Special Issue Information

Dear Colleagues,

The energy and gas infrastructure serves as the backbone of global energy supply chains, underpinning economic development, industrial production, residential comfort, and critical social services. Its seamless operation is inherently intertwined with public safety, environmental protection, resource efficiency, and energy security, including industrial accidents, environmental pollution, supply shortages, and significant economic losses. As energy and gas systems become increasingly complex, integrated, and exposed to evolving operational challenges, the need for robust process safety frameworks and advanced condition monitoring technologies has never been more pressing. Process systems engineers, safety specialists, and infrastructure operators are at the forefront of addressing these challenges, leveraging innovative approaches to mitigate risks, enhance reliability, and ensure the sustainable operation of energy and gas infrastructure.

Advances in process safety and condition monitoring for energy and gas infrastructure span a wide range of scales and technologies. From large-scale cross-border pipelines, liquefied natural gas (LNG), carbon dioxide (CO2) terminals , and gas processing plants to distributed energy systems, storage facilities, and municipal gas networks, each segment demands tailored safety strategies and monitoring solutions. The technologies involved are equally diverse, encompassing traditional methods such as pressure, temperature, and flow sensing, as well as cutting-edge innovations including predictive analytics, machine learning-driven anomaly detection, real-time data acquisition systems, remote monitoring tools, non-destructive testing techniques, and digital twins. These technologies work in tandem to enable proactive risk identification, real-time operational oversight, and data-driven decision-making, transforming safety management from a reactive to a preventive paradigm.

Process safety and condition monitoring are not only about risk mitigation but also about optimizing operational efficiency. By continuously monitoring the condition of key components (such as pipelines, valves, compressors, and storage tanks), operators can predict potential failures, schedule maintenance activities strategically, minimize unplanned downtime, and reduce operational costs. Moreover, integrating process safety data with environmental, economic, and operational metrics facilitates comprehensive techno-economic analyses and life cycle assessments, supporting the development of more sustainable and resilient energy and gas infrastructure.
This Special Issue on “Process Safety and Condition Monitoring for Energy and Gas Infrastructure” aims to curate cutting-edge research, practical case studies, and innovative technologies that advance the field of process safety and condition monitoring in energy and gas systems. We welcome contributions that address the theoretical, methodological, and practical aspects of process safety management, condition monitoring, risk assessment, and reliability optimization for energy and gas infrastructure. To maximize the impact and reproducibility of the published work, authors are invited to deposit relevant datasets, monitoring protocols, simulation models, or code in open-access repositories or provide them as supplementary material. These may include sensor data sets, risk assessment frameworks, machine learning models for anomaly detection, simulation files for process safety analysis, or case study documentation of real-world applications.

Topics include, but are not limited to:

  • Advanced condition monitoring technologies (sensors, remote sensing, non-destructive testing) for energy and gas infrastructure components.
  • Process safety risk assessment, mitigation strategies, and accident prevention in gas processing, transmission, and storage systems.
  • Machine learning, artificial intelligence, and data analytics for predictive maintenance and anomaly detection in energy and gas infrastructure.
  • Digital twins and simulation-based approaches for process safety optimization and condition monitoring.
  • Safety and monitoring challenges in the integration of renewable energy with traditional gas infrastructure.
  • Regulatory frameworks, standards, and best practices for process safety and condition monitoring in the energy and gas sector.
  • Case studies on process safety incidents, post-incident analysis, and improvement measures for energy and gas facilities.
  • Resilience assessment and enhancement of energy and gas infrastructure through advanced safety and monitoring systems.

We look forward to receiving your contributions and fostering a comprehensive dialogue on advancing process safety and condition monitoring for the future of energy and gas infrastructure.

Within the carbon capture, utilization and storage (CCUS) chain, buried CO2 pipelines are an indispensable engineering solution under complex topographic conditions. Experimental investigations show that leakage from buried supercritical CO2 (sCO2) pipelines features a two-stage pressure decline: an initial rapid drop driven by high leaking medium mass flow, followed by a linear decrease governed by homogeneous liquid CO2 vaporization. Notably, the choking flow effect homogenizes linear pressure drop rates across distinct experimental conditions. Leakage orifice diameter is a dominant factor for pipeline temperature distribution: small orifices yield consistent temperature drop rates at different vertical pipeline positions, while larger ones cause faster cooling at the pipeline bottom, forming significant vertical temperature gradients that intensify closer to the leakage orifice. Leakage direction and initial pipeline pressure are key regulators of leakage dynamics: vertical upward leakage (0°) leads to faster pressure drops due to the reduced soil resistance, and elevated initial pressure not only intensifies the pressure drop rate and amplifies CO2’s endothermic effect but also modulates the phase transition pathway of sCO2 during leakage.
