Abstract—

A device was designed to measure the solubility of carbon dioxide in hydrocarbons at temperatures up to 473 K and pressures up to 25 MPa. It can be used to study the solubility of CO₂ at state parameters that are supercritical for CO₂ in the presence of a porous medium in the oil reservoir model and in the absence of it. The results of the experiments on measuring the solubility of carbon dioxide in kerosene are described using the Peng–Robinson equation of state. This technique for measuring the solubility both of CO₂ in a hydrocarbon and of a hydrocarbon in CO₂ in the mode of dynamic filtration in a porous medium can be applied in power engineering and machine building to study changes in the thermophysical and physicochemical properties of hydrocarbons.

在宽工作温度和压力范围内研究二氧化碳在烃中溶解度的实验装置

摘要—

设计了一种装置，用于在温度高达473 K和压力高达25 MPa的情况下测量二氧化碳在烃类中的溶解度。它可以用于研究在油藏模型中是否存在多孔介质以及是否存在多孔介质的情况下，CO ₂在状态参数（对于CO ₂超临界）下的溶解度。使用彭-罗宾逊状态方程描述了测量二氧化碳在煤油中的溶解度的实验结果。该用于测量CO ₂在烃中和烃在CO _2中的溶解度的技术 在多孔介质中进行动态过滤的方法可以应用于动力工程和机械制造，以研究碳氢化合物的热物理和物理化学性质的变化。
