石油馏分气体热容计算方法的考察

Investigation of Calculating Methods for Gas Thermal Capacities of Petroleum Fractions

利用胜利和辽河原油馏分油气体热容、分子量、密度等实测数据,考察石油馏分气体热客的7个计算式对国产原油的适用性,并列出了详细结果.其中以API式、Kesler-Lee式和Charli式更适合于国产原油馏分的气体热容的估算.

Suitabilities of 7 calculating methods for gas thermal capacities of petroleum fractions to domestic crudes were investigated by measuring such data as gas thermal capacity, molecular weight and density of Shengli and Liaohe petroleum fractions, and detailed results were listed. Among these methods, the API, Kesler-Lee and Carli equations are more suitable for the esti-mation of gas thermal capacities of domestic petroleum fractions.
