Abstract

Processes are provided for conjointly producing Br, a concentrated aqueous solution containing CaCI, and Clfrom an aqueous HBr-rich stream and a feed brine dilute in CaCIthat comprises NaCI. Such processes can comprise feeding the aqueous HBr-rich stream and the feed brine to a tower, oxidizing bromide moieties within the tower with Clfrom a Clsource, at least a portion of which is produced according to this invention, to produce Br, recovering Brfrom the tower, removing a bromide-depleted bottoms from the tower, such bottoms containing HCI, adding a Casource to the bromide-depleted bottoms to convert substantially all of the HCI in the bottoms to CaCI, as necessary, removing water from the treated bottoms to produce the concentrated aqueous solution, producing Cland caustics from residual chlorides such as NaCI, and using at least a portion of the thus produced Clin the Clsource.
