Companies are required to conduct regular LDAR surveys, with the frequency depending on the type of facility and its methane emission potential. For example, high-risk facilities must be surveyed quarterly, while low-risk facilities may be surveyed annually.
LDAR Techniques and Methodologies
Portugal’s methane regulation encourages the use of advanced LDAR techniques and methodologies to ensure the most effective leak detection and repair. Companies can choose from a range of proven techniques, each with its own strengths and limitations. Some of the most common LDAR techniques include:
Optical Gas Imaging (OGI)
Optical Gas Imaging (OGI) is a highly effective LDAR technique that uses infrared cameras to visualize methane leaks. OGI cameras can detect methane emissions from a distance, making them ideal for surveying large facilities or hard-to-reach areas. The regulation specifies the minimum sensitivity and performance requirements for OGI cameras to ensure reliable leak detection.
Flame Ionization Detectors (FID)
Flame Ionization Detectors (FID) are portable devices that can accurately measure methane concentrations in the air. FIDs are particularly useful for pinpointing the exact location of a leak, as they can provide real-time readings. The regulation requires companies to use FIDs with a minimum detection limit of 5 parts per million (ppm) to ensure accurate leak identification.
Acoustic Leak Detection
Acoustic Leak Detection is a non-invasive technique that uses high-sensitivity microphones to detect the unique sound of methane leaks. This method is particularly effective for identifying leaks in underground pipelines or other hard-to-access areas. The regulation specifies the minimum sensitivity and frequency range for acoustic leak detection equipment.
Soap Bubble Screening
Soap Bubble Screening is a simple yet effective LDAR technique that involves applying a soap solution to potential leak points and observing bubble formation. This method is often used as a first-line screening tool to quickly identify leaks before employing more advanced techniques. The regulation requires companies to use soap solutions with a minimum bubble formation rate of 50 bubbles per minute for reliable leak detection.
LDAR Survey Frequency
The frequency of LDAR surveys is a critical factor in the effectiveness of leak detection and repair programs. Portugal’s methane regulation sets clear requirements for survey frequency based on the type of facility and its methane emission potential. The minimum survey frequencies are as follows:
Facility Type | Survey Frequency |
High-risk facilities | Quarterly |
Medium-risk facilities | Semi-annually |
Low-risk facilities | Annually |
Companies must also conduct additional surveys following any significant process changes or equipment modifications that could potentially increase methane emissions. This ensures that any new leaks are identified and repaired promptly.
Leak Definition and Classification
- Category 1: Leaks with a methane concentration of 50,000 ppm or higher
- Category 2: Leaks with a methane concentration between 10,000 and 49,999 ppm
