【摘要】 Packie图广泛应用于预测原油常压塔产品分馏的精度。为了能够应用于计算机的模拟与计算,本文通过采用非线性回归和单纯形的加速算法拟合Packie图的"原油常压精馏塔塔顶产品与一线分馏精度图"和"原油常压精馏塔侧线产品分馏精度图",建立可用计算机计算的数学模型。该模型方程形式简单,并估计其模型参数误差。证明,该数学关联式的计算结果,跟两图得出的数据能够吻合,相关系数分别为0.9982697和0.999005,计算准确。更多还原

【Abstract】 Packie figures are widely applied to the forecasting of fractionation accuracy of atmospheric crude oil tower product.Computer applicable mathematic correlations were reached through fitting Packie Figures.Corresponding parameters and error analysis were compared,and the results show that the correlations were in good harmony with those figures and can be applied to the practical manufacturing.更多还原
