Leak Detection and Localization of Gas Pipeline Network Based on a Steady State Model

The safety operation of pipelines is extremely important in gas and petrochemical industries due to the financial cost and the potential environmental damage. In his sense, leakage detection in pipeline usage is of great value and should draw particular attention on. Among the various methods concerning the leakage detection, model-based algorithms are gaining an increasing popularity compared with other conventional ones. In this paper, an improved numerical method of gas detection with high accuracy is proposed. A considerate number of leakage location simulations are conducted based on data generated by professional simulation software Flow Master. The comparison of results of the conventional and the improved algorithm shows that the improved one performed better under various conditions in terms of location accuracy.
