system. The process, called Split Amine Absorption, is able to significantly reduce the CO2 capture cost. The Phase II objective is to evaluate the technical and economic viability of the technology for the CO2 capture from flue gas of post combustion coal fired power plants. The approach is to: 1) test previously developed bench-scale models and 2) design and install a prototype pilot scale system and operate, test, collect data, and optimize its performance. The system will be installed as a slipstream unit in an existing coal fired power plant. It will be designed to achieve at least 90% CO2 removal efficiency. The data collected will be used to evaluate the technical and economic viability of the technology.The broader impact/commercial potential of this project is significant cost savings for the reduction of CO2 emissions from coal-fired power plants. In comparison with today's state-of-art monoethanolamine (MEA) technology, the proposed technology is able to reduce the cost of CO2 capture by 85%. Reducing this cost is the key to making coal an economically viable and socially acceptable fuel for generating electricity.
