Managing Hydrate Formation for Viable CO2 and Energy Transport

增加二氧化碳管道输送过程中允许的含水量将大大提高碳捕获和储存的可行性，但也会增加二氧化碳水合物堵塞的风险。如果能够避免生产管道堵塞，海底甲烷水合物沉积物将成为一种巨大的新能源资源。传统的石油工业避免水合物的方法相关性有限，而且对于这些新应用来说过于昂贵。测量CO2和CH4水合物的形成概率分布、粘结力和团聚倾向，并将其整合到预测多相流模型中，实现对CO2输送或水合物生产管道堵塞的定量风险评估。

Increasing the allowable water content during the pipeline transportation of carbon dioxide (CO2) would greatly increase the viability of carbon capture and storage but would also increase the risk of CO2-hydrate blockages. Subsea methane (CH4) hydrate sediments represent a tremendous new energy resource if blockages in production pipelines can be avoided. Conventional oil industry approaches to hydrate avoidance are of limited relevance and too expensive for these new applications. Formation probability distributions, cohesive forces and agglomeration tendencies of CO2 and CH4 hydrates are intended to be measured and integrated into predictive multi-phase flow models, enabling quantitative risk assessments of blockages in CO2 transport or hydrate production pipelines.
