(FR) REVÊTEMENT POUR RÉDUIRE LA COKÉFACTION ET AIDER À LA DÉCOKÉFACTION DANS UN ÉCHANGEUR DE CHALEUR DE LIGNE DE TRANSFERT
Abstract
(EN)
Coke formation in pyrolysis furnaces is controlled by applying a coating of boron nitride to pyrolysis furnace process equipment surfaces, for instance, parts of the transfer line heat exchanger assembly.
(FR)
Selon l'invention, la formation de coke dans des fours à pyrolyse est contrôlée par application d'un revêtement de nitrure de bore à des surfaces d'équipement de traitement de four à pyrolyse, par exemple, des parties de l'ensemble échangeur de chaleur de ligne de transfert.
