SYSTEM AND METHOD FOR ON-SITE CLEANING AND RESTORATION OF KINETIC PROPERTIES OF ION EXCHANGE RESIN
20240165603 · 2024-05-23 ·

A system and method for on-site cleaning of an ion exchange resin is disclosed. The system includes a mixing tank in fluid communication with a resin vessel, first and second chemical sources, first, second, and third pumps, and a deionized water source. The mixing tank and pumps are mounted on a portable skid. A cleaning solution is made within the mixing tank by displacing oxygen from the tank with a nitrogen blanket, and injecting a sulfite solution, an acid, and deionized water into the mixing tank. The third pump is configured to recirculate and mix the cleaning solution, drawing the cleaning solution from the mixing tank, past an instrument bank, and back into the mixing tank until mixed. The third pump is also configured to inject the cleaning solution into the resin vessel containing the ion exchange resin. The portable system is in fluid communication with a waste sump.

Processes and systems for producing and/or purifying gallium-68

The present disclosure relates processes and systems for producing and/or purifying .sup.68Ga from an irradiated substrate of .sup.68Zn. In some embodiments, the process rely on the use two cation-exchange chromatography columns to separate .sup.68Ga from .sup.68Zn and other radionuclides and metallic impurities. The process achieves a high overall yield of .sup.68Ga and a high effective molar activity while being implementable in a time compatible with the short half-life of .sup.68Ga. In additional embodiments, the process is implemented by an automated system.

SYSTEM AND METHOD FOR REGENERATING AND RESTORING KINETIC PROPERTIES OF RESIN
20240189808 · 2024-06-13 ·

A system and method configured to restore ion exchange kinetic properties and purify resin is described. Degraded ion exchange kinetic properties of anion resin will eventually result in impurity slippage through resin charges. This system and method employs an acid catalyst in combination with sulfite cleaning solution to remove organic material and to protonate iron oxides for deconstruction and removal from anion resins. The cleaning solution, when applied via a cleaning vessel utilizing an eductor(s)/plenum and wedge-wire screen draw chamber, while controlling all phases of cleaning by electronic monitoring, yields complete restoration of ion exchange kinetics on usable resin. As such, the system and method provides a safe, effective, and vastly improved method for restoring anion resin kinetics and improving regeneration quality, for improved resin performance and minimizing resin replacement costs.
