Method and equipment for determining the isobaric vapor-liquid-liquid equilibrium in heterogeneous systems.

摘要

Method and equipment for determining the isobaric vapor-liquid-liquid equilibrium in heterogeneous systems. Starting from a standard equipment for determining the liquid-vapor in homogeneous systems equilibrium, the invention involves applying ultrasound to the liquid-liquid-vapor mixture through an ultrasonic probe (7) connected to a tube (5) welded to the boiler (1) and communicating therewith, leaving the leading end of the tube (5) and the operating end (8) of the probe (7), located within the boiler (1) to the level of the duct (3) that relates to the flask mixer (2), also adopting said tube (5) and the probe (7) a direction of minimum inclination with respect to the imaginary axis of the boiler (1), and also establishing between the probe (7) and the tube (5) a seal to prevent leakage of liquid and / or steam with the least loss of acoustic energy transmitted to the liquid.
