    Abstract: This invention is a combination process for producing elemental bromine using a seawater feed. The process involves a series of steps in which seawater is acidified, chlorinated, and air stripped to remove the bromine. The stripping effluent is reacted with an SO2 stream to convert the bromine to hydrogen bromine and H2SO4 in the air stream. The process continues by absorbing hydrogen bromide and H2SO4 from the resulting acidic fog to produce an aqueous H2SO4 stream containing HBr. The HBr is stripped from the liquid stream and passed to an oxidation reactor where it is catalytically oxidized with an oxygen-containing gas to produce a stream of Br2 and H2O. The hot reactor effluent is quenched and the product Br2 is separated from the H2O and inert gases such as air. In the figure 2 seawater enters pipeline (202) and is mixed with an H2SO4 stream (200). The resulting stream (214) is sent to a stripping column (218) where air stream (216) strips the bromine from the liquid. The vapor B22 stream (222) is mixed with SO2 (224) which is contacted with a water stream. The resulting aqueous H2SO4/HBr stream (236) is heated and mixed with a chlorine stream (240). A portion of the chlorine is introduced through line (241) to the bottom of stripping column (242) and separates with stream (244) into stream (246) containing H2O4 and HCl separates with stream (244) into stream (246) containing H2SO4 and HCl and stream (248) containing Br2. The Br2 product (260) is discharged from decanter (254) into the purification unit (255).

    Abstract: This invention is a combination process for producing elemental bromine using bromide salt feedstocks. The process involves acidifying an inorganic bromide salt with a strong and concentrated acid, preferably sulfuric acid, to produce a gaseous HBr stream. The HBr stream is then mixed with an O2-containing gas and passed to an oxidation reactor where it is catalytically oxidized to produce a stream of Br2 and H2O. The hot reactor effluent is quenched and the product Br2 is separated from the H2O. In the figure, HBr stream is introduced into an evaporator (204) and to superheater (206). The O2 feedstream (208) is warmed. A reactor feedstream (214) is introduced into (216). The reaction product stream (218) is cooled in stages (220) and (222) and condensed. The condensate is then separated into a Br2 stream (224) added to water stream giving stream (226) and (228). The device (230) is a separator and (232) is a refrigeration unit. The resulting stream (234) is mixed with Br2 stream (224) giving noncondensed oxygen vapor stream (236) which is scrubbed in a gas treater (238). Distillation column (242) produces two streams (252) and (244). The overhead vapor stream (244) is condensed in overhead condenser (246) and collected in drum (248). The stream (250) is mixed with other streams. Device (256) is an absorption tower and (258) is the Br2 product stream.

    Abstract: This invention is a combination process for removal of sulfur oxides (SOx) from gases containing both the SOx and oxygen (106). The fluid used to remove the SOx contains sulfuric acid and bromine. The SOx is converted to sulfuric acid and the bromine is thereafter converted to hydrobromic acid. The hydrobromic acid is concentrated and catalytically converted to bromine for ultimate recycling to the SOx removal step (132). The SOx is finally recovered as a strong sulfuric acid (104).

    Abstract: This invention is a catalyst and a process using that catalyst for oxidizing hydrogen bromide to form elemental bromide. The inventive catalyst comprises a composition of promoted or stabilized copper bromide on a zirconium-containing support. In the figure, an HBr stream (202) is sent to an evaporator (204) and to a super heater (206). The O2 feed stream (208) is warmed with heater (210). The O2 and HBr mixed reactor feed stream (214) is introduced into reactor (216). The reactor stream (218) may be cooled in two stages (220) and (222) and also condensed. The device (230) separates condensed liquid into (224), (226) and (228) streams. The vapor stream (228) is chilled in refrigeration unit (232) to remove Br2. A resulting Br2 stream (234) is mixed with stream (224). A non-condensed O2 vapor stream (236) is scrubbed in a gas treater (238). The treated O2 is vented (240) or may be recycled to reactor (216). The aqueous stream (226) coming from the separator (230) is then stripped of Br2 in a distillation column (242) and produces two streams (244) and (250), where (240) is condensed in condenser (246) and collected in drum (248). The stream (250) is mixed with other Br2 streams (224) and (234) for further treatment in counter-current absorption tower (256) producing a Br2 product stream (258).
