Title (EN) ENHANCEMENT OF CLAUS TAIL GAS TREATMENT BY SULFUR DIOXIDE-SELECTIVE MEMBRANE TECHNOLOGY
(FR) AMÉLIORATION DU TRAITEMENT DE GAZ RÉSIDUAIRE DE CLAUS PAR TECHNOLOGIE À MEMBRANE SÉLECTIVE AU DIOXYDE DE SOUFRE
Abstract:
(EN) A method for increasing sulfur recovery from an acid gas feed comprising the steps of introducing the acid gas feed and a sulfur dioxide enriched air stream to a Claus process to produce a product gas stream, introducing the product gas stream to a thermal oxidizer to produce a flue gas stream, cooling the flue gas stream to produce a cooled take-off stream, separating the cooled take-off stream into a saturated gas stream, heating the saturated gas stream to produce a membrane gas stream, introducing the membrane gas stream to a membrane sweeping unit, the membrane sweeping unit comprises a membrane, the sulfur dioxide in the membrane gas stream permeates the membrane of the membrane sweeping unit, introducing a sweep air stream, the sweep air stream collects the sulfur dioxide to create the sulfur dioxide enriched air stream.
(FR) Un procédé pour augmenter la récupération de soufre à partir d'une alimentation en gaz acide comprend les étapes consistant à introduire l'alimentation en gaz acide et un flux d'air enrichi en dioxyde de soufre dans un processus Claus pour produire un flux de gaz produit, à introduire le flux de gaz produit dans un oxydant thermique pour produire un flux de gaz de combustion, à refroidir le flux de gaz de combustion pour produire un flux de soutirage refroidi, à séparer le flux de soutirage refroidi en un flux de gaz saturé, à chauffer le flux de gaz saturé pour produire un flux de gaz de membrane, à introduire le flux de gaz de membrane dans une unité de balayage de membrane, l'unité de balayage de membrane comprenant une membrane, le dioxyde de soufre dans le flux de gaz de membrane passe à travers la membrane de l'unité de balayage à membrane, à introduire un flux d'air de balayage, le flux d'air de balayage collecte le dioxyde de soufre pour créer le flux d'air enrichi en dioxyde de soufre.
