Engineering/Cost Evaluation of Options for Removal/Disposal of NC (nitrocellulose) Fines
Abstract
An evaluation of the various options for recovering and treating/ disposing of the nitrocellulose (NC) present in the manufacturing wash streams at the Radford Army Ammunition Plant (RAAP) was undertaken by Arthur D. Little, Inc., for the U.S. Army Toxic and Hazardous Materials Agency (USATHAMA). The technologies evaluated included: Sliding bowl centrifugation for preconcentration; Cross-flow microfiltration for final concentration; Solid bowl centrifugation for final concentration; Incineration for disposal of NC sludge; and Alkaline digestion for pretreatment prior to biological treatment for disposal. The evaluation focussed on the economics of the various technologies, but also addressed the performance characteristics and technical risk associated with implementation of the various process options which could be configured from the evaluated technologies. In carrying out the evaluation, a total of ten (10) technology modules were configured and evaluated. The different modules represented variations in the expected performance of these unit operations under extremes in operating conditions. The ten modules were then configured into ten (10) process options. The overall process options were ultimately subjected to an economic assessment and overall evaluation and ranking. Keywords: Wastewater treatment, Pressure filtration, Capital costs, Operating costs.
