The acid digestion process for treatment of combustible wastes
Description
Acid digestion is a process being developed at the Hanford Engineering Development Laboratory (HEDL) in Richland, Washington, to reduce the volume of alpha-contaminated combustible waste by converting it into a non-combustible residue. Typical waste materials such as polyvinylchloride (PVC), polyethylene, paper and other cellulose materials, ion exchange resin, all types of rubber, etc., are digested in hot (230 deg C-270 deg C) concentrated sulfuric acid containing nitric acid oxidant to form inert residues having less than 4% of their original volume. The process is currently being tested in a non-radioactive Acid Digestion Test Unit (ADTU) using all glass equipment. Engineering tests to date have shown acid digestion to be a potentially attractive method for treating combustible waste materials
