Project Synopsis
Develop a conceptual design of a modular pretreatment system, a new waste tank, and any project/facility interfaces in support of the Department of Energy Hanford Site.
Project Summary
Process Engineering Associates, LLC (PROCESS) was tasked with developing a conceptual design of a modular pretreatment system, a new waste tank, and any project/facility interfaces in support of a critical decision-1 (CD-1) deliverable for the West Area Risk Management (WARM) project at the Department of Energy Hanford Site.
In this process, the waste feed for the process module originates in the Double Shelled Tank (DST) System and is fed to the process modules where Cesium and Strontium isotopes are removed by an ion exchange media. The process modules include a process enclosure with the filtration and ion exchange equipment and an ancillary enclosure supplying service air and caustic flush. After flowing through the ion exchange columns, pretreated waste will be sent to a Storage Tank for transfer to a Load In/Load Out (LILO) station, where it is loaded into transport tankers for shipment to a permitted treatment facility off-site. Spent ion exchange columns are removed from the process enclosures and transported by forklift to reinforced concrete haul path to a storage pad, where they are anchored in position until a final disposal strategy is implemented.
PROCESS Project tasks included:
- Block flow diagrams (BFDs) preparation
- Process flow diagrams (PFDs) preparation
- Material and energy balance preparation
- Hydraulic calculations preparation using Chemstations CHEMCAD process simulation software
- Process hazard analysis (PHA) support
- Inter-discipline support.
