摘要： Deuterium-depleted water is produced easily and inexpensively. A method for producing deuterium-depleted water by removing heavy water and semi-heavy water from water includes an adsorption step of supplying water vapor to a predetermined adsorbent at pressure at which heavy water and semi-heavy water are adsorbed by the adsorbent and light water is not easily adsorbed, causing the heavy water and semi-heavy water to be adsorbed, and recovering the water vapor not adsorbed by the adsorbent. The method also includes a desorption step of maintaining vapor pressure around the predetermined adsorbent which has adsorbed the water vapor in a range in which light water is desorbed and heavy water or semi-heavy water is not easily desorbed, and recovering the water vapor desorbed from the adsorbent.

摘要： The invention refers to a process and an installation for obtaining the deuterium depleted water which is preferably for food use. The process consists in that water, after purification feeds the continuous isotopic distillation in the presence of a packing on minimum 100 theoretical plates with an efficiency of 8 theoretical plates per meter, the reflux being introduced on the last plate of an upper stripping zone, the number of theoretical plates from the stripping zone and that of the ones from a lower enrichment zone being in a ratio of 10 : 1 and preferably of 9 : 1 , in this latter case resulting 10.5% of the reflux flow as a waste which flows through the enrichment zone with a concentration of under 200 ppm D/(D+H), obtaining 4.5% of the reflux flow deuterium depleted water with a concentration of 20-30 ppm D/(D+H) which is mineralized. The installation in which the process is applied contains a packing consisting of a lower enrichment zone and an upper stripping zone, at the intersection of these zones a and b being connected a thermally insulated isotopic distillation column, between the steam boiler and the column being fitted a level regulating loop (A) placed under the zone in which are injected in the column the vapors provided by the steam boiler, between the vacuum ramp and the top zone (d) and respectively a secondary condenser being connected a vacuum regulation loop (B), the collecting pipe being connected to an intermediate storage tank at which another pipe is connected, fitted with a dosing device, communicating with a mixing pipe provided with static mixing promoters, to which a short pipe is connected provided with another automatic dosing device, connected to a storage tank for a mineralizing additive and a final evacuation pipe connected to a UV sterilizing subsystem.

摘要： An electrolytic pre-enrichment of a feed stream to a combined electrolysis and catalytic exchange ("CECE") heavy water production process. A deuterium enriched liquid or vapour stream from electrolytic cells is applied as a feed of the first stage of a CECE deuterium enrichment process. By deploying a portion of available electrolytic cell capacity in the pre-enrichment stage, advantages are achieved, particularly where available electrical power fluctuates or when a "turned down" CECE process is desired.

摘要： An electrolytic enrichment method for heavy water includes enriching heavy water by electrolysis using an alkaline water electrolysis cell including an anode chamber that holds an anode, a cathode chamber that holds a cathode, and a diaphragm. In the method, an electrolyte prepared by adding high-concentration alkaline water to raw material water containing heavy water is circularly supplied to the anode chamber and the cathode chamber from a circulation tank; an anode-side gas-liquid separator and an anode-side water-seal device are connected to the anode chamber, and a cathode-side gas-liquid separator and a cathode-side water-seal device are connected to the cathode chamber; and electrolysis is continued while the alkali concentration in the electrolyte supplied to both electrolysis chambers is maintained at a constant concentration by circularly supplying, to the circulation tank, the electrolyte from which the gas generated from the anode-side gas-liquid separator and the cathode-side gas-liquid separator is separated.

摘要： A hybrid BHW-CIRCE process heavy water production system in which most or all of the CECE upper stages of the CIRCE process are replaced with BHW liquid phase catalytic exchange stages. The system allows the CIRCE process to return to a more natural cascade resulting in a more cost effective process.
