An alternative to open burning treatment of solid propellant manufacturing wastes

Chemical Systems has selected base hydrolysis treatment to replace open burning of solid propellant manufacturing wastes. This treatment approach was adapted from several technologies. Reclaim/reuse and experimental treatment technologies were combined into the selected treatment process. Adoption of this change in treatment technology requires characterization and minimization of waste streams and alternate product development. The treatment facility design and permitting are discussed. Experiments performed on three representative types of solid propellants demonstrate the process feasibility and characterize the products of the hydrolysis. The products of the propellant treatment are ammonia, hydrogen, nitrogen oxide gasses, soluble inorganic and organic salts, and insoluble polymeric and metallic materials. Materials contaminated with propellant are cleaned and separated from the hydrolysate. The products of the process will be treatable in conventional waste treatment facilities
