This Small Business Innovation Research (SBIR) Phase I project will prove the feasibility of using a photolytic process to separate carbon dioxide (CO2) from monoethanolamine (MEA) scrubbers for carbon capture in power plants. This innovation is based on verified studies showing that photolysis reactions are faster and use significantly less energy than thermal reactions. The carbon-capture process begins when MEA is used to scrub CO2 from flue gas. The CO2-rich MEA is then sent to a chamber where it is heated to 100-120 oC to remove CO2 for sequestration. Using the current state-of-the-art thermal process to capture CO2 in a coal-fired power plant requires burning 30 % more coal to produce the same amount of electricity, increasing the cost of energy by 81 %. By proposing to use a photolytic reaction to separate CO2 from MEA, Pearlhill is not just improving the current thermal reaction process, but taking CO2 separation technology in an entirely new direction with significant cost saving potential. The broader/commercial impact of this research could drastically reduce the massive energy demand to capture CO2 from power plant flue gas. Building on the current MEA technology has dual benefits. First, for existing coal-fired power plants where MEA technology is employed, Pearlhill?s photolytic process has the potential to be retrofitted, since only the thermal unit must be replaced. Second, using a photolytic instead of the energy-intensive thermal process could reduce the energy costs for carbon capture by over 30 %, saving power plants and ultimately end-users millions of dollars.

这个小型企业创新研究（SBIR）第一阶段项目将证明使用光解过程从单乙醇胺（MEA）洗涤器中分离二氧化碳（CO2）的可行性，用于发电厂的碳捕集。 这一创新是基于经过验证的研究，表明光解反应比热反应更快，使用的能源也少得多。 碳捕获过程开始于MEA用于从烟道气中洗涤CO2。 然后将富含CO2的MEA送到一个腔室中，在那里将其加热到100-120 oC以除去CO2用于封存。 在燃煤电厂中使用当前最先进的热过程来捕获二氧化碳，需要燃烧30%以上的煤来产生相同数量的电力，从而使能源成本增加81%。 通过提出使用光解反应从MEA中分离CO2，Pearlhill不仅改进了当前的热反应工艺，而且将CO2分离技术引入了一个全新的方向，具有显著的成本节约潜力。这项研究的更广泛/商业影响可以大大减少从发电厂烟气中捕获CO2的大量能源需求。 基于当前的MEA技术，有双重好处。 首先，对于采用MEA技术的现有燃煤电厂，Pearlhill？的光解过程有可能被改造，因为只有热单元必须更换。 其次，使用光解而不是能源密集型的热过程可以将碳捕获的能源成本降低30%以上，为发电厂和最终用户节省数百万美元。
