A method of generating a refined a sugar stream that comprises xylose from a biomass hydrolysis solution, including contacting a biomass hydrolysis solution that includes a population of mixed sugars comprising xylose, an acid, and impurities, with a thermally-phase separable solvent such as a glycol solvent to form an extraction mixture; and separating from said extraction mixture a first stream including the thermally-phase separable solvent, acid, and impurities and a second, refined sugar stream that comprises xylose.

This disclosure relates to techniques and methods to isolate and purify cannabinoids, such as CBDV, CBD, CBC, THCV, THC, CBN, CBG, CBDA, THCA, or CBGA. Evaporation and sonicating techniques are used to isolate and purify cannabinoids, such as CBDV, CBD, CBC, THCV, THC, CBN, CBG, CBDA, THCA, or CBGA. The resulting compounds find further use within the devices and compositions described herein as well as for preparative and analytical methods.

Disclosed is a method for the manufacture of a spray-dried powder consisting essentially of LNT and/or LNnT, the spray-dried powder, its use for the manufacture of nutritional compositions, and nutritional compositions containing the spray-dried powder.

An improved method of lithium recovery from borax dilute solution is provided. In this method, boron in the borax dilute solution is removed from the medium as borax decahydrate and while this removal process is carried out, liquid-liquid extraction with organic sedimentary chemicals or ion exchange resins are not used.

Systems and methods for producing potassium sulfate. Such a method involves providing an industrial waste material that includes at least one metal sulfate or a metal product that has been reacted with sulfuric acid to produce metal sulfates, and then reacting the metal sulfate with potassium carbonate to produce a byproduct that contains potassium sulfate.

The invention relates to a method for producing a cocrystal of at least two compounds by means of instantaneous evaporation or flash evaporation, for example for the production of cocrystals in the fields of energetic materials, pharmaceutical compounds, phytopharmaceutical compounds, ferroelectric materials, non-linear response materials or bioelectronic materials.

A water evaporation system includes an evaporation module configured to evaporate water from a brine; a support module attached to the evaporation module and configured to support the evaporation module above the brine; and an inlet configured to add a crystal growth inhibitor to the brine.

A method of concentrating and/or producing lithium hydroxide in an evaporator entails feeding a stream comprising lithium, hydroxide and carbonate to the evaporator. In the evaporator, the feed is concentrated to form lithium hydroxide and lithium carbonate crystals. Further, the method entails reducing the tendency of lithium carbonate to scale the evaporator by increasing the concentration of lithium carbonate crystals in the evaporator by: (1) clarifying at least a portion of the concentrate in the evaporator to form a clarified solution; and (2) discharging the clarified solution as a clarified solution stream from the evaporator.

There is disclosed a process for the separation of long chain amino acid and long chain dibasic acid, comprising: (1) adding an ammonium salt to the mixture of alkali salts of long chain amino acid and long chain dibasic acid; (2) heating to remove ammonia; and (3) separating long chain amino acid by solid-liquid separation; and (4) acidifying the salt of long chain dibasic acid with an acid to separate long chain dibasic acid.

The present application relates to a method for preparing L-methionine crystals with an improved bulk density. As the L-methionine crystals prepared according to the method for preparing L-methionine crystals of the present application may have a bulk density of up to 800 g/L, the L-methionine crystals are expected to reduce storage and transport costs of L-methionine powder and improve working conditions due to improved fluidity of the powder.
