Zusammenfassung:	A methodology and system is disclosed which addresses outstanding needs of refiners to process cheaper crudes or blends of crudes. This method and system comprises a number of steps, including characterizing the impact of various constituents in the crude which result in fouling of heat exchangers; estimating model parameters; monitoring and predicting qualitative and quantitative performance; and determining optimal dosage of chemical treatments. La présente invention concerne une méthodologie et un système qui s'adressent aux besoins importants des raffineurs de traiter des bruts moins chers ou des mélanges de bruts. Cette méthode et ce système comprennent un certain nombre d'étapes, comprenant la caractérisation de l'impact de divers constituants dans le brut qui résultent en l'encrassement des échangeurs thermiques ; l'estimation des paramètres modèles ; le suivi et la prédiction de la performance qualitative et quantitative ; et la détermination du dosage optimal des traitements chimiques.
