Designing a reliable leak bio-detection system for natural gas pipelines

Area of Science:

• Environmental Science
• Sensor Technology
• Pipeline Engineering

Background:

• Natural gas (NG) pipeline monitoring is crucial for safety, economic operation, and environmental protection.
• Existing leak detection methods have limitations, driving research into new systems.
• Biosensors offer a low-cost, high-performance alternative for environmental monitoring when properly designed and networked.

Purpose of the Study:

• To develop and validate a robust cooperative scheme for natural gas leak surveillance.
• To integrate biosensors with conventional detectors for enhanced pipeline monitoring.
• To optimize the sensor network for reliable, granular information delivery.

Main Methods:

• A cooperative/synergistic scheme integrating biosensors and conventional detectors was proposed.
• In situ validation and optimization of the sensor network were performed.
• Fuzzy Multicriteria Analysis (FMCA) was employed for biosensor design selection based on target analyte and micro-environment.

Main Results:

• The proposed scheme demonstrated reliable natural gas leak surveillance capabilities.
• Network optimization achieved the required granularity for effective monitoring.
• FMCA successfully guided the selection of appropriate biosensor designs.

Conclusions:

• The cooperative biosensor and conventional detector scheme provides a reliable solution for natural gas pipeline leak detection.
• Optimized sensor network design and deployment are key to effective pipeline integrity management.
• This approach enhances safety, loss prevention, and environmental protection in pipeline operations.
