Abstract
Researchers measured (Vapour + liquid) and (liquid + liquid) equilibria for (water + p-xylene) and (water + decalin) mixtures at T = (573 to 623) K by a flow type apparatus with microfluidic system. They used liquid–liquid slug flows in the microfluidic system to mix water and hydrocarbon because of high mass transfer between two liquid phases. They studied formations of the liquid–liquid slugs for (water + p-xylene) system by changing the flow rate.
They used results of the liquid–liquid slug formations at hydrocarbon and water rich compositions for the measurements for (vapour + liquid) and (liquid + liquid) equilibria, respectively.  They observed that the phase equilibria using the apparatus with the microfluidic system can be measured in a short residential time.
