Nitrate destruction by a plasma torch
This report presents the results of a test program which investigated the feasibility of a plasma-based system to process metal nitrate wastes by transforming them into the corresponding metal oxides and separating these oxides from the gas stream. The test program included performing a thermodynamic study of the proposed process, design and preparation of the actual test program, performance of that test, analyzing the results of the test, and documenting the results of the program in this report. The test was performed for the Westinghouse Materials Company of Ohio (WMCO) by the Westinghouse Environmental Technology Division (now the Environmental Services Division). All testing was completed at the Plasma Center located at the Westinghouse Waltz Mill Site, Madison, Pennsylvania. The primary objective of this proof-of-principle experiment was to demonstrate that raffinate solutions containing nitric acid and various metal nitrates, when treated in a plasma torch reactor, would decompose the nitrates to oxides and that the product solid metal oxides could be separated from the gaseous product nitrogen oxides. 15 figs., 10 tabs.
