In an embodiment, a method of recovering acetone comprises separating a bisphenol A stream into a bisphenol A product stream and an extraction stream comprising unreacted acetone; recovering the unreacted acetone in a recovery section of the bisphenol A production facility and forming a bisphenol A plant acetone recovery stream comprising methanol and a recovered acetone; introducing the bisphenol A plant acetone recovery stream to a phenol purification plant; and purifying the bisphenol A plant acetone recovery stream in the phenol purification plant to form an acetone product stream. The acetone product stream can comprise a reduced amount of methanol as compared to the bisphenol A plant acetone recovery stream.

An apparatus for separating a mixture of two liquids of different densities which liquids are substantially insoluble in one another includes a hollow permeable body having a recess for receiving a first fluid which can flow from the recess through the permeable body to an exterior of the permeable body. A housing surrounds and is spaced from the exterior of the permeable body. The housing has an inlet for a second fluid and an outlet for a mixture of the first and second fluid. A baffle or baffles are provided in the space between the exterior of the permeable body and the housing, and to define a mixing channel in space between the exterior of the permeable body and the housing so that the second fluid can enter the housing inlet and flow through the mixing channel to the outlet, while picking up fluid on the exterior of the permeable body.

An arrangement (100) for production of fully soluble, pure and well defined mono- or di-ammonium phosphates, comprises an extraction section (10), a stripping section (20) and end treatment arrangements (90). The extraction section performs a liquid-liquid extraction of phosphate between a feed liquid (1) comprising phosphoric acid and being essentially free from nitrate ions, and a solvent (5) having a solubility in water of less than 2%. The stripping section performs a liquid-liquid extraction of phosphate between solvent loaded with phosphate and a strip solution (4). The solvent depleted in phosphate is recirculated to the extraction section for further extraction of phosphate. The strip solution is an aqueous ammonium phosphate solution, wherein at least 80% of the ammonium phosphate is monoammonium phosphate and/or wherein the solvent is a water-immiscible alcohol. The end treatment arrangements comprise a source of ammonia (60), an adding arrangement (70), a cooling arrangement (50), a precipitate remover (40) and a recirculation system (80).

The mixing system for ready-to-use flush solutions is characterized by an RO system, a mixing unit that is connected to the RO system and that contains a mixing chamber, to which high-purity water can be fed from the RO system and flush solution concentrate can be fed from a concentrate source, and a flush solution link connector, wherein the RO system and the mixing unit form a filling station, a mobile flush solution container that contains a pressurized container that receives a flush solution bag that can be coupled to the flush solution link connector of the mixing unit, and a computer and control mechanism for all measurement and monitoring tasks during the local production of a flush solution, wherein the mobile flush solution container and the filling station are provided with sensors by means of which wireless communication is made possible between the mobile flush solution container and the filling station.

Targetry coupled separation refers to enhancing the production of a predetermined radiation product through the selection of a target (including selection of the target material and the material's physical structure) and separation chemistry in order to optimize the recovery of the predetermined radiation product. This disclosure describes systems and methods for creating (through irradiation) and removing one or more desired radioisotopes from a target and further describes systems and methods that allow the same target to undergo multiple irradiations and separation operations without damage to the target. In contrast with the prior art that requires complete dissolution or destruction of a target before recovery of any irradiation products, the repeated reuse of the same physical target allowed by targetry coupled separation represents a significant increase in efficiency and decrease in cost over the prior art.

Sample purification systems include a particle extraction assembly having a mixing compartment and a settling compartment. A biological sample is mixed with two liquid phases formulated to effectuate transfer of a biological molecule into a first phase and particulate contaminants into a second phase. The first phase includes a solubilizing salt, the second phase includes an organic molecule, and the mixture can have little or no monoatomic salt or dextran. The molecule-containing first phase can be optionally concentrated without also concentrating the particulate contaminants and introduced into a multi-stage liquid-liquid extractor, by which the biological molecule or molecular contaminants are extracted from the first phase into a third phase, thereby purifying the molecule away from contaminants. The extracted sample can be further purified through a series of processing steps. The system can be run in continuously mode to maintain sterility of the sample.

A method of recovering organic components from an aqueous biomass in the method includes: (i) providing an aqueous biomass containing organic components; (ii) treatment of the aqueous biomass to release intracellular organic components from within cells of the biomass to form a biomass suspension; addition of a water-immiscible component to the biomass suspension to form a mixture comprising biomass and water-immiscible component; (iv) subjecting the mixture comprising biomass and water-immiscible component to high shear to form a water-in-water-immiscible-component emulsion; and (v) separating the water-immiscible component phase from the water/aqueous phase.
