were due to the low concentration of dissolved organic and NOx generating
inorganic components (such as nitrate/nitrite) in the solution.
In one case (PBXN-109) the emissions of carbon monoxide was quite high
(2777 ppm). This material was hydrolyzed using 20 to 50% DMSO to swell
the binder. This was necessary since the binder used in PBXN-109 is not
hydrolyzed by sodium hydroxide and a limited reaction occurred in aqueous
solutions. The resulting hydrolysate contained substantial quantities of
DMSO, which does not burn cleanly at the operating temperature used to
destroy explosives (7500C). The amounts of carbon monoxide could be
reduced by .operating the molten salt unit at higher temperatures (e.g.
900*C).
These experiments processed base hydrolysate at 1.4 gallons per hour, and
the time required to process the liquid from all four explosives required 3.5
hours. This was insufficient time to reach steady state. The feed material
was not completely characterized, so any conclusions drawn from these
experiments must be considered as preliminary. However, 14 liters of
material was processed is a short amount of time without incident. With
one exception (noted above) the gaseous emissions from the molten salt
destruction of base hydrolysate were low. We are, therefore, hopeful that
molten salt destruction is an ideal method to process waste from a large-
scale base hydrolysis program.
