The Ebert and Panchal fouling model was used to assess the fouling tendency of the exchangers of an industrial crude distillation unit (CDU) preheat train. The ranking obtained through a monitoring and processing of the performances of the different exchangers matched quite well the predictions of the Ebert and Panchal fouling model. In the meantime, a first mitigation solution consisted in periodically cleaning heat exchangers and installing TURBOTALTM tube inserts. Through the fouling monitoring of the equipped exchangers, the beneficial action of the TURBOTALTM inserts is also made quite clear.
