Product Details
1) Product Introduction
VLE2000high temperaturePhase balance testerDeveloped based on the principle of static method, specifically designed for the determination of gas-liquid phase equilibrium parameters under high temperature and high pressure conditions, its core uses mechanical stirring to promote the system to reach equilibrium state, and then utilizes high-precision micro; The rapid online sampler completes high-precision sampling of gas and liquid phases, effectively overcoming the technical difficulties of reasonable sampling in static analysis methods. While minimizing system equilibrium damage, it can accurately reflect the true gas-liquid phase composition in the equilibrium kettle. It has the characteristics of accurate measurement, high temperature measurement accuracy, and wide pressure measurement range. It is a powerful tool for phase equilibrium research under high temperature and high pressure conditions and is suitable for various binary systems/In terms of determining the core performance of gas-liquid equilibrium parameters for ternary systems, the equipment currently has a high temperature and high pressure measurement range and high-precision measurement capability, with a temperature measurement range covering room temperature~100°C, pressure range0.5~5 MPa(Both can be controlled)The temperature measurement accuracy is better than±0.02CThe temperature control fluctuation is stable at±0.05°CAt the same time, using a specifically designed measurement system can ensure that the temperature field of the mixed sample in the equilibrium kettle is highly uniform and stable, and can also guarantee the long-term stability of the mixed system during the testing process, providing a solid guarantee for the accuracy and repeatability of the measurement results.
VLE2000high temperaturePhase balance testerEquipped with an efficient automation control system, combined with self-developed programs, it can achieve full process automation operations, including automatic temperature control, automatic pressurization, automatic sampling, and data analysis, significantly reducing the cost of manual intervention. Its micro sampling technology supports high-precision quantitative sampling analysis with multiple injections, which not only shortens the experimental time but also ensures stable experimental results, further improving testing efficiency and data reliability.
This device is equipped with a safety protection system and built-in automatic pressure relief function, which can prevent pressure from exceeding the set upper eye, comprehensively ensuring experimental safety. It is used for testing pure, binary, and ternary systems, and can accurately obtain the temperature in equilibrium state(T)Pressure(P)Liquid phase mole fraction(x)Gas phase mole fraction(y)The four core parameters can also be expanded to obtain gas-liquid equilibrium phase diagrams, vapor pressure, boiling point and other data, meeting diverse research needs.
