Corrosion Prediction in Residual CO2 Streams: Shifting the Paradigm

具有成本效益的碳捕集与封存（CCS）为实现2015年12月第21届缔约方会议达成的《巴黎协定》目标提供了一种选择。虽然在开发捕获和储存技术方面做出了重大努力，但迄今为止，两地之间的运输受到的关注较少。含有大量可能杂质的致密相和超临界CO2混合物的行为尚不清楚。准确预测这些混合物的物理性质和腐蚀潜力，将需要具有成本效益的设计和捕获和处理系统的操作。该项目的总体目标是改进物理性质和腐蚀速率的预测工具，并根据实验室和现场数据证明其准确性，以增加信心，并获得行业对所做预测的认可。实验框架将为模型的腐蚀相关方面提供必要的输入，而相平衡模型将能够描述精确的条件。

Cost-effective Carbon Capture and Storage (CCS) offers one option for meeting the goals of the ParisAgreement, reached at COP 21 in December 2015. Whilst there have been major efforts to developtechnologies for capture and storage, transportation between the two points has received less attention todate. The behaviour of dense phase and supercritical CO2 mixtures containing a large amount of possibleimpurities is not well understood. Accurate predictions of the physical properties and corrosion potential ofthese mixtures will be needed for the cost-effective design and operation of both capture and disposal systems.The overall goal of this project is to improve the predictive tools for both physical properties and corrosionrates and to demonstrate their accuracy against laboratory and field data in order to increase the confidenceand gain industry acceptance of the predictions being made. An experimental framework will provide thenecessary inputs for the corrosion-related aspects of the model, whilst the phase equilibria model will enableexact conditions to be described.
