Abstract:
Die Erfindung betrifft ein Verfahren zum zumindest teilweisen Trennen von mindestens zwei Stoffen eines Gemisches, insbesondere zum Konzentrieren oder Reinigen bzw. Veredeln des Gemisches, wobei jeder der Stoffe einen unterschiedlichen Siede- bzw. Verdampfungspunkt und Schmelz- bzw. Verfestigungspunkt aufweist, umfassend die Schritte: Temperieren und/oder Druckverändern des Gemisches, sodass sich der Aggregatzustand eines der Stoffe von dem Aggregatzustand mindestens des anderen Stoffes unterscheidet, wobei das Temperieren und/oder Druckverändern weiter die Schritte umfasst: Einfüllen des Gemisches in ein Gehäuse, Temperieren des Gemisches mittels Kontaktieren einer in dem Gehäuse angeordneten Wärmetauschereinrichtung unter Rühren des Gemisches, wobei beim Rühren das Gemisch entlang der Wärmetauscheroberflächen nach außen bewegt wird und wobei eine Kraftübertragung für das Rühren von außerhalb des Gehäuses nach innen kontaktlos ohne Durchbruch durch das Gehäuse durchgeführt wird. Darüber hinaus betrifft die Erfindung eine Vorrichtung, ein Konzentrat und eine Verwendung hierzu.

Abstract:
A process is described for recovering alkali-chloride and alkali-sulfate salts from a salt solution. The salt solution comprises alkali metal, chloride and sulfate ions and is directed to a hydrous salt crystallization unit (28) which crystallizes hydrated sulfate salts that comprise sulfate and at least one alkali metal. A purged solution from the hydrous salt crystallization unit (28) is directed to a chloride salt crystallization unit (38) while the hydrated sulfate salt crystals are melted to form an aqueous sulfate solution which is directed to a sulfate crystallization unit (32). Anhydrous sulfate salts are crystallized from the aqueous sulfate solution to form sulfate salt crystals comprising sulfate and at least one alkali metal. In the chloride salt crystallization unit (38), chloride salt is crystallized to form chloride salt crystals. At least a portion of the purges from the sulfate and chloride salt crystallization units (32, 38) is directed to the hydrous salt crystallization unit (28).
Abstract:
Set forth herein is a new method of salts cleaning from higher solubilization impurities by virtue of homogenization thereof with a solvent until the obtainment of a uniform suspension and curing thereof at a constant temperature, whereby the solubility factors delta for he salts subject to separation is the highest, the salt thus cleaned being then filtered and separated from the contaminated mother solution, the latter to be recirculated to the initial point of the process for further extraction of all the remaining components of the mix.
Abstract:
A method of crystallization is provided. The method includes providing a solution comprising a solute dissolved in a first solvent. The method includes providing a dispersion comprising a plurality of nanoparticles in a second solvent. The first solvent and the second solvent are mutually miscible. The method includes combining the solution and the dispersion to form a mixture. The nanoparticles remain dispersed in the mixture and the solute remains dissolved in the mixture at or below a saturation concentration. The method includes cooling the mixture such that the solute exceeds the saturation concentration forming crystals in the presence of the dispersed nanoparticles. The method includes separating the crystals from the mixture, wherein the nanoparticles remain dispersed in the mixture.
