UKCCSRC Call 2 project poster: CO2 Flow Metering through Multi-Modal Sensing and Statistical Data Fusion, CSLF Call project poster reception, London, 27.06.16

This poster on the UKCCSRC Call 2 project CO2 Flow Metering through Multi-Modal Sensing and Statistical Data Fusion was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C2-218. Measurement and monitoring of CO2 flows across the Carbon Capture and Storage (CCS) chain are essential to ensure accurate accounting of captured CO2 and help prevent leaking during transportation to storage sites. The significant changes in physical properties of CO2 depending on its state (gas, liquid, two-phase or supercritical) mean that CO2 flows in CCS pipelines are complex by their nature. Meanwhile, impurities in a CO2 pipeline also make the flow more likely in the form of two-phase mixture. Despite difficulties due to the changes in CO2 properties, there has been very little research into metering issues of CO2 flows. The aim of this project is to develop a cutting-edge technology for CO2 flows metering in CCS pipelines. The objectives are as follows: • To establish a mass reference platform for CO2 flowmeter calibration; • To develop a prototype multi-modal sensing system and data fusion algorithms for mass flow metering of CO2; • To evaluate the performance of the multi-modal sensing system under single-phase and two-phase CO2 flow conditions.

本海报展示了关于英国碳捕集与封存研究、开发与示范中心（UKCCSRC）第二阶段项目——通过多模态传感与统计数据融合进行二氧化碳流量计量的研究。该研究在2016年6月27日于伦敦举行的CSLF项目海报招待会上展出。项目编号：UKCCSRC-C2-218。在碳捕集与封存（CCS）链中二氧化碳流量的测量与监控对于确保捕获的二氧化碳准确计量以及防止在运输至储存地点过程中的泄漏至关重要。二氧化碳的物理性质（气态、液态、两相或超临界状态）随状态变化而发生的显著变化，使得CCS管道中的二氧化碳流量本质上具有复杂性。同时，二氧化碳管道中的杂质也使得流量更可能以两相混合物的形式存在。尽管二氧化碳性质的变动带来了诸多困难，但关于二氧化碳流量计量问题的研究却极为有限。本项目的目标是为CCS管道中的二氧化碳流量计量开发一项尖端技术。具体目标如下：
• 建立二氧化碳流量计校准的质量参考平台；
• 开发一种原型多模态传感系统及数据融合算法，以实现对二氧化碳质量流量的计量；
• 评估多模态传感系统在单相和两相二氧化碳流量条件下的性能。
