    • 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.
    • 提供了从富含HBr水溶液的水中共同生成Br2,含有CaCl 2和Cl 2的浓缩水溶液和在包含NaCl的CaCl 2中稀释的进料盐水的方法。 这样的方法可以包括将富含HBr的水流和进料盐水加入到塔中,用来自Cl 2源的Cl 2氧化塔内的溴化物部分,其至少一部分根据本发明生产以产生Br2,回收 从塔中除去溴化物贫乏的底部物质,这些底物含有HCl,加入一种Ca ++来源于溴化物贫乏的塔底物,以将基本上所有的底部HCl转化为CaCl 2,根据需要从水中除去水 处理的底部产物以产生浓缩的水溶液,从残余氯化物如NaCl中产生Cl 2和苛性碱,并使用Cl2源中由此产生的Cl 2的至少一部分。

    • Ultraviolet light stabilized antimicrobial compositions are formed from (A) and (B). (A) is (I) a solid-state microbiocidal compound having at least one bromine atom in the molecule; (II) an aqueous solution or slurry of (I); (III) is a concentrated aqueous antimicrobial composition having a dissolved active bromine content derived from (i) BrCl or BrCl and Br2 and (ii) overbased alkali metal sulfamate and/or sulfamic acid, alkali metal base, and water, (IV) solids made by dewatering a composition of (III). (B) is a ultraviolet light degradation-inhibiting amount of up to one part by weight of ascorbic acid, dehydroascorbic acid and/or an edible water-soluble salt/ester thereof per part by weight of bromine in the selected antimicrobial composition. Preparation and uses of such compositions are described. Methods of controlling contamination of seafood and seafood products by pathogens are also described.
    • (A)和(B)形成紫外光稳定的抗微生物组合物。 (A)是(I)分子中具有至少一个溴原子的固态杀微生物化合物; (II)(I)的水溶液或浆液; (III)是具有衍生自(i)BrCl或BrCl和Br2的溶解的活性溴含量的浓缩水性抗微生物组合物和(ii)高碱性碱金属氨基磺酸盐和/或氨基磺酸,碱金属碱和水,(IV)固体 通过脱水(III)的组合物制成。 (B)是所选抗微生物组合物中每重量份溴至多1重量份的抗坏血酸,脱氢抗坏血酸和/或其食用水溶性盐/酯的紫外光降解抑制量。 描述了这种组合物的制备和用途。 还描述了通过病原体控制海产品和海产品污染的方法。
