This Small Business Innovation Research Phase I project is to demonstrate an innovative low cost, low energy-consuming, and novel CO2 capture technology based on a process entitled ?Split Amine Absorption?. The Phase I objective is to develop data necessary to confirm the principle of the concept and to identify at least one set of optimum absorbent composition for the CO2 capture from flue gas of post combustion coal fired power plants. The approach to accomplishing the objective consists of: 1) continue bench-scale experiments (Phase I); 2) design and install a prototype pilot scale system and to 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 (Phase II).The broader impacts of this research are significant reduction of the cost of CO2 capture. The cost of capture and sequestration will be over 200 billions U.S. Dollars a year with current MEA amine-based technologies. The cost for CO2 capture alone accounts for more than 75 percent of the total cost of capture, transportation, and storage. Reducing this cost is the key to make coal an economically viable and socially acceptable fuel for generating electricity.

这个小企业创新研究第一阶段项目是为了展示一种创新的低成本、低能耗和新颖的二氧化碳捕获技术，该技术基于一个名为？分裂胺吸收？第一阶段的目标是开发必要的数据，以确认这一概念的原理，并确定至少一套最佳吸收剂组成，用于从燃烧后燃煤发电厂的烟气中捕获二氧化碳。实现目标的方法包括：1)继续进行实验规模的实验（第一阶段）；2)设计和安装一个原型中试规模的系统，并操作，测试，收集数据和优化其性能。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（第二阶段）。这项研究更广泛的影响是显著降低了二氧化碳捕获的成本。按照目前的MEA胺基技术，捕集和封存的成本每年将超过2000亿美元。仅二氧化碳捕获的成本就占捕获、运输和储存总成本的75%以上。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。
