As part of a process that is being developed to vitrify tailings from Belgian Congo ore that is stored in large silos at a former U.S. Department of Energy uranium-processing facility in southwestern Ohio, process off-gas is produced that contains large concentrations of radon gas (on the order of hundreds of thousands of picocuries per litre). To meet U.S. Environmental Protection Agency restrictions, the process off-gas must be stripped of its radon content before it is vented to the atmosphere. It is appropriate to consider a charcoal bed as part of an off-gas treatment system for the removal of radon at the vitrification facility. However, a difficulty arises in incorporating a charcoal bed into an off-gas treatment system at a vitrification facility. That difficulty is that the capability of the charcoal bed to capture and retain radon gas decreases with increasing bed temperature. Thus, it may be necessary to include a water scrubber in the off-gas treatment system to cool the process off-gas before it is passed through the charcoal bed.
