| Abstract: | A new-type vapor liquid phase equilibrium apparatus was introduced for low temperature equilibrium measurements.This advanced experimental rig can be carried out over a wide temperature range from 108.15 to 313.15 K with an accuracy of 10mK and pressures up to 50MPa,even its relative error can reach 0.01% with an extra Mensor pressure transducer of 0-10MPa range.In order to check the reliability and accuracy of the entire phase equilibria system,several test measurements had been performed on the saturation pressure of C2H6 and CH4 and VLE data of C2H6 C3H8,The results show good agreements with the reference data. |
