摘要
根据酸性气体粘度的预测方法,对比了基于PR状态方程的粘度模型、经验公式和图版法在预测酸性气体粘度时的准确性。同时,利用酸性气体对基于PR状态方程的粘度模型进行有效性校验。通过计算比较发现,基于PR状态方程的粘度预测模型误差较大,而LBC经验关系能较准确地确定酸性气体的粘度。
The accuracy of viscosity model based on PR state equation,empirical equation and chart method for predicting acidic gas viscosity is correlated.The effectiveness of the viscosity model based on PR state equation is tested using acidic gas.Calculation shows that the viscosity model based on PR state equation has big error,while LBC empirical relationship can provide more accurate viscosity of acidic gas.
