We report measurements of the solubility of hydrogen in pure water and in sodium chloride brine of molality 2.5 mol/kg at temperatures between 323.15 K and 423.15 K and at pressures up to about 40 MPa. The estimated expanded relative uncertainty of the hydrogen solubility at given temperature and pressure is 3%, with a coverage factor of 2. The new results, together with data from the literature for hydrogen solubility in water and brine, are used to construct a simple model to predict hydrogen solubility in water and sodium chloride brines as a function of temperature, pressure and salt molality.

高压下氢气在氯化钠盐水中的溶解度

我们报告了在323.15 K和423.15 K之间的温度和最高40 MPa的压力下，氢气在纯水和浓度为2.5 mol / kg的氯化钠盐水中的溶解度的测量值。在给定的温度和压力下，氢溶解度的估计扩展相对不确定度为3％，覆盖因子为2。将新的结果以及文献中有关水和盐水中氢溶解度的数据用于构建简单模型预测氢气在水和氯化钠盐水中的溶解度与温度，压力和盐摩尔浓度的关系。
