Abstract: Thermal oxidiser (1) for the oxidation of a feed liquid (W) comprising an elongated retort (3) provided with a combustion gas input lance (5), a feed liquid input lance (7), one or more flow straighteners (11) and an exhaust gas outlet (13) wherein said retort (3) comprises an elongated wall (15) with a first end plate (17) fastened to a first end (19) thereof and a second end plate (21) fastened to the second, opposite end (23) thereof, combustion gas input lance (5) projects substantially horizontally through first end plate (17) into said retort (3) and feed liquid input lance (7) projects downwards though the retort wall into said retort (3).

Abstract: Disclosed is a process and a system for recovery of isotopologues of water from an aqueous liquid stream containing dissolved impurities.

Abstract: A process for light water detritiation which includes the steps of water distillation for tritium stripping and enriching, followed by chemical conversion of tritium enriched water to elemental hydrogen, and finally by one or more thermal diffusion columns for final tritium enrichment. The combination of process steps takes advantage of water distillation large throughput capability at low tritium concentration with the simplicity of thermal diffusion for small throughput final tritium enrichment. The water distillation front-end and the thermal diffusion back end processes are compatible with any intermediate chemical conversion process such as electrolysis or water gas shift reaction to convert tritiated water to elemental hydrogen.
