Abstract

Two new flow apparatuses have been designed and constructed to determine vapour-liquid equilibria of very corrosive components. Main differences between the two apparatuses are their temperature and pressure ranges of operation. When using each of the two equipments, a monophasic mixture is introduced continuously at constant pressure into a thermostated equilibrium coil. The vapour and liquid leave the coil at equilibrium and enter a separator from which each phase is withdrawn continuously to maintain a constant level of the interface in the separator. Samples taken from the outcoming flows are analysed. The first apparatus (medium temperature-low pressure) was developed to test the new dynamic method. The experimental results we got for the system water- acetic acid are in good agreement with those of Othmer et al. (1952). The second apparatus for measurements up to 50 bar and 823 K was used to get SO-3-H-2O equilibrium data. The results obtained are presented, at low pressures they are in good agreement with tabulated data of Gmitro and Vermeulen (1963, 1964).
