A process for the management of by-product tetranitromethane (TNM) which avoids the hazards of the prior art isolation or extraction procedures. A selected in-plant liquid or vapor stream, or a reactor off-gas stream from nitration or nitric acid oxidation plant, which contains TNM, is heated to effectively pyrolyze the TNM without undue losses of nitric acid values.

Process for the destruction of by-product tetranitromethane

A process and apparatus is provided for the continuous manufacture of a water-in-oil explosive emulsion precursor. Separate streams of the water phase component and the oil phase component are introduced into an in-line motionless mixer. A chosen portion of the output from the mixer is recirculated and returned to the motionless mixer for further emulsification. The process allows for the production of a very high phase ratio water-to-oil emulsion (up to 95% water phase) without phase inversion after long storage. The precursor is simply converted to a sensitive explosive by means of known density lowering techniques.
