File Information

This is a simple class definition for an Antoine object to facilitate computation of pure component saturation temperatures and pressures. An object corresponding to a pure component is instantiated by specifying the Antoine parameters. Methods include the computation of saturation pressure, saturation temperature, and plotting.
Sample data is included for a small number of compounds. A search method is included to facilitate search the NIST Chemistry Webbook for Antoine parameters for other compounds.

An extensive tutorial demonstrates the use of Antoine's equation for vapor-liquid equilibrium calculations. Examples include bubble point and dew point calculations, the construction of binary Txy and xy diagrams, and the solution of isothermal flash problems.

This was developed for use in introductory courses in Chemical Engineering.

Required Products MATLAB
MATLAB release MATLAB 7.11 (R2010b)
MATLAB Search Path
Other requirements Requires at least Matlab 7.6 for classdef feature.

Close to what i am looking for.

05 Dec 2010 1.1

Added a plotting function, a sample database for pure components, and an extensive tutorial on the use of Antoine's equation for vapor-liquid calculations.

07 Dec 2010 1.2

Added data for additional compounds, and added methods for searching the NIST Chemistry Webbook for Antoine parameters. Significantly revised the internal documentation and tutorial.

07 Dec 2010 1.3


07 Dec 2010 1.4

Methods added for searching the NIST Chemistry Webbook for Antoine parameters. The tutorial and internal documentation has been significantly enhanced. Some minor bug fixes.

06 Dec 2014 1.5

Update to the Matlab Toolbox format.
