  • Publication number: 20130295001
    Abstract: 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.

  • Publication number: 20130287675
    Abstract: A new, highly selective way of removing bromine contamination from a gaseous stream comprised of hydrogen bromide and bromine is described. Such process technology involves non-catalyzed free radical (benzylic) bromination of an alkylene-bridged aromatic hydrocarbon and/or certain alkyl-substituted aromatic hydrocarbons and recovering the purified gaseous HBr. Because of the high selectivity of the bromination on the aliphatic bridges or side-chains, virtually no ring bromination occurs, and this enables recovery of the bromine values in the form of HBr. Thus preferably, the bromine is recovered as HBr from the scrubbing liquid by subjecting the scrubbing liquid to thermal or catalytic dehyrobromination. In plant operations, the gaseous HBr purified in the process can then be introduced into a compressor to produce either liquid or gaseous HBr for storage under pressure. Alternatively, the purified gaseous HBr can be fed directly into one or more reactions in which HBr is used as a reactant.

  • Publication number: 20130189379
    Abstract: Described are highly concentrated liquid biocidal solutions formed in water from (a) specified bromine sources (e.g., BrC1 or mixtures of BrC1 and Br2) and (b) alkali metal salt of sulfamic acid and/or sulfamic acid and alkali metal base, wherein the solution contains >160,000 ppm of active bromine. Solutions of this type have been found to have greater stability than a commercially-available solution made from the same components containing 148,600 ppm of active bromine. Also described are new, water-soluble, solid state biocidal products formed by removing the water from solutions made in water from (a) and (b) irrespective of the initial concentration of active bromine. Removal of water can be accomplished by flashing or distillation at reduced pressure or preferably by spray drying. Such solid state products are typically in the form of powders or small particles, but can be compacted into larger forms preferably with the aid of one or more suitable binding agents.
