A plant for preparing a purified isomeric methylene diphenyl diisocyanate monomer from a mixture of different isomeric monomers is disclosed herein. The plant can comprise a distillation apparatus, which comprises: a) a distillation column including a structured packing, b) a source for a mixture of different isomeric methylene diphenyl diisocyanate monomers, c) an evaporator, d) an overhead vapor condenser, e) optionally, an overhead vacuum system and f) a flow-controlled reflux system. The overhead vapor condenser comprises a shell and tube arrangement and is embodied so as to directly subcool the condensate to less than 47° C. The flow-controlled reflux system comprises a heater, which is embodied so as to reheat a partial stream of the condensate formed in the overhead vapor condenser up to 190° C.
SPRAY-DRIED 3-FUCOSYLLACTOSE
Disclosed is a method for the manufacture of a spray-dried powder consisting essentially of 3-fucosyllactose, the spray-dried powder, its use for the manufacture of nutritional compositions, and nutritional compositions containing the spray-dried powder.
Systems and Methods to Recover Value-Added Materials from Gypsum
Disclosed herein are systems and methods from processing flue gas desulfurization (FGD) gypsum feedstock and ash feedstocks, either separately or together. FGD gypsum conversion comprises reacting FGD gypsum (calcium sulfate) feedstock or phosphogypsum, in either batch or continuous mode, with ammonium carbonate reagent to produce commercial products comprising ammonium sulfate and calcium carbonate. A process to separate the impurities and convert the calcium carbonate to a pure precipitated calcium carbonate is disclosed. These impurities include a concentrate of valuable Rare Earth Elements, and radioactive thorium and uranium. A process to convert calcium sulfite to calcium sulfate using oxygen and a catalyst is also disclosed. Ash conversion comprises a leach process followed by a sequential precipitation process to selectively precipitate products at predetermined pHs resulting in metal hydroxides which may be converted to oxides or carbonates. The processes may be controlled by use of one or more processors.
DIAMOND PRESSURE APPARATUS FOR CRYSTALLIZING CANNABINOIDS
An apparatus for purifying diamond CBD oil crystals. A cylindrical glass or metal vessel is provided and supported by least one support post, the vessel having an upper portion and a lower surface having laser etched nucleation sites for initiating crystal growth. A removable head is engageable with the upper portion of the vessel, the head having an uppermost portion and a plurality of ports extending therethrough. A pressurized nitrogen tank is operatively connected to a port of the head, as is a pressure gauge. A safety valve is disposed at the uppermost portion of the head. Optionally, an inline desiccant chamber is also operatively connected to the head. The apparatus crystalizes cannabinoids in either a solventless process or a solvent process.
Recovering a caustic solution via calcium carbonate crystal aggregates
Techniques for growing crystalline calcium carbonate solids such that the crystalline calcium carbonate solids include a volume of 0.0005 mm.sup.3 to 5 mm.sup.3, include a slaker to react quicklime (CaO) and a low carbonate content fluid to yield a slurry of primarily slaked lime (Ca(OH).sub.2); a fluidized-bed reactive crystallizer that encloses a solid bed mass and includes an input for a slurry of primarily slaked lime, an input for an alkaline solution and carbonate, and an output for crystalline calcium carbonate solids that include particles and an alkaline carbonate solution; a dewatering apparatus that includes an input coupled to the crystallizer and an output to discharge a plurality of separate streams that each include a portion of the crystalline calcium carbonate solids and alkaline carbonate solution; and a seed transfer apparatus to deliver seed material into the crystallizer to maintain a consistent mass of seed material.
