Where possible, working fluid is recovered and recycled. After drying, if necessary, the propellant may be used in applications less demanding than rocket motors. For example, recovered propellant has successfully been used as a component of explosives for mining and quarrying. This particular reuse application appears to have very promising economic advantages for an integrated system. The converged material and energy balances have been computed and used to generate a tabulation of all of the process stream flows, including waste effluents from those processes that have waste streams.
Some technologies have little or no waste effluent to treat.
Such a comprehensive computerized description of a given technology is expected to be a valuable, user-friendly tool for thorough study of the process parameters that could lead to an optimum design.
