Utilisation de mesures de points critiques pour la caractérisation de nouveaux réfrigérants et la modélisation d'un procédé de synthèse de biodiesel

Abstract : Knowledge of mixture critical data is not only important for the design and the improvement of chemical processes but also to extend the range of applicability of predictive equations of state. However, mixture critical data comprise only a small percentage of the fluid phase equilibria data available in the open literature. This is the reason why it was decided to acquire a new synthetic-dynamic apparatus capable of determining the critical points of pure substances and multi-component mixtures. In a first step, the validation of the experimental procedure for critical point measurements was performed by comparing the experimental results obtained in this work with literature data. In a second step, the application of mixture critical data to the development of two types of process: i) biodiesel production via supercritical process and ii) phase behaviour of new refrigerants is presented. The experimental critical points measured in this work were also used for determining new group interaction parameters of the PPR78 model
