Abstract
An ion exchange system includes one or more strategies to reduce the amount of hydrogen gas inside an ion exchange column when the column is offline or disposed of. The ion exchange system comprises an ion exchange column including a housing and ion exchange media positioned in the housing. The ion exchange column can include one or more of the following: (1) an oxide material that limits the production of hydrogen gas from radiolysis, (2) a hydrogen scavenging material that removes or scavenges hydrogen gas inside the column, and (3) a hydrogen catalytic material that catalyzes the reaction of hydrogen and oxygen inside the column.
Claims19
An ion exchange system comprising:
- an ion exchange column including a housing and ion exchange media positioned inside the housing;
- an enclosure positioned inside the housing;
- and
- a hydrogen scavenging material positioned inside the enclosure, the hydrogen scavenging material being capable of removing hydrogen gas from the inside of the housing;
- wherein the enclosure includes a sealing device moveable between a closed position where the hydrogen scavenging material is not in fluid communication with the ion exchange media and an open position where the hydrogen scavenging material is in fluid communication with the ion exchange media.
An ion exchange system comprising:
- an ion exchange column including a housing and ion exchange media positioned inside the housing;
- an enclosure positioned inside the housing;
- and
- a hydrogen catalytic material positioned inside the enclosure, the hydrogen catalytic material being capable of catalyzing the reaction of hydrogen and oxygen and reducing the amount of hydrogen gas inside the housing;
- wherein the enclosure includes a sealing device moveable between a closed position where the hydrogen catalytic material is not in fluid communication with the ion exchange media and an open position where the hydrogen catalytic material is in fluid communication with the ion exchange media.
An ion exchange system comprising:
- an ion exchange column including a housing and ion exchange media positioned inside the housing;
- and
- an oxide material positioned inside the housing, the oxide material having a G-value for hydrogen from beta and gamma radiolysis that is no more than 0.45;
- wherein the oxide material is mixed with the ion exchange media.
