    摘要: Processes are provided for conjointly producing Br2, a concentrated aqueous solution containing CaCI2, and Cl2 from an aqueous HBr-rich stream and a feed brine dilute in CaCI2 that 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 Cl2 from a Cl2 source, at least a portion of which is produced according to this invention, to produce Br2, recovering Br2 from the tower, removing a bromide-depleted bottoms from the tower, such bottoms containing HCI, adding a Ca++ source to the bromide-depleted bottoms to convert substantially all of the HCI in the bottoms to CaCI2, as necessary, removing water from the treated bottoms to produce the concentrated aqueous solution, producing Cl2 and caustics from residual chlorides such as NaCI, and using at least a portion of the thus produced Cl2 in the Cl2 source.

    摘要: Processes are provided for conjointly producing Br2 and a concentrated aqueous solution containing at least about 5 wt % CaCI2, based on the weight of the concentrated aqueous solution, from an aqueous HBr rich stream and, optionally, a feed brine dilute in CaCI2. Such processes can comprise feeding the aqueous HBr-rich stream and the feed brine to a tower, oxidizing bromide moieties within the tower with Cl2 to produce Br2, recovering Br2 from the tower, removing a bromide-depleted bottoms from the tower, such bottoms containing HCI, adding a Ca++ source to the bromide-depleted bottoms to convert substantially all of the HCI in the bottoms to CaCI2, and, as necessary, removing water from the treated bottoms to produce the concentrated aqueous solution.
