摘要： 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.

摘要： A method for deep removal of divalent and trivalent scaling ions from heavy oil produced water is described. The method comprises performing divalent and trivalent scaling ion deep removal treatment on heavy oil produced water by using a macroporous weak acid resin, to reduce divalent and trivalent scaling ions in the heavy oil produced water to 50 μg/L. The water quality of produced water treated using the method is superior to the boiler water standard, a silicon removal process in a conventional heavy oil produced water treatment process can be cancelled, and significant economic benefits are achieved.

摘要： A continuous resin regeneration system includes a process by which resin in need of being recharged is continuously recharged and cleaned with a plurality of two-set filtration columns so that resin regeneration and the flow of influent is continuous and interrupted. Downstream filtration columns also undergo this cycling but at slower and related rates as the first column with the dirtiest water will naturally degrade resin faster than the downstream columns. Contaminated influent is cleaned by the continuously recharged resin in multiple column sets. The degree of cleaning of earlier filtration columns affects the resin flow rate of later filtration columns.

摘要： A process for the recovery of a radioisotope from a waste resin of a nuclear power plant comprises the steps of: a) treating a waste resin loaded with at least one radioisotope with an organic acid or alkaline compound to release the at least one radioisotope and to obtain a process solution containing the at least one radioisotope; b) separating the at least one radioisotope from the process solution through a reaction specific to the radioisotope so as to obtain a treated process solution depleted of the at least one radioisotope, wherein said depleted process solution comprises the organic acid or alkaline compound and optionally a non-reacted radioisotope; c) reacting the organic acid or alkaline compound in the depleted process solution from step b) by thermal and/or photochemical oxidation to form gaseous reaction products; and d) reloading the waste resin with the reacted process solution from step c) to bind the non-reacted radioisotope on the waste resin. Further, an apparatus is provided to carry out the above method.
