    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.
