A fugitive emission test is performed using either helium or methane gas depending on the test procedure, each of which has its respective limitations. It measures emissions to the atmosphere at maximum operating conditions of the product (temperature and pressure). Southwest Research Institute is actively involved in fugitive emissions testing across the oil and gas industry.
Fugitive emission test procedures for valves, flanges, and other products are governed by several industry standards. Tests can be performed from cryogenic temperatures of -320°F (liquid nitrogen submersion) to temperatures higher than 800°F. All fugitive emissions testing is performed under a quality/safety system with qualified operators.
Fugitive Emission Test for Control Valves & Isolation Valves
SwRI provides standard and custom fugitive emission test for control valves solutions, including:
- ISO 15848-1– Measurement, Test, and Qualification Procedures for Fugitive Emissions, Classification System, and Qualification Procedures for Type Testing of Valves
- ISO 15848-2 – Measurement, Test, and Qualification Procedures for Fugitive Emissions, Production Acceptance Test of Valves
- MESC SPE 77/300 – Procedure and Technical Specification for Type Acceptance Testing (TAT) of Industrial Valves
- MESC SPE 77/312 – Fugitive Emission Production Testing (Amendments/Supplements to ISO 15848-2)
- API 624 - Type Testing of Rising Stem Valves Equipped with Graphite Packing for Fugitive Emissions
- API 641 - Type Testing of Quarter-turn Valves for Fugitive Emissions
- Custom test procedures can be accommodated based on the project requirements
Cryogenic Test for Valves
Performing a cryogenic test for valves and other products used in the oil and gas industry may entail full immersion in liquid nitrogen immersion (-320°F). SwRI performs cryogenic testing to meet standardized tests or design and fabricate custom test chambers, including:
- BS 6364 – Specification for Valves for Cryogenic Service
Natural Gas Pipeline Leak Detection
SwRI performs natural gas pipeline leak detection with automated Methane Leak Detection and a reciprocating compressor flow loop, which recreates real-life gas pipeline pressures, temperatures and horsepower levels. The flow loop is available for R&D and testing and plays a central role in our efforts to reduce methane emissions. The facility is available for compressor valve testing, advanced pulsation control, lubrication optimization for reciprocating compressors and drivetrain dynamic studies.
