Title (EN) REGENERABLE SULFUR ADSORPTION AND REMOVAL
(FR) ADSORPTION ET ÉLIMINATION DE SOUFRE RÉGÉNÉRABLE
Abstract:
(EN) A method for the removal of sulfur from a sulfide adsorbent comprises contacting the sulfide-containing gas stream with a zinc oxide-based adsorbent, desulfurizing the gas stream while sulfiding the adsorbent and regenerating the sulfided adsorbent by treatment with steam or steam enriched with oxygen at an elevated temperature. This way the adsorbent is converted back to zinc oxide.
(FR) L'invention concerne un procédé pour l'élimination de soufre d'un adsorbant de sulfures comprenant l'entrée en contact du flux gazeux contenant des sulfures avec un adsorbant à base d'oxyde de zinc, la désulfuration du flux gazeux lors de la sulfuration de l'adsorbant et la régénération de l'adsorbant sulfuré par un traitement avec de la vapeur ou de la vapeur enrichie en oxygène à une température élevée. De cette manière, l'adsorbant est reconverti en oxyde de zinc.
