Patent ID: 6922429

Claim:
A basic hydrogen peroxide (BHP) recycling system comprising a chemical oxygen-iodine laser (COIL); a separating apparatus which receives spent BHP from the COIL and separates the spent BHP into a purified alkali hydroxide/H 2 O 2 stream, which is returned to the COIL, and an aqueous alkali chloride recycle stream having residual alkali hydroxide and H 2 O 2 ; a chloralkali cell; a reactor which receives the alkali chloride recycle stream from the separating apparatus, a depleted anolyte stream from the chloralkali cell, a first alkali hydroxide stream from the chloralkali cell, and a first Cl 2 gas stream from the chloralkali cell, and which evolves a treated alkali chloride stream substantially free of alkali hydroxide and H 2 O 2 which is supplied to the chloralkali cell and an oxygen off gas stream; and a peroxide generator which receives a second alkali hydroxide stream from the chloralkali cell and produces a regenerated stream of BHP, which is supplied to the COIL, wherein a second Cl 2 gas stream is supplied from the chloralkali cell to the COIL.
