Vapor-Liquid-Liquid Equilibrium (VLLE) - Wolfram ... Aug 04, 2014 · This Demonstration shows phase equilibrium for a binary system of two partially miscible liquids, A and B. Because of the partial miscibility, vapor-liquid equilibrium (VLE), liquid-liquid equilibrium (LLE), and vapor-liquid-liquid equilibrium (VLLE) are present on the phase diagram. You can vary the mole fraction of component B and the heat ... Vapor Pressure - Georgia State University Saturated Vapor Pressure The process of evaporation in a closed container will proceed until there are as many molecules returning to the liquid as there are escaping. At this point the vapor is said to be saturated, and the pressure of that vapor (usually expressed in mmHg) is called the saturated vapor pressure.

vlle - LearnChemE Vapor-Liquid-Liquid-Equilibrium Description This is a simulation of phase equilibrium for one mole of a binary system (A, B) that forms two partially-miscible liquids (α, β). The T-x-y diagram shows vapor-liquid equilibrium (VLE), liquid-liquid equilibrium (LLE), and vapor-liquid-liquid equilibrium (VLLE). Vapor Liquid Equilibrium - Bucknell University Vapor-liquid equilibrium (known as VLE) is the state in which the rate of condensation is equal to the rate of evaporation so there is no net vapor-liquid interconversion ( Wikipedia ). Typically, a substance in vapor-liquid equilibrium is at its boiling point. A boiling point diagram for a binary mixture is found to the right. Vapor - Wikipedia Vapor refers to a gas phase at a temperature where the same substance can also exist in the liquid or solid state, below the critical temperature of the substance. (For example, water has a critical temperature of 374 °C (647 K), which is the highest temperature at which liquid water can exist.) If the vapor is in contact with a liquid or solid phase, the two phases will be in a state of ...
