Title (EN) HIGH-PRESSURE POLYMERIZATION PROCESS OF ETHYLENICALLY UNSATURATED MONOMERS IN A PRODUCTION LINE HAVING FLANGES COVERED BY A CHIMNEY CONSTRUCTION
(FR) PROCÉDÉ DE POLYMÉRISATION À HAUTE PRESSION DE MONOMÈRES ÉTHYLÉNIQUEMENT INSATURÉS DANS UNE CHAÎNE DE PRODUCTION AYANT DES BRIDES RECOUVERTES PAR UNE CONSTRUCTION DE CHEMINÉE
Abstract:
(EN) A process for polymerizing or copolymerizing ethylenically unsaturated monomers at pressures in the range of from 110 MPa to 500 MPa in a production line comprising a continuously operated polymerization reactor, wherein at least one of a pre-heater or pre-cooler, a polymerization reactor or a post reactor cooler is composed of tubes of a length from 5 m to 25 m which are flanged together, either directly or via bends, and the flanges are covered by a chimney construction, and wherein air is conveyed through the chimney construction and the air exiting the chimney construction is monitored with respect to the hydrocarbon concentration.
(FR) L'invention concerne un procédé de polymérisation ou de copolymérisation de monomères éthyléniquement insaturés à des pressions comprises entre 110 MPa et 500 MPa dans une chaîne de production comprenant un réacteur de polymérisation fonctionnant en continu, au moins l'un des éléments suivants, à savoir un préchauffeur ou un pré-refroidisseur, un réacteur de polymérisation ou un refroidisseur de post-réacteur étant composé de tubes d'une longueur de 5 à 25 mètres qui sont bridés ensemble, directement ou par l'intermédiaire de coudes, et les brides sont recouvertes par une construction de cheminée, de l'air étant acheminé le long de la construction de cheminée, et la concentration d'hydrocarbures dans l'air sortant de la construction de cheminée étant surveillée.
