Abstract In this work, an accurate predictive correlation has been proposed, which presents an easy RVP estimating for a light crude oil with avoiding the expensive and time-consuming laboratory methods. The established correlation for predicting RVP of the investigated light crude oil depends on few physical properties inputs of API gravity and pseudocritical properties. The predicted RVP values have been evaluated with experimentally RVP measured data obtained for 745 light crude oil samples at 37.78 °C. The absolute average deviation (AAD %) and relative error (Er) of the predicted RVP using the proposed correlation are 3.61% and −0.337%, respectively.

使用简化和适当的相关性定量预测轻质原油的 Reid 蒸气压

摘要 在这项工作中，提出了一种准确的预测相关性，它提供了一种简单的轻质原油 RVP 估计方法，避免了昂贵且耗时的实验室方法。已建立的用于预测所研究轻质原油 RVP 的相关性取决于 API 重力和伪临界特性的一些物理特性输入。预测的 RVP 值已通过在 37.78 °C 下获得的 745 个轻质原油样品的实验 RVP 测量数据进行评估。使用建议的相关性预测 RVP 的绝对平均偏差 (AAD %) 和相对误差 (Er) 分别为 3.61% 和 -0.337%。
