| 摘 要： | 介绍了一种H2S在醇胺水溶液与LPG中分布的测定方法，此方法可分析H2S摩尔分数低至0．0002％的含量(H2S摩尔分数范围0．0002％～5％，MDEA的摩尔浓度为3．0mol／L和4．2mol／L)。实验数据表明在LPG中H2S的摩尔分数低于1％时，其摩尔分数的对数与胺相中H2S负荷的对数近似呈线性关系。因此，可将H2S摩尔分数适当外推到0．0001％，来满足生产和设计的需要。

| Abstract: | A method for determing the solubity of H_2S between aqueous MDEA solution and LPG by an experimental apparatus was introduced. This method could analyze the content 0.0002% of the mole fraction of H_2S.It was found that when the mole fraction of H_2S in LPG was less than 1%, there was a linear relationship between logarithm of the acid loading and the logarithm of the mole fraction of H_2S.Therefore, the mole fraction of H_2S could be used as 0.0001% for the requirement of production and design. |
