Nottingham see this research as the opportunity to start the full research into a complicated combination of compressor technology and CO2 behaviour. As such it is the first stage of two, and will establish the likely behaviour of a centrifugal, barrel pump type compressor and examine the likely effects of impurities in the gas on the behaviour during compression. This opportunity to work alongside a major manufacturer of high pressure-high volume compressors for methane delivery and a major supplier of power plant consultancy and turnkey power plant puts UK research at the forefront of a high need technology. Current demands and future predictions indicate that CO2 capture and long term storage in depleted oil and gas wells is set to increase. It will require a novel compressor technology to do it effectively, since the behaviour of CO2 is particularly complicated by its transition to the super critical state over the required pressure range. Additional unknown complexity is introduced by impurities in the exhaust combustion gas stream. Compression is done in a number of stages to satisfy the demands of the Laws of Thermodynamics, the required machine efficiency and the particular thermodynamic characteristics of the fluid. A single stage will be modelled in the first instance, requiring high speed rotating flow modelling together with compressibility effects of the fluid that is worked upon. This extremely demanding computational modelling work therefore requires at this stage a mechanical engineering project to model the un-measurable characteristics of a CO2 compressor starting with a current pump design used for methane, to establish the modelling technique. It also requires a chemical engineering project to gather all the current knowledge on CO2 compression and delivery and the effects on the gas of including impurities as the various pressure stages are passed through. This combination of effort will then be driven forward to produce a model of the whole process, by projection of single stage modelling, to model the overall effect of processing the CO2. The two post doctoral researchers will be joined by a post graduate researcher on a PhD, who will work on the mechanical side over three years, investigating the more fundamental characteristics of the fluid behaviour in computational models. This key person will, by the time the other two reserch contracts have finished, be in a strong position to continue the work and to link to the second stage of the work. The aim of the overall project with industrial partners is to not be limited by current technology. Nottingham is very interested in assessing the effect of impurities in CO2. The work package 1 review of literature will find out what real testing should be done for the next stage of the work. With interstage cooling there are potential gains. Together we are looking to second generation compressor development, and this first stage of that work will develop the basic principles for a second stage project which proposes to conduct experimental investigation together with further numerical development of a practical application.

诺丁汉大学将这项研究视为开始对压缩机技术和二氧化碳行为的复杂组合进行全面研究的机会。因此，这是两个阶段中的第一个阶段，并将建立离心桶泵式压缩机的可能行为，并检查气体中杂质对压缩过程中行为的可能影响。有机会与一家主要的高压-高容量甲烷输送压缩机制造商和一家主要的电厂咨询和交钥匙电厂供应商合作，使英国的研究处于高需求技术的前沿。目前的需求和未来的预测表明，在枯竭的油气井中，二氧化碳的捕获和长期储存将会增加。这将需要一种新的压缩机技术来有效地做到这一点，因为二氧化碳在所需压力范围内过渡到超临界状态时的行为特别复杂。额外的未知复杂性是由废气燃烧气流中的杂质引入的。压缩分几个阶段进行，以满足热力学定律的要求，所需的机器效率和流体的特定热力学特性。首先将对单级进行建模，需要高速旋转流动建模以及所处理流体的可压缩性效应。因此，在这个阶段，这项极其苛刻的计算建模工作需要一个机械工程项目，从目前用于甲烷的泵设计开始，对CO2压缩机的不可测量特性进行建模，以建立建模技术。它还需要一个化学工程项目，收集所有关于二氧化碳压缩和输送的现有知识，以及在不同压力阶段通过时对气体的影响，包括杂质。然后，这些努力的结合将被推动，通过单阶段建模的投影，产生整个过程的模型，以模拟处理二氧化碳的总体效果。两位博士后研究员将加入一位博士研究生研究员，他将在机械方面工作三年，研究计算模型中流体行为的更基本特征。当其他两份研究合同完成时，这个关键人物将处于一个强有力的位置，可以继续这项工作，并与第二阶段的工作联系起来。整个项目与工业合作伙伴的目标是不受当前技术的限制。诺丁汉大学对评估二氧化碳中杂质的影响非常感兴趣。工作包1对文献的回顾将找出在下一阶段的工作中应该做哪些真正的测试。级间冷却有潜在的好处。我们正在共同研究第二代压缩机的开发，该工作的第一阶段将为第二阶段项目制定基本原则，该项目建议进行实验研究，并进一步进行实际应用的数值开发。
