In thermodynamics and chemical engineering, the vapor–liquid equilibrium (VLE) describes the distribution of a chemical species between the vapor phase and a liquid phase.

2025年1月25日 · Draw vapor-liquid equilibrium (VLE) and liquid-miscibility (LLE) phase diagrams, or calculate distillation processes. Over 300 organic compounds.

Steam-liquid equilibrium apparatus . Knowledge of the vapour-liquid equilibrium data (VLE) of a system is the basis for all distillative separation processes of liquid mixtures.

2023年9月1日 · Vapor-liquid equilibria (VLE) of hydrocarbon solvents and steam binary mixture are important for the feasibility studies of the solvent-aided thermal recovery of bitumen. In this …

2022年4月1日 · Both processes use steam as an excellent heat carrier (Liu et al., 2020). As steam is injected into the reservoir and releases its latent heat, the viscosity of the oil …

VLE# class VLE (imol = None, thermal_condition = None, thermo = None) [source] # Create a VLE object that performs vapor-liquid equilibrium when called. Parameters: imol=None …

Simply stated, we say that a system is at steady state when whatever comes into the system goes out. This is, no accumulation takes place within the system. Let us consider the equilibrium cell …

2024年4月3日 · The Dortmund Data Bank has four separate data banks which all contain vapor-liquid equilibrium data. The VLE and the HPV databanks both contain exactly the same data …

VLE is most commonly used for H 2 O (steam / water) calculations. Please see Water and Steam Properties for information about the equations used in SysCAD for H 2 O. If the species model …
