摘　　要：使用BWRS状态方程,推导出了计算焦耳-汤姆逊系数的完整公式,给出了详细的计算步骤。实例计算表明,BWRS方法对单组分烃类气体、单组分非烃类气体和由烃类组分与非烃类组分组成的天然气均适用。与LKP方法和SRK方法相比,BWRS方法计算简单,精度较高,可以为输气管道和天然气轻烃回收中的节流温降计算提供理论依据。Based on the BWRS state equation,the complete formula for calculation Joule-Thomson coefficient is derived,and the detail calculation procedure is given.The examples show that BWRS method is available at single component hydrocarbon gas,single component non-hydrocarbon gas,and the natural gas made up of hydrocarbon component and non-hydrocarbon component.Compared with LKP and SRK methods,BWRS method is simpler and higher precision.The BWRS method in the essay provides the theory base for the throttle temperature drop calculation in natural gas transmitted by pipeline and lighter hydrocarbon recovery.
