CNG Quality Testing

Compressed Natural Gas (CNG) quality testing.

Compressed natural gas (CNG) quality can vary depending upon source, location, storage, and transportation methods. CNG can vary in chemical composition, which can effect fuel quality and engine performance and even CNG engine warranty protection.

Intertek laboratories routinely test natural gas and other hydrocarbons for fuel quality parameters, along with chemical and contamination trace analysis, on a regular basis. The labs test to ASTM, ISO, GPA, EPCA, SAE, and other industry accepted quality standards and test methods. Natural gas samples tested include CNG, Liquefied Natural Gas (LNG), well-head gas, and pipeline gases. Compressed natural gas field sampling and shipment options are available.

Available through a global network, lab analysis by Intertek personnel monitors CNG fuel quality, providing clients with data they need to help ensure natural gas fuel quality is acceptable and meets engine requirements.

Using gas chromatography, mass spectrometry, and other natural gas analysis methods, Intertek chemists analyze a wide range of components found in natural gas, including methane, ethane, propane, butane, hexane, heptane, octane, hydrogen sulfide, oxygen, nitrogen, and other trace gases and components.

Calculations and additional test results provide CNG heating value, sulfur content, and other quality control and contamination measurements.
