Supercritical CO2 phase conversion experimental demonstrator SC-CO2-PT
  Test principle: Supercritical carbon dioxide is the supercritical state of carbon dioxide, that is, carbon dioxide changes with temperature and pressure, beyond the critical temperature, critical pressure, and critical volume state of carbon dioxide. The density and viscosity of dioxy carbon will increase with the increase of pre...

      超临界二氧化碳是二氧化碳的超临界状态,也就是二氧化碳随着温度和压力的变化,超出了二氧化碳气液的临界温度,临界压力,临界容积状态的二氧化碳。

      二氧人碳的密度和黏度,会随着压力的增加而变大,随着温度的升高而减小,压缩因子会随着温度,压力而变化,当温度高于31.1摄氏度,压力高于7.38Mpa时,二氧化碳便进入到了超临界状态,在二氧化碳地质储存中,大多数储层的温度和压力均达到了临界点以上,二氧化碳常常是以超临界状态储存于地质体中。

      超临界二氧化碳是一种高密度流体,在物理特性上兼有了气体和液体的双重特性,密度是气体的几百倍,近于液体,这也让超临界二氧化碳有很强的溶剂化能力,具有常规液态溶剂的强度,在临界温度以下,气体被不断的压缩会有液相出现,然而,超临界流体被压缩只是增加其密度,不会形成液相,超临界流体的密度和温度与压力密切相关,超临界二氧化碳的密度随着压力升高而增大,随着温度升高而减小,在临界点附近,密度对于压力和温度十分的敏感,很小的温压变化就会导致密度的急剧变化。
