Similarly to ice, gas hydrates can be used to purify water from contaminants. The removal efficiency depends of several parameters, such as the chemical composition of the contaminant, its geometry and size, its charge and others. The process was tested for water mixtures containing glucose at different concentrations, ranging from 40 to 0.15 w/w%. To process meaningful quantities of water, the production of hydrates must be abundant. Therefore, CO2 hydrates were formed at seven different concentrations within the previously mentioned range. Only the concentrations corresponding to the best performances were selected to carry out experiments finalized at defining the removal efficiency of the process. For this second scope, hydrates were formed again, separated from the remaining liquid phase and then melted. The obtained water was analysed and the concentration of glucose measured. The comparison between the initial and the final concentrations, allowed to define the overall feasibility of the process.

通过形成 CO2 水合物和分离熔化，从浓度范围为 40 至 0.15 w/w% 的水混合物中去除葡萄糖


与冰类似，天然气水合物可用于净化水中的污染物。去除效率取决于几个参数，例如污染物的化学成分、几何形状和大小、电荷等。该工艺测试了含有不同浓度葡萄糖（范围为 40 至 0.15 w/w%）的水混合物。为了处理大量水，水合物的产量必须充足。因此，在上述范围内以 7 种不同的浓度形成 CO2 水合物。仅选择与最佳性能相对应的浓度来进行实验，最终确定工艺的去除效率。对于第二个范围，再次形成水合物，与剩余的液相分离，然后熔化。分析获得的水并测量葡萄糖浓度。初始浓度和最终浓度之间的比较可以定义该过程的总体可行性。
