Sodium dichromate closed circulation clean production method for preparing sodium chlorate
TL;DR: In this paper, a closed circulation clean production technique in a sodium chlorate production process is proposed in the method, and the clean SA production without chromium slag emission is realized by using the method.
Patent
Sodium chlorate and chlor-alkali joint denitration process
TL;DR: In this article, a simple and low-cost joint denitration process is described, which has the characteristics of simple process, low cost, circular economy, no introducing of new chemical impurities, effective removing of impurities of the sodium chlorate mother liquor and high additional value.
Patent
Continuous salt production method and system
TL;DR: In this article, a continuous salt production method and system is described for water treatment, which consists of: (1) performing nanofiltration separation to salt-containing water to obtain nano-filtered product water, and (2) performing heat transfer between the nanofiltered concentrated water and low-temperature crystallization product water obtained from the step (4) to obtain cooled nano- filtered concentrated water, where the content X% of divalent anion salt in raw water is less than 5wt%, allowing R1

Nanofiltration of concentrated aqueous salt solutions
TL;DR: Nanofiltration processes using one or more conventional nanofiltration membrane modules under a positive applied pressure is used to selectively change the concentration of one solute, such as sodium chloride or sodium chlorate providing monovalent ions, from another solute such as Sodium sulfate or sodium dichromate to provide multivalent ions in high salt aqueous concentrations.
Patent
Ion exchange removal of dichromates from electrolytically produced alkali metal chlorate-chloride solutions
TL;DR: In this paper, the Ion exchange system is used to remove Dicheroes from an EFFLUENT stream of a kalalkali metal chloride solution by passing the stream through an ion exchange system.
