摘要

A high-pressure, phase equilibrium analyzer incorporating a fiber-optic reflectometer is described. The analyzer has been designed for measuring the vapor-liquid equilibrium data of multi-component mixtures of carbon dioxide and permanent gases, providing a novel tool to acquire of a large number of phase equilibrium data for the development of the new carbon capture and storage technologies. We demonstrate that the analyzer is suitable for determining both the bubble-and dew-point lines at temperature from 253 K and pressure up to 25MPa using pure CO2 and two binary mixtures of CO2 + N-2 and CO2 + H-2.
