Abstract: 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 HBr-rich recycle stream and a feed brine dilute in CaCI2. wherein the aqueous HBr-rich stream is produced from an HBr-rich recycle stream and a portion of the feed brine.

Abstract: 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.

Abstract: 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.

Abstract: Synthetic zeolite is produced by force feeding separate aqueous streams of sodium silicate and of an alkali metal aluminate into coaxial alignment with each other. The coaxially aligned solutions are then introduced into in an open space in coaxial fashion with one of the streams being injected from a nozzle. The open space constitutes a mixing zone in which the two streams come together and are thoroughly mixed to produce a precrystallized mixture. This mixture then passes in unimpeded fashion through an entrance port and into a crystallization reactor or vessel. The system used for conducting this operation thus serves the dual function of being a feeding system and a mixing system whereby the silicate and aluminate streams interact with each other before entering the crystallization reactor or zone. Intimate mixing is assured by virtue of the relatively small volume of the mixing zone and the higher velocity of the stream emanating from the nozzle.
