Abstract
One exemplary embodiment is a refinery or a petrochemical production facility. The refinery or petrochemical production facility can include: a) a catalyst regeneration zone; b) a halogen removal zone; and c) an elimination zone for at least one of a dioxin and a furan compound, wherein at least a portion of an effluent from the halogen removal zone is combined with a stream comprising oxygen from the catalyst regeneration zone or halogen removal zone.
Claims20
A process for removing at least one of a dioxin and a furan, comprising:
- a) passing a first stream from a catalyst regeneration zone comprising halogen and at least one of a dioxin and a furan through a halogen removal zone comprising an adsorbent to adsorb at least one halogen;
- and
- b) combining the first stream from the halogen removal zone with a second stream from a heater from the catalyst regeneration zone or a cooler for the first stream to obtain a combined stream at a temperature of above about 150° C. and an oxygen content no less than about 1%.
A process for catalytically removing at least one of a dioxin and a furan, comprising combining a first stream from a halogen removal zone with a second stream comprising at least a portion of a heater discharge stream from a catalyst regeneration zone or a coolant stream for the first stream to obtain a combined stream to pass through an elimination zone to remove at least a portion of at least one of a dioxin and a furan.
A refinery or a petrochemical production facility, comprising:
- a) a catalyst regeneration zone;
- b) a halogen removal zone;
- and
- c) an elimination zone for at least one of a dioxin and a furan compound, wherein at least a portion of an effluent from the halogen removal zone is combined with a stream comprising oxygen from the catalyst regeneration zone or halogen removal zone.
