    摘要： The present invention envisages a method for the recovery of phosphorus from waste incineration ash comprising a) a step of digesting the ashes with a 20-40% sulfuric acid solution, making a first solid phase and a first liquid phase, b) a step of continuously separating, without energy consumption, of the liquid and solid phases, c) a step of chemical precipitating, thermally coupled to the digesting of the ashes of step a), of the phosphate ions of the first liquid phase, by means of the addition of lime, until reaching a pH of 4.0-4.5, obtaining a second liquid phase, rich in acid, and a second solid phase, made up of phosphates and sulfates and d) a step of continuously separating, without energy consumption, of the second liquid and solid phase, the latter being the final product. Likewise, the installation for carrying out said method is envisaged.

    摘要： Provided is an industrially feasible method for separating tritiated water from light water. The method comprises: a step of removing tritiated water and heavy water from light water by adding heavy water to a liquid mixture containing tritiated water and light water, by converting into a gas hydrate consisting essentially of tritiated water and heavy water as the crystal structure under a condition of converting into the gas hydrate of at least one of heavy water and tritiated water, and yet keeping light water in the liquid state, and a step of separating tritiated water from heavy water by breaking the gas hydrate structure containing tritiated water and heavy water, so as to get a liquid mixture, by converting the liquid mixture containing tritiated water and heavy water into a gas hydrate containing tritiated water in the crystal structure under a condition of converting into a gas hydrate containing tritiated water in the crystal structure and yet keeping heavy water in the liquid condition and then, by breaking the gas hydrate structure of tritiated water, so as to collecting tritiated water in that order.
