摘要
管道运输是运输原油及其产品的理想方式,在原油混合长输管道实施过程中,原油的物性参数对管道工艺设计有很大的指导作用,运用模型计算原油物性参数较实验获取有很大的优势,通过对比分析多个预测模型,最终采用刘天佑修正模型结合陈俊的经验公式计算混合原油的凝点,采用Cragoe修正模型结合蒋文学的经验公式计算混合原油的粘度,是混合原油参数计算较为精确的方法。
Pipeline transportation is the ideal means for the transportation of crude oil and its products.Physical property parameters for blended crude play a guidance role in process design.Calculation model is better than experiments in calculating the physical property parameters.after study,we calculate determining gel point of mixed crude by Liu Tianyou correction model combined with empirical formula of Chen Jun,and also,calculate the viscosity by Cragoe correction model combined with empirical formula of Jiang Wenxue,These are more accurate methods of physical property parameters.
