High-Pressure Phase Equilibrium Tester
For measuring the temperature, pressure, and gas/liquid phase composition parameters of the phase equilibrium state of pure substances, binary, or ternary systems under high pressure (5MPa, 10MPa, or higher).
The XIATECH high-pressure phase equilibrium tester is used to measure the high-pressure phase equilibrium parameters of pure substances or mixed systems (binary or ternary). It obtains the temperature, pressure, liquid phase mole fraction x*, and gas phase mole fraction y* of the phase equilibrium state of mixed systems under high pressure (5MPa, 10MPa, 20MPa, or higher), assists in drawing multi-component phase diagrams, and provides reliable experimental data for complex high-pressure mixed systems. The equipment features advantages such as high temperature measurement accuracy, wide pressure measurement range, and precise measurement. Combined with independently developed programs, it can realize automatic temperature control, automatic pressure boosting, automatic sampling, and data analysis, and is particularly suitable for measuring phase equilibrium parameters of supercritical CO₂ and mixed systems such as N₂ and O₂ mixtures.
