  • Patent number: 10648061
    Abstract: Producing high purity lithium solution from a lithium source containing dissolved Na+, Ca2+, and Mg2+, by: passing the source into and out of a bed of sorbent composed of hydrated alumina intercalated with LiX, preferably LiCl, to extract lithium from the lithium source into the sorbent; washing the bed of sorbent with dilute aqueous LiCl to remove lithium from the sorbent to obtain a lithium eluent of increased Li+ concentration; subjecting this eluent to nanofiltration to produce a lithium permeate from which Ca2+, Mg2+, and other nanofilterable components are concurrently removed, yielding a permeate solution with 25% or less, and a retentate solution with 75% or more Ca2+ and Mg2+, as compared to the eluent from washing; and subjecting the permeate solution to a particular forward osmosis yielding a solution having 13,000-25,000 ppm dissolved lithium. Specified optional steps and new features can be used to increase lithium concentrations and purity.

  • Patent number: 9485998
    Abstract: Poultry carcasses are contacted with water treated with one or more specified dihalodialkylhydantoin biocides in a processing operation downstream from a scalding tank. The aqueous effluent from that downstream operation or from any location further downstream is recycled to the scalding tank. Surprisingly, the bromine residues from the dihalodialkylhydantoin biocides are much more thermally unstable than, for example, the commonly used microbiocide, sodium hypochlorite. Thus, the effluent from the scalding tank has its active bromine content significantly reduced before it is sent to a water purification facility wherein microbial action is used to reduce the BOD of the waste water before its release to the environment. Thus, injury to this desired microbial action is reduced. In addition, the recycle reduces water consumption in the overall poultry processing operation.

    Abstract: Processes of and systems for removing free bromine from gaseous anhydrous HBr contaminated with free bromine are described. In one type of process the gaseous contaminated HBr is fed into countercurrent contact with at least one liquid alkylaromatic hydrocarbon within a packed section of a column while maintaining the packed section under free radical bromination conditions so that one or more than one liquid a-bromoalkylaromatic compound is produced along with one mole of gaseous HBr per mole of a-bromoalkylaromatic compound produced. In another type of process the gaseous anhydrous HBr is fed into countercurrent contact through at least two scrubbers so that the gaseous anhydrous HBr is scrubbed substantially free of bromine by passage through these at least two scrubbers, each of which contains a different specified type of scrubbing liquid. In one embodiment the liquid alkylaromatic hydrocarbon comprises 1,2-diphenylethane.
