FOCUS Fundamentals Optimised Capture Using

项目摘要

We aim to establish a formal collaboration between the University of Edinburgh and North China Electric Power University to build upon the research excellence in carbon capture at both institutions, and to develop a novel process based on circulating new solid materials that will take up CO2 from fossil fuel combustion products and then release it as a pure stream that can be compressed and stored. The target is to reduce the energy requirement for capturing CO2 by 25-50% compared to current technologies, a significant reduction in additional fuel use and hence costs. The objectives of this research programme are to:1. Establish a vigorous collaboration between leading UK and Chinese research groups in the development of carbon capture technologies.2. Develop novel solids that take up CO2 by a combination of physical and chemical processes.3. Advance the understanding of ways in which these particles can be moved around in CO2 capture units attached to power stations4. Establish ways to combine experimental results and modelling at plant scale down to minute pore scale to obtain reliable modelling predictions for capture units5. Predict the performance of these novel carbon capture processes when they are added on to coal fired power stations operating in a realistic wayFor objective 2 different types of silicas as well as different amines will be developed as materials for CO2 adsorption at NCEPU. Their stability will be evaluated by thermogravimetric analysis (TGA) at the UoE. Samples of adsorbents will be ranked in terms of CO2 capacity using the rapid screening technique based on the zero length column (ZLC) method developed at the UoE as part of US-DOE and EPSRC-funded research. The technique needs only 10 mg of adsorbent and is therefore ideal for the early stages of development. The group at the UoE will host a researcher from NCEPU for a month to provide training and give assistance so that a similar system can be implemented at NCEPU. At NCEPU the pelletised materials will be used to generate breakthrough curves using CO2/N2 mixtures with and without water. These experiments will also be used to evaluate the potential for regeneration of the adsorbent using a purge stream which would significantly reduce the energy consumption for the process. Repeated adsorption/desorption cycles will be used to evaluate the stability of the materials over time. In 3, in order to be able to understand fully the performance of circulating fluidised beds of the novel capture materials UoE will perform solid circulation rate and gas tracer residence-time experiments using air as the fluidising gas, and resins, sand and adsorbent pellets for the particles. To gain further detailed insight into particle flows, the CFBs will be tested at the Positron Emission Particle Tracking (PEPT) facility in Birmingham. The detailed experimental results will form the basis for testing computational fluid dynamic (CFD) models developed at NCEPU and the UoE.To meet objective 4 NCEPU and the UoE will collaborate on extending large-scale computer particle flow modelling to include the effect of changes in the density of the particles due to adsorption and desorption. The resulting CFD code will be tested on the individual sections to evaluate the ability to describe the different flow regimes. A very small scale model for the description of combined mass and heat transfer in the adsorbent materials will be implemented and used to interpret the kinetic ZLC experiments. These models will then be combined to evaluate which capture equipment configuration works best in terms of separation efficiency and energy requirements. Throughout the project in order to meet objective 5 the work on the novel adsorption process will be coupled to work on novel power plant integration concepts. Both Chinese and UK partners have extensive power industry experience and can ensure that the research is relevant for real applications.

我们的目标是在爱丁堡大学和北中国电力大学之间建立正式合作，以两所机构在碳捕获方面的卓越研究成果为基础，并开发一种基于循环新固体材料的新工艺，该工艺将从化石燃料燃烧产品中吸收二氧化碳，然后将其作为可压缩和存储的纯流释放。其目标是与目前的技术相比，将捕获二氧化碳所需的能源减少25%-50%，从而显著减少额外的燃料使用，从而降低成本。这项研究计划的目标是：1.在英国和中国领先的研究小组之间建立强有力的合作，开发碳捕获技术。开发通过物理和化学过程相结合的吸收二氧化碳的新型固体。增进对这些颗粒如何在电站所附的二氧化碳捕集器中四处移动的理解4。建立将实验结果和从植物尺度到微孔尺度的建模相结合的方法，以获得捕获单元的可靠建模预测5。预测将这些新型碳捕获技术添加到以实际方式运行的燃煤电厂时的性能。为实现目标2，NCEPU将开发不同类型的二氧化硅和不同的胺作为二氧化碳吸附材料。它们的稳定性将通过热重分析(TGA)在UOE进行评估。作为美国能源部和EPSRC资助的研究的一部分，UOE将使用基于零长度柱(ZLC)方法的快速筛选技术对吸附剂样品进行二氧化碳容量排名。这项技术只需要10毫克的吸附剂，因此是开发早期阶段的理想选择。UOE的小组将接待一名来自NCEPU的研究人员，为期一个月，提供培训和援助，以便NCEPU能够实施类似的系统。在NCEPU，造粒材料将被用来在有水和不有水的情况下使用二氧化碳/氮气混合物来产生穿透曲线。这些实验还将用于评估使用吹扫气流再生吸附剂的潜力，这将大大减少该过程的能源消耗。重复的吸附/解吸循环将被用来评估材料随时间的稳定性。为了能够全面了解新型捕集材料循环流态化床的性能，UOE将以空气为流态化气体，以树脂、沙子和吸附颗粒为对象，进行固体循环速度和气体示踪剂停留时间实验。为了进一步深入了解粒子流动，CFB将在伯明翰的正电子发射粒子跟踪(PEPT)设施中进行测试。详细的实验结果将成为测试NCEPU和UE开发的计算流体力学(CFD)模型的基础。为了满足目标4，NCEPU和UOE将合作扩展大规模计算机颗粒流模拟，以包括因吸附和解吸而导致的颗粒密度变化的影响。生成的CFD程序将在各个截面上进行测试，以评估描述不同流型的能力。将实现一个描述吸附材料中质量和热联合传递的非常小比例的模型，并用于解释动力学ZLC实验。然后，将结合这些模型来评估哪种捕获设备配置在分离效率和能量需求方面工作得最好。在整个项目中，为了实现目标5，关于新型吸附工艺的工作将与新型发电厂集成概念的工作相结合。中英两国的合作伙伴都拥有丰富的电力行业经验，可以确保研究与实际应用相关。
