Abstract

Corrosion has severe consequences for the integrity of pipelines used in the petroleum industry. Modelling and optimising the parameters of a circulating fluid are two of the numerous methods for combating corrosion. The objective of this study was to develop a multiphase flow simulation model for estimating the corrosion rate of oil and gas pipelines, considering the erosional effect. In addition to carbon dioxide (CO2) and hydrogen sulphide (H2S) corrosion, the present model also takes into account the impacts of chloride concentrations. The current model evaluates and reflects a comprehensive understanding of corrosion in a saline environment, making it readily applicable for estimating corrosion rates for industrial applications. The model's results indicate a prediction accuracy of about 85%. Field data gathered under a broad range of environmental conditions confirms the model's prediction accuracy. The predictions from the present model are in good agreement with the field data. In addition, the present model was found to be more effective than the model created by Dewaard and Milliam. This research is likely to have widespread applications in the oil and gas industry for predicting more accurate corrosion rates.

基于多相流建模的油气管道腐蚀率预测

腐蚀会严重影响石油工业管道的完整性。建模和优化循环流体参数是抗腐蚀的众多方法中的两种。本研究的目的是开发一种多相流模拟模型，用于估算石油和天然气管道的腐蚀率，同时考虑侵蚀作用。除二氧化碳（CO2）和硫化氢（H2S）腐蚀外，本模型还考虑了氯化物浓度的影响。当前的模型评估并反映了对盐碱环境中腐蚀的全面理解，使其可随时用于估算工业应用中的腐蚀速率。该模型的结果表明，预测准确率约为 85%。在各种环境条件下收集的现场数据证实了该模型的预测准确性。本模型的预测结果与现场数据十分吻合。此外，本模型比 Dewaard 和 Milliam 创建的模型更有效。这项研究可能会在石油和天然气行业得到广泛应用，以预测更准确的腐蚀率。

期刊介绍： "International Journal of Engineering Research in Africa" is a peer-reviewed journal which is devoted to the publication of original scientific articles on research and development of engineering systems carried out in Africa and worldwide. We publish stand-alone papers by individual authors. The articles should be related to theoretical research or be based on practical study. Articles which are not from Africa should have the potential of contributing to its progress and development.
