Effluent Treatment Facility (ETF) Acetonitrile Steam Stripper
Project Highlights
- Detailed alternative analysis.
Project Description
The ETF treats secondary liquid waste generated from radioactive waste streams on the DOE Hanford site. Anticipation of acetonitrile concentration above the delisting requirements within the effluent stream from the waste treatment plant (WTP) resulted in a need to provide additional waste processing capabilities. The existing ETF systems do not support removal of acetonitrile from effluent streams. Supplemental treatment is needed to support treatment of the future effluent stream of the Hanford tank waste treatment and immobilization effluent management facility (EMF).
Project Scope
An evaluation of the new waste profile identified a concentration of acetonitrile within the WTP EMF waste stream exceeding the delisting treatability envelope limit.
Prior to initiating work on the 30% design activities, the project team went through a detailed, systematic alternative analysis phase to better define the scope and optimize the process. A report was developed and design activities were then initiated.
In addition to the detailed design which resulted in design media used to implement the project, Sargent & Lundy provided engineering support during construction activities.
- Detailed drawings.
- Calculations, specifications, assessments, reports, and matrices.
- Construction support documents, engineering change notices.
