Vapour liquid equilibrium

Processium : vapour liquid equilibrium

Vapour liquid equilibrium (abbreviation VLE) is a State where a liquid and its vapour (gas phase) are in equilibrium, a condition or a State where the rate of evaporation (liquid becoming vapour) is equal to the rate of condensing (vapour becoming liquid) under specific conditions where no net vapour liquid interconversion intervenes.

These concentration data  of vapour liquid equilibrium can be determined experimentally for mixtures of various components or for pure compounds. In some cases, these data of vapour liquid equilibrium can be determined or assimilated to some theories as the Raoult, Dalton, or Henry’s Law. These vapour liquid equilibrium information are useful in designing and improving industrial processes and in the design of distillation columns considering differences between the composition of liquid and gas phases. You are interested in physical properties measurement and especially in vapour liquid equilibria. 

Ask for our powerful tools, our platform dedicated to the physical properties (modelling, database, and laboratory) and our proven expertise. We can conduct multiple tests in our laboratory (eg. precise measurements of boiling point with an ebulliometer developed in our laboratory) to determine these thermodynamic properties (boiling point, vapour pressure, vapour liquid equilibrium, liquid liquid equilibrium, solubility of gases, mutual solubility, heat capacity Cp, activity coefficient at infinite dilution, Henry coefficient, azeotropic composition, enthalpy of vaporization, critical properties...).
