Résumé

Synthetic refrigerants (freons), in case of leakage from the Installation, they cause the ozone layer destruction and increase the greenhouse effect. In order to minimize these global threats, it is necessary to detect these substances emissions as soon as possible. The aim of this work was to develop a new analysis method for selected fluorinated and chlorofluorocarbons mixtures using a gas chromatograph with cooling system (liquid CO2) and FID detector. The impact of various parameters and analysis conditions on the synthetic refrigerants mixtures separation was examined at low temperature conditions. The optimization of the most important parameters of the chromatographic method, which allows for the separation of commercial refrigerants mixtures (R402a, R404a, R409A, R407c, R410a, R413a, R507 and R422d), was carried out. The best chromatographic selection of the model mixture (eleven component synthetic refrigerants) has been obtained for the isothermal method. The chromatographic method for the low-temperature analysis of the refrigerants, using the FID detector and the cooling system, has a high potential for practical application for the separation of commercial refrigerants mixtures.
