Abstract
The production of gas hydrates is a widely recognised technique for impurities removal from waste water. Similar to ice, hydrate crystals cannot include ions and other impurities dissolved in water. Therefore, their formation, separation from the liquid phase and following dissociation, leads to the production of two distinguished liquid phases: the first, obtained from hydrate dissociation, which theoretically consists of demineralised water; the second, or the remained water, having a concentration of impurities higher than its initial values. However, mainly due to the stochastic nature of the hydrate formation process, the feasibility of such a strategy has not been completely validated yet, especially for substances different from ions. This study investigates the possibility of forming carbon dioxide hydrates to remove glucose (at different initial concentrations) from water. In order to achieve a satisfying treatment of water, two parameters were investigated: the effective capability of hydrates to produce decontaminated water and the abundancy of treated water, or the quantity of hydrates produced as a function of the initial glucose concentration in the liquid phase.
