Equilibres liquide vapeur et construction de Mc Cabe et Thiele

ChemSOF est un site qui propose quelques applications (applets) java en ligne, en relation avec le Génie chimique. Bien que l'ensemble soit en anglais, l'usage en est aisé.

J'ai notamment testé l'application Binary VLE calculator, qui permet de tracer en quelques minutes les courbes d'équilibre liquide vapeur (isobares, isothermes, et y=f(x)), la construction de Mac Cabe et Thiele en rectification continue avec un taux de reflux donné, pour déterminer le nombre d'étages théoriques, et ce pour une vingtaine de mélanges binaires prédéfinis (mélange idéal, azéotrope).

Cette application peut notamment servir à résoudre des exercices de rectification comme ceux proposés sur le site www.azprocede.fr.

Binary VLE Calculator
Binary VLE Calculator plots Vapor Liquid Equilibrium diagrams like Pxy, Txy, xy for binary mixtures for both Ideal and Non-Ideal system. It also calculate stages based on Mc-Cabe Thiele method for separation of binary mixture.

Heat Exchanger Rating
Heat Exchanger Rating Calculator
Heat Exchanger Rating Calculator does the Rating for a Shell and Tube Heat Exchanger using Bell Delaware method. It evaluates the thermo-hydraulic performance of a fully specified exchanger.

Vertical Thermosyphon Reboiler Calculator (New)
Vertical Thermosyphon Reboiler Calculator does the simulation and rating calculation for a vertical thermosyphoning reboiler based on Chen's correlation.

Multi-component Flash Calculator
Multi-Component Flash Calculator
Multi-Component Flash Calculator does the normal VLE Flash calculations like BUBBLE P, DEW P, BUBBLE T, DEW T and P-T Flash. It uses Modified Raoult's law with Wilson Interaction parameters for Liquid non-ideality, Soave Redlich Kwong (SRK) and Peng Robinson (PR) EOS.

Pipe Flow Calculator
Pipe Flow Calculator simulates flow of liquid and gases through a piping network. It analyzes and solves a wide range of problems where the flow and pressure losses throughout a pipe network must be determined.
