VAPOR-LIQUID-EQUILIBRIA AT HIGH-TEMPERATURES AND PRESSURES IN BINARY-MIXTURES CONTAINING H-2, CH4 AND CO2 WITH HIGH BOILING HYDROCARBONS - EXPERIMENTAL EQUIPMENT AND RESULTS

An apparatus was designed, built and operated with the purpose of studying vapor-liquid equilibria at temperatures 450 < T < 650 K and pressures 1 < p < 35 MPa or critical pressure. The liquid in the high pressure equilibrium cell was agitated by a magnetically driven mixer. Samples can be taken from the vapor and the liquid phase. The composition was determined by a combination of gravimetric and volumetric measurements. Test measurements were performed on binary systems investigated previously by others in order to check the reproducibility and accuracy of the measurements.
