Cleanup and recovery of high TOC (Total Organic Carbon) D2O at Pickering NGS

A process was developed in-house using readily available components from local vendors, pumps and storage tanks no longer used by the station. This process proved successful in bringing the total organic carbon (TOC) content of the D2O to an average of 3 ppm, which was then fed through the ion exchange cleanup system (IXCU) for final polishing and sent to the station upgrader as feed. It is estimated that this process has saved the station several million dollars in processing costs alone, based on an estimate from a contract company to clean up a small volume of the TOC contaminated D2O. The estimated value of the recovered D2O is approximately $54 million. (author)
