摘要： Salt production can include preparing hydrohalite particles by crystallization from saturated brine, adding the hydrohalite particles to a salt brine, thereby forming a hydrohalite-salt brine mixture, agitating the hydrohalite-salt brine mixture until the hydrohalite particles have decomposed into NaCl crystals, and filtering out the NaCl crystals from the salt brine. In some instances, an initial temperature of the salt brine prior to adding the hydrohalite particles is at least 0° C. In some instances, a ratio of salt brine to hydrohalite particles, by weight, is from 0.4 to 29.

摘要： An evaporation still for producing sea salt having a chamber that contains a bottom, a plurality of sides including a front side, a back side, a first side, and a second side, the front side and the back side being substantially parallel, and the first side and the second size being substantially parallel, and a top. The top contains a centered portion extending from the first side to the second side, the centered portion being substantially parallel to the front side and the back side, a first window extending in a downward slope from the centered portion towards the front side, and a second window extending in a downward slope from the centered portion towards the back side. The evaporation still also contains a plurality of legs. The first window extends from the centered portion beyond the front side such that condensation formed inside of the chamber drains outside of the chamber, and the second window extends from the centered portion beyond the back side such that condensation formed inside of the chamber drains outside of the chamber.

摘要： A method and system for rapidly preparing lithium carbonate or concentrated brine using high-temperature steam. The method comprises the steps of: feeding brine into a reactor, heating the brine with high-temperature steam above 200° C. while simultaneously discharging steam produced in the reactor, cooling and condensing the discharged steam in a condenser and collecting the condensate, and stopping the high-temperature steam after the brine is concentrated to a predetermined concentration or after a sufficient amount of lithium carbonate is collected. The system comprises: a reactor provided with a brine inlet, a steam outlet connected to a condenser, a product outlet, and a plurality of steam pipes. The method concerns the direct heating of brine using high-temperature steam, which is effective and efficient, and also produces fresh water. The heating is uniform and rapid, and does not require jackets, heat exchange tubes, mixers and vacuum pumps, vastly simplifying the system.

摘要： A sodium chloride recovery method for upgrading a mixed salt stream from lower sodium chloride purity to an increased sodium chloride purity is provided. The salt recovery method utilizes the solubility properties of the impurities in the mixed salt to preferentially dissolve them over sodium chloride. As the impurities are removed from the solid phase using a salt stripper, sodium chloride rich slurry is generated. The rich salt slurry is processed by an upgrader to remove the remaining impurities. The upgraded sodium chloride slurry is dewatered and washed in the phase separator to generate sodium chloride salt at a higher purity.

摘要： A method of producing potassium sulfate by employing sodium sulfate and potassium chloride sources is disclosed. The method includes a crystallization process that yields a mother liquor containing sulfate, sodium and chloride. The mother liquor is directed to an anion segregation unit that produces a reject or retentate rich in sulfate which is recycled and employed in the production of the potassium sulfate. Further, the anion segregation unit produces a permeate that is depleted in sulfate but includes sodium and chloride and is directed to a sodium chloride crystallizer for producing sodium chloride.

摘要： A process for treating wastewater or waste brines that include sodium and chloride ions. The waste brine is concentrated and thereafter directed to a Mirabilite crystallizer that produces hydrated sulfate salt crystals and a first solution. The hydrated crystals are melted to form an aqueous sulfate solution that is directed to a sodium sulfate crystallizer which produces sodium sulfate salt crystals. The first solution produced by the Mirabilite crystallizer is directed to a nanofiltration device which produces a permeate stream and a reject stream containing sulfate removed by the nanofiltration device. The permeate stream is directed to a sodium chloride crystallizer that produces sodium chloride salt crystals. The reject stream is recycled to the Mirabilite crystallizer.
