摘要： The invention discloses a purification method, system and a detection method of N-methylmorpholine N-oxide (NMMO), and a N-methylmorpholine N-oxide obtained thereof. The NMMO is derived from a NMMO crude product prepared by the reaction of N-methylmorpholine with hydrogen peroxide. The mass concentration of NMMO in the NMMO crude product is 50% to 60%. The purification method includes: performing cooling crystallization to the NMMO crude product between −20° C. and 78° C. to obtain crystalline NMMO. The NMMO purification method has a low cost, a high purity of the obtained NMMO product, and almost no generation of exhaust gas, waste water, and solid waste. Different from current NMMO purification process, the purification method of the invention does not require ion-exchange resin, thus completely solved problems of significant amount of wastewater with high concentration of salt and COD and spent ion-exchange resin caused by the regeneration of ion-exchange resin.

摘要： A water treatment process (10) includes, in a crystallisation stage (12), passing a saline water feed (16) through an elongate conduit kept in a cold environment at a temperature below the equilibrium freezing temperature of the saline water, forming a slurry of brine and ice crystals inside the conduit, and, in a separation stage (14), separating the ice crystals from a bulk of the brine, producing a brine stream (22) and an ice stream (26). The elongate conduit is of a material, or has an inner material layer in contact with the saline water and with the slurry of brine and ice crystals, with a thermal conductivity of less than 5 W/m·K and has a length configured to ensure formation of the slurry of brine and ice crystals in the conduit at the flow rate of the saline water feed through the elongate conduit.

摘要： The present disclosure provides a system for refining long chain dicarboxylic acid, comprising: a first membrane filtration unit, for a first membrane filtration of a long chain dicarboxylic acid fermentation broth or a treated liquid therefrom; a first decolorization unit, for carrying out a first decolorization treatment to the filtrate obtained after the membrane filtration; a first acidification/crystallization unit, for carrying out a first acidification/crystallization of a filtrate obtained after the membrane filtration to give a solid-liquid mixture; a first separation unit, for a solid-liquid separation of the solid-liquid mixture; a drying unit, for drying the solid separated by the separation unit to give a first solid. By using the refining system according to the present disclosure, the purity of the obtained product is high, and the disadvantages such as poor quality of the product obtained by crystallization from a solvent and environment pollution caused by a solvent can be overcome.

摘要： A gas injection module for separating minerals is disclosed. The gas injection module injects a gas to a supersaturated solution containing at least one mineral. The gas injection causes at least a portion of the supersaturated solution to crystallize. The supersaturated solution can be created using a clay, such as a raw Zeolite clay and a liquid (e.g., water). The Zeolite clay can contain lithium and be crushed before it is mixed with the liquid. A non-crystallizing portion of the supersaturated solution can be recirculated within the gas injection module for additional exposure to the gas and/or be processed by a reverse osmosis system.

摘要： This disclosure provides systems and methods for direct production of lithium hydroxide by utilizing cation selective, monovalent selective, or preferably lithium selective membranes. Lithium selective membranes possess high lithium selectivity over multivalent and other monovalent ions and thus prevent magnesium precipitation during electrodialysis (ED) and also address the presence of sodium in most naturally occurring brine or mineral based lithium production processes.

摘要： Provided are a continuous post-treatment method and device for a penem compound. The method includes the following steps: S1, performing continuous extraction on a reaction crude product of a penem compound, to obtain an extraction heavy phase and an extraction light phase; S2, performing continuous solid-liquid separation on the extraction heavy phase, to obtain a liquid phase separation product; S3, performing continuous pH adjustment on the liquid phase separation product until a pH value thereof is 6.1-6.3, to obtain pH-adjusted solution; and S4, performing continuous crystallization treatment on the pH-adjusted solution by a first crystallization solvent, to obtain a penem compound product. The use of the method for the post-treatment of the reaction crude product of the penem compound has the advantages of high treatment speed and high efficiency, and stable material properties and a low deterioration rate during the treatment, and has better control over the yield and purity of a target product.
