Document Type and Number:
Japanese Patent JP2977825
Kind Code:
B2
Abstract:
Hydrogen bromide is produced by igniting a hydrogen/oxidant flame, replacing the oxidant with bromine vapor while maintaining a stable flame, cooling the combustion gases and recovering hydrogen bromide gas. Hydrogen bromide manufacturing equipment comprises a burner (1) which is supplied with bromine and/or oxidant (2) and with hydrogen (3) and which consists of a vertical tube within a vertical enclosure having a sequence of a cylindrical zone, a convergent frustoconical zone, a cylindrical zone and a divergent frustoconical zone with a height and a maximum diameter greater than those of the convergent zone. The equipment also includes a combustion chamber (4), a flame ignition system (5), a combustion gas cooling (6) and discharge (7, 8) system and safety devices (9, 10). An Independent claim is also included for the use of the above equipment in a hydrogen bromide manufacturing process comprising (a) forming an intimate mixture of hydrogen and an oxidant in an enclosure; (b) igniting a flame at the enclosure outlet; (c) replacing all or part of the oxidant with a prevaporized bromine stream while maintaining a stable flame for complete combustion of bromine in hydrogen; (d) cooling the combustion gases; and (e) recovering a hydrogen bromide gas stream at ≥ 1 bar absolute pressure and at NOTGREATER 125 (preferably 40-125) degrees C.
