VLE - Vapor Liquid Equilibria of Normal Boiling Substances

The VLE data file is the oldest and one of the largest data collections in the DDB. It contains different types of complete (x,y,P,T) or incomplete data for components with a normal boiling point above 0°C. Data reported in form of Henry or other coefficients are not included. These can be found in the GLE data bank. Although the data bank also includes some molten salt and molten metal data, mixtures with electrolytes (solvated ions) are not included. These can be found in the ELE, EGLE and ESLE data banks.

The 2013 version of the VLE data bank contains 34116 data sets for 1856 components from 7022 references and 10459 different systems (8569 binary, 1652 ternary and 252 quaternary systems).

For comparison:

  • The 2012 version of the VLE data bank contains 32860 data sets for 1810 components from 6806 references and 10171 different systems (8353 binary, 1587 ternary and 153 quaternary systems).
  • The 2011 version contained 'only' 31649 data sets for 1773 components from 6634 references and 9917 different systems (8156 binary, 1536 ternary and 149 quaternary systems).

This data bank is considered the most important by many customers.

Due to the importance of VLE data, e.g. for the design and simulation of distillation columns, VLE data have long since also been measured in-house by different companies. The DDB-VLE data file contains more than 1000 proprietary data sets from chemical industry that have never been published in the open literature. These data are often of great technical interest.

A part of the VLE data has been published in a standardized form within the very popular DECHEMA Chemistry Data Series - Vapor-Liquid Equilibrium Data Collection (starting 1975).

A typical data table output for a binary data set (ethanol - water) is given below. A typical graphical representation for the system chloroform - methanol is shown above.

DDB-VLE is a very good example of the consistent and accelerating growth of the DDB. The straight line correlation in the logarithmic plot below proves the exponential growth of the data file for a period of more than 37 years (Moore's Law applied to VLE data):
