Reducing Flow Measurement Uncertainties Through Accurate Determination of Thermophysical Properties of H2 and CO2 rich Fluid Mixtures

碳捕获、利用和封存(CCUS)和氢气生产是两个最可行和最直接的工程解决方案，可以在工业规模上使我们的地球实现净零碳(NZ)。除了目前以高成本建造新的CCUS设施的努力外，还可以通过重新利用已达到商业寿命的现有石油和天然气基础设施，作为二氧化碳和氢气运输和储存网络的一部分，提高这种脱碳进程的商业可行性。同样的再利用原则也可以应用于先进的资产管理工具和许多其他设备，如用于托管转移应用的流量测量设备。但是，在生产设施、集散站、利用设施和封存(对于LiqScritCO2)或存储(对于LiqCryoH2)基础设施中的流体生产和运输及其托管转移需要详细了解流体的热物理性质。目前，对于CO2捕集装置或制氢装置排出的丰富的LiqSritCO2和LiqCryoH2混合流，目前还缺乏全面的认识和了解。这些全面的知识对于设计、开发、测试和生产安全、准确地运行二氧化碳和氢气网络基础设施的合适技术至关重要。特别是，为了通过流量保证了解和确保其安全运营，以及吸引投资、交易和税收，减少不确定性的准确测量至关重要。这将为企业投资创造信心，同时还允许政府补贴或税收的统一和准确应用。作为一家负责任的企业，OGM正在投资将其突破性的数量测量(流量测量)和质量测量(混合和采样)设备重新用于二氧化碳和氢气经济。该项目将为OGM提供来自A4I合作伙伴的备受欢迎的专业知识，以开发合适且准确的热物理性质或状态方程(EOS)模型，并将其作为开放和便携的计算库进行后续实施，以便我们可以将其封装在计算流体力学(CFD)模拟工具中，该模拟工具将被开发为我们的超声流量计(UFM)的框架Digital-Twin。开发的工具将用于优化、验证和重新调整我们的UFM用于H2和CCUS经济托管转移计量应用。这种创新的方法可以在未来的产品开发、测试和验证中常规使用--更快、更便宜，而且碳足迹也要小得多。

Carbon capture, utilization and sequestration (CCUS) and Hydrogen Production are the two most viable and immediate engineering solutions to decarbonize our planet at industrial scale towards net-zero (NZ). In addition to the current effort to build new CCUS facilities at high cost, the commercial viability of such decarbonization process could be enhanced by repurposing existing oil and gas infrastructure that have reached the end of their commercial life as part of the CO2 and H2 transport and storage networks. The same repurposing principle could also be applied for advanced asset management tools and many other equipment such as flow measurement devices for custody transfer applications.However, fluid production and transport and its custody transfer at production facilities, gathering stations, utilization facilities and sequestration (for LiqScritCO2) or storage (for LiqCryoH2) infrastructure require detail understanding of the fluid thermophysical properties. Currently, there is practically no comprehensive knowledge and understanding on rich mixture streams of LiqScritCO2 and LiqCryoH2 coming out from CO2 capture or H2 production facilities. Such comprehensive knowledge is vital to design, develop, test and productize suitable technologies to operate the CO2 and H2 network infrastructure safely and accurately. In particular, to understand and ensure its safe operations through flow assurance as well as to attract investment, transaction and taxation, accurate measurement with reduced uncertainties is crucial. This will create confidence for businesses to invest while it also allows for government subsidies or taxations to be applied uniformly and accurately.As a responsible business, OGM is investing to repurpose its ground breaking quantity measurement (flow metering) and quality measurement (mixing and sampling) devices for the CO2 and H2 economy. This project will provide OGM the highly sought after expertise from an A4I partner to develop suitable and accurate thermophysical properties or equation of state (EoS) model and its subsequent implementation as an open and portable computational library so that we can encapsulate it in the computational fluid dynamics (CFD) simulation tools that will be developed to serve as a framework Digital-Twin for our Ultrasonic Flow Meter (UFM).The developed tools in turn will be used to optimize, validate and repurpose our UFM for the H2 and CCUS economy custody transfer metering applications. This innovative approach could be used routinely in future product development, testing and validation - faster, cheaper and with significantly smaller carbon footprint too.
