摘要

The transition toward more sustainable industrial systems requires not only reducing emissions but also improving the efficiency and resilience of existing energy infrastructures within a circular economy perspective. Although circular economy principles are commonly associated with waste management and product design, their application to large scale energy transport systems remains insufficiently explored. In hydrocarbon-producing countries, pipeline networks play a central role in ensuring the safe and continuous transport of resources such as liquefied petroleum gas (LPG). From a material efficiency standpoint, maintaining stable operation of these infrastructures is essential to minimize product losses, reduce unnecessary energy consumption, prevent premature equipment degradation, and extend asset lifetime. Operational disturbances, particularly the unexpected shutdown of a pumping station, may generate pressure imbalances, flow instability, and increased mechanical stress, potentially leading to resource inefficiencies and additional environmental burdens. In this context, predictive simulation tools provide a strategic solution by enabling operators to anticipate degraded conditions, optimize pressure management, and ensure transport continuity without costly physical interventions or infrastructure expansion. This study investigates the resilience of the 989 km LR1/DLR1/ELR1 LPG transportation network in Algeria under a critical pumping station shutdown scenario using Pipephase 9.6 and real operational data. Beyond hydraulic performance assessment, the work interprets operational resilience as a lever for improving material efficiency and supporting circular resource management in energy transport systems, thereby contributing to the long-term sustainability and optimized use of existing pipeline infrastructures. From a circular economy perspective, infrastructure resilience contributes to maintaining the functional value of existing assets, reducing premature equipment replacement, and minimizing material and energy losses. In large-scale LPG transport systems, operational optimization under degraded conditions avoids unnecessary oversizing, reduces energy penalties, and extends pump service life. Therefore, resilience assessment can be interpreted not only as a reliability metric but also as a circular strategy aimed at preserving material stocks and limiting resource dissipation.
