Title
(EN) SULFUR REMOVAL
(FR) ELIMINATION DU SOUFRE
Abstract
(EN)
A process for reducing the amount of down time or yield loss associated with a sulfur upset when using a sulfur-sensitive catalyst. The process comprises applying a metallic coat, cladding, plating or paint to a reactor system which comprises a base metal, so as to form an adherent metallic layer on the base metal and thereby produce a metal-coated reactor system; loading a sulfur-sensitive catalyst into the system; and, after a sulfur upset, using a process comprising sulfur stripping to remove sulfur contaminants from the metal-coated reactor system.
(FR)
Procédé permettant de réduire le temps d'immobilisation ou la perte de rendement associé au refoulement du soufre lorsqu'on utilise un catalyseur sensible au soufre. Ce procédé consiste à appliquer un revêtement, un placage, une couche ou une peinture métalliques sur un système de réacteur qui comprend un métal de base de manière à former une couche métallique adhérente sur le métal de base et à produire ainsi un système de réacteur recouvert de métal; à charger un catalyseur sensible au soufre dans le système; puis, après un refoulement de soufre, à utiliser un procédé comprenant l'extraction du soufre pour éliminer les contaminants soufrés du système de réacteur recouvert de métal.
