Title (EN) HIGH PRESSURE SEPARATOR CLEANING METHOD AND APPARATUS
(FR) PROCÉDÉ ET APPAREIL DE NETTOYAGE D'UN SÉPARATEUR HAUTE PRESSION
Abstract: front page image
(EN)A process and system for cleaning a high pressure separator vessel (100) in a polymerization reactor without removing the top cover (110) and its associated bolts by providing a cleaning hole (220) in a fluid fitting (120) above and adjacent to the top cover (110), through which a cord or cable (150) is fed and affixed to a rotatable cleaning nozzle (160). The cleaning nozzle (160) is gradually raised, lowered and rotated to direct a high pressure liquid onto the interior walls of the vessel to remove accumulated waste material.
(FR)L'invention concerne un procédé et un système de nettoyage d'un récipient (100) de séparateur haute pression dans un réacteur de polymérisation sans retirer le couvercle supérieur (110) et ses boulons associés par l'utilisation d'un trou de nettoyage (220) dans un raccord de fluide (120) au-dessus du couvercle supérieur (110) et à côté de celui-ci, à travers lequel un cordon ou un câble (150) est introduit et fixé à une buse (160) de nettoyage rotative. La buse (160) de nettoyage est progressivement élevée, abaissée et mise en rotation pour diriger un liquide haute pression sur les parois intérieures du récipient afin d'éliminer les déchets accumulés.
