摘要

超临界二氧化碳 (sCO2) 能从浮石中的盐水中去除水分，其去除率远高于水在 sCO2 中的溶解度。水在 sCO2 中的被动乳化和 sCO2 在饱和浮石中的粘性指状作用共同导致了较高的水去除率。这导致盐沉积的程度高于仅从溶解度考虑所预期的程度。这些沉积物可能会影响 sCO2 的注入能力及其在地下的移动。发现 sCO2 中的水浓度不一定在溶解度极限时封顶，这应影响注入模型的参数化。

Enhanced Removal of Brine From Porous Structures by Supercritical CO2

Supercritical CO₂ (sCO₂) removes water from brine held in pumice stone at levels well above the solubility of water in sCO₂. The higher water removal results from a combination of passive emulsification of water in sCO₂ and viscous fingering of sCO₂ through the saturated pumice. This leads to higher levels of salt deposition than that expected from solubility considerations alone. These deposits could impact the injectivity of sCO₂ as well as its movement in the subsurface. The finding that the water concentration in sCO₂ is not necessarily capped at the solubility limit should influence the parametrization of injection models.

期刊介绍： Ground Water is the leading international journal focused exclusively on ground water. Since 1963, Ground Water has published a dynamic mix of papers on topics related to ground water including ground water flow and well hydraulics, hydrogeochemistry and contaminant hydrogeology, application of geophysics, groundwater management and policy, and history of ground water hydrology. This is the journal you can count on to bring you the practical applications in ground water hydrology.
