作者按编制计算机程序要求,提出了莱特里赫—克伏格、霍尔—亚鲍勒夫、罗宾逊三种计算天然气压缩系数的方法。通过与司坦丁—凯茨图解法比较,推荐霍尔—亚鲍勒夫、罗宾逊计算天然气压缩系数。 According to the requirements of compiling computer program, the author proposed three methods of calculating natural gas compression coefficient, such as Rietlich-Kegger, Hall-Ya-Balluluo and Robinson. By comparing with the Steintenz-Katz plotting method, Hall-Yarapoloff and Robinson are recommended to calculate the natural gas compression coefficient.
