MULTI-DIMENSIONAL LIGAND-ASSISTED CHROMATOGRAPHY METHOD FOR THE PURIFICATION OF RARE EARTH ELEMENTS AND OTHER METAL IONS FROM WASTE MAGNETS
20230093246 · 2023-03-23 ·

A method of recovering substantially rare earth elements (REEs) from magnets, including first dissolving a magnet to yield a solution containing Nd, Pr, and Dy, and then equilibrating a first column with Cu2+ solution to yield a first equilibrated column, introducing the solution to the first equilibrated column, and introducing a ligand solution to the first equilibrated column to establish three bands of different liquid compositions in the column, wherein the three bands comprise a Dy/Nd mixed band, a first pure Nd band, and a Nd/Pr mixed band. Next, sending the Dy/Nd mixed band to a second column containing a Cu2+ solution and introducing a ligand solution to the second column to establish a pure Dy band and a second pure Nd band in the second column, and sending the Nd/Pr mixed band to a third column containing a Cu2+ solution and introducing a ligand solution to the third column to establish a third pure Nd band and a pure Pr band in the third column. Finally, eluting the respective pure Nd bands to recover Nd, eluting the pure Dy band to recover Dy, and eluting the pure Pr band to recover Pr.

11607624 · 2023-03-21 · ·

A method for purifying a nonaqueous liquid substance includes: filling a cartridge container with a macroporous or porous type ion exchange resin in a water-wet state to obtain an ion exchange resin-filled cartridge filled with the macroporous or porous type ion exchange resin before water content reduction; reducing a water content of the macroporous or porous type ion exchange resin in the cartridge container until a water content (A) of the macroporous or porous type ion exchange resin after water content reduction becomes 90 to 97% of a water content (B) of the macroporous or porous type ion exchange resin in a saturated equilibrium state; an initial blowing step of allowing the nonaqueous liquid substance before being purified to pass inside the cartridge container filled with the macroporous or porous type ion exchange resin after water content reduction and discharging an initial blow effluent from inside the cartridge container; and purification.

Method for purifying and recovering solvent from ion exchange processes

The invention relates to a system and method of use for concentrating a solution that is eluted from an ion exchange process (elution solution) during an ion exchange regeneration using the osmotic pressure of the salt saturator. This method recovers solvent from the elution solution that could be used in a future ion exchange regeneration process. The concentration of the elution solution may include the precipitation and removal of solids from the elution solution.

METHODS FOR THE PURIFICATION OF PROTEINS USING CAPRYLIC ACID
20220324906 · 2022-10-13 ·

A protein purification process with virus inactivation or removal uses caprylic acid (octanoic acid) at acidic pH. The method comprises caprylic acid treatment as part of the chromatographic step so as to perform viral inactivation without a discontinuous process and without the requirement of attention by personnel, particularly when the pH adjustment of the eluate is performed automatically by eluting into buffer. The method of the invention further results in mycoplasmas being inactivated, and reduced impurities like Host Cell Protein (HCP).
