摘要
将一个饱和液体状态方程(TONG方程)应用于已知的双元液体混合物密度的推算,温度为105K～140K,该混合物的组分是低碳烷烃和氮,它们都是液化天然气(LNG)的主要成分。此模型方程利用纯组分数据来预测液化天然气低温下密度而被检验。本方法的优点是使用简便。
An equation of state for saturated liquids （TONG＇S EOS） was used to estimate saturated liquid densities of gravimetrically prepared binary mixtures containing the major components of liquefied natural gas （LNG）, i. e nitrogen and low-carbon alkanes, within the temperature range of 105K-140K. The model equation was tested for prediction of the saturated densities of LNG mixtures using all the pure components. The advantage of this method was simple and convenient in use.
