【摘要】 用自己设计、制造的测量装置,测定了大庆、胜利原油的热容—温度关系。根据试验数据分析了石蜡潜热及析蜡对热容的影响,整理出三个温度区间的经验公式,讨论了热容—温度关系对管道温降、总传热系数、常温储运等工艺计算的影响。更多还原

【Abstract】 The measurement was made of the relationship between specific heat and temperature of the crude oil in Da Ching and Sheng Li fields by using self made a device. Based on test data it makes an analysis of the impact of the wax potential heat and precipitation upon specific heat, presents experience equations in relation to three temperature ranges, and comments on the impact of the relationship between specific heat and temperature upon the technological calculation of pipeline temperature drop, general heat transmission coefficient, normal temperature trasportation, etc.更多还原
