Technique and installation for deuterium-depleted water production

Abstract

Deuterium-depleted water (DDW) production technique consists in separating the deuterium from water through a continuos distillation process under pressure of about 133.3 mbar. Water that is use as basic material has an isotopic content of 144 ppm D/(D+H) and can be demineralized water, distillate water or condensed-steam. DDW result as distillate with an isotopic deuterium content of 15-80 ppm, depending on the level we went to achieve. The process take place in a installation consisting of one or two distillation column filled with structured packing which was treated improve their wetting properties by special chemical procedure. The feeding is make at the bottom of the column, the installation functioning as depleting section referring at deuterium. The quality of DDW, excepting the deuterium content, is similar to distillated water quality. Romania has possibility to produce 2.000 tones of DDW/year. To test the deuterium content of DDW is use the mass spectrometry method. DDW is use in making isotope standard and in the future it is the perspective to use it as bioactive product in medicinal purposes, in pharmaceutical industry, agriculture and animal breeding.
