    摘要： A process for removing silicon compounds from aqueous NaCl brine includes, first, adjusting a weak brine to a pH value of less than 3 with hydrochloric acid. Iron(III) chloride or other trivalent iron ions are added to the acidified weak brine, the obtained weak brine is then continuously fed to a stirred dissolution vessel which contains undissolved salt in addition to brine. Fresh salt is charged batchwise and intermittently to the dissolution vessel to produce strong brine. The obtained strong brine is fed to a stirred buffer vessel, the pH value in this buffer vessel being maintained at a level ranging from 5 to 8. A strong-brine flow is continuously withdrawn from the buffer vessel and filtered, and the filtrate containing the added iron and silicon is discharged. Also a system for carrying out this process includes: a dissolution vessel for salt, a stirrer in the dissolution vessel, a feed device for batchwise feeding salt to the dissolution vessel, a point for feeding weak brine to the dissolution vessel, points for feeding hydrochloric acid and iron(III) chloride to the weak brine supply line, a buffer vessel for strong brine, a stirrer in the buffer vessel, a flow connection between the dissolution vessel and the buffer vessel, a filter having an outlet for strong brine and a withdrawing device for filter cake, a discharge port and a device for conveying strong brine from the buffer vessel to the filter.

    摘要： The invention provides a method for reducing bromine levels in brine solutions such as potassium chloride brine solutions. Bromide in solution is converted to hypobromite by the addition of an oxidant such as sodium hypochlorite. Hypobromite is precipitated by the addition of a metal cation such as magnesium under conditions of basic pH. The process is pH dependent such that the most efficient removal of bromine is achieved at a sodium hydroxide concentration of 90-200 mM. The pH optimum is also temperature dependent such that increased temperature lowers the optimal pH for bromide removal. The invention further provides a bromine-reduced potassium chloride product, suitable for uses in industrial applications. By the method of the invention bromine levels in a potassium chloride feed stock can be reduced by 97% or more.

    摘要翻译： 本发明提供了一种降低盐水溶液如氯化钾盐水溶液中溴含量的方法。 通过加入氧化剂如次氯酸钠将溶液中的溴化物转化为次溴酸盐。 在碱性pH条件下，通过加入金属阳离子如镁，沉淀出次溴酸盐。 该方法是pH依赖性的，使得在90-200mM的氢氧化钠浓度下实现最有效的溴去除。 pH最佳值也是温度依赖性的，使得升高的温度降低溴化物去除的最佳pH。 本发明还提供一种适用于工业应用的溴还原氯化钾产品。 通过本发明的方法，氯化钾原料中的溴含量可以降低97％以上。

    摘要： The invention relates to an evaporative crystallisation process to make salt compositions which includes a step wherein a mother liquor containing an effective amount of a crystal growth comprising at least one saccharide or saccharide derivative is formed, to form high-purity salt. The salt can be washed with a reduced amount of washing water while still containing lower amounts of K, Br, SO4 and/or Ca. The high-purity salt can be obtained after drying of the salt crystals formed. A wet salt can be obtained by partially drying said salt crystals.
