摘要： SO3 is formed from a replenished circulating inventory of fresh and recycled SO2. Also, a feed stream of replenished SO2 is heated by indirect heat exchange with a hot stream of SO2 and SO3 whereby the hot stream is cooled for separating the two gases. The heated feed stream of replenished SO2 serves as a hot gaseous feed to a sulfur burner. This SO2 feed is divided into two feed streams, one being oxygenated with pure oxygen and the other remains as an SO2 feed. These feeds plus a feed of molten sulfur are concurrently and separately introduced into the sulfur burner where additional SO2 is formed via continuous exothermic reaction. Although heated, the oxygenated feed(s) of SO2 bring in the needed oxygen for the reaction and the feeds of the oxygenated and non-oxygenated SO2 serve as a heat sink in the sulfur burner to reduce the temperature therein.

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 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. Such processes can comprise feeding the HBr-rich recycle stream and a liquid comprising a portion of the feed brine, either together or separately to an HBr absorption tower; producing an aqueous HBr-rich stream in the HBr absorption tower; feeding the aqueous HBr-rich stream and, optionally, a portion of the feed brine to a bromine tower, oxidizing bromide moieties within the bromine tower with CI2 to produce Br2; recovering Br2 from the bromine tower, removing a bromide-depleted bottoms from the bromine 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.
