ABSTRACT

For the Redlich–Kwong equation of state of real gas, which is widely used for description of behavior of hydrocarbon mixtures, the inversion curve, which determines the change in the throttling coefficient sign, is constructed. The reduced pressure and temperature variation ranges correspond to the characteristic values in natural gas production and transportation systems.

天然气生产和运输系统数学模型中的状态方程

摘要

对于广泛用于描述烃混合物行为的真实气体的Redlich-Kwong状态方程，构建了确定节流系数符号变化的反演曲线。减小的压力和温度变化范围对应于天然气生产和运输系统中的特征值。
