CONFIGURATIONS ET PROCÉDÉS POUR L'ENRICHISSEMENT EN OXYGÈNE AVANCÉ POUR LA RÉCUPÉRATION DE SOUFRE

摘要

Advanced oxygen enrichment technologies for Claus plants are presented that provide an oxygen rich gas stream to the Claus burner of the thermal stage and one or more oxygen rich bypass gas streams to at least one of the catalytic stages to so increase the capacity of the plant while reducing the amount of recycle gases needed for flame temperature moderation.
