Natural Gas Analysis for CNG / LNG Engine Efficiencies

Key performance specifications, such as thermal efficiency, of CNG / LNG engines can be determined by comparing input and output gross heating values in British Thermal Unit per cubic feet (BTU/cu.ft.). The exact composition of natural gas supplies (and hence the gross heating value) may change daily, weekly or monthly. Quick and exact analysis of the chemical composition and physical properties of natural gas is critical for CNG / LNG engine manufacturers to obtain precise values.

Micro GC Fusion reports gas component data in mole percentage, which is critical for understanding fuel composition and is used to calculate the gross heating value, among other physical property calculations. The Micro GC Fusion analysis ensures changes in composition are tracked quickly. High quality analytical data is beneficial for product development, performance, environmental compliance, and reporting.

The web-based Micro GC Fusion user interface combined with Diablo EZReporter software automatically calculates chemical composition and physical properties after each run, allowing accurate determination of gross heating values. The EZ Reporter software generates standard reports using industry specific methods from one of the following standards:

• GPA (Gas Midstream Association) 2172, 2145
• ASTM (American Society of Testing and Materials) 03588
• ISO (International Standards Organization) 6976

Diablo EZReporter software exports data to both PDF reports and a customizable, appending CSV file. This file can then be used by other programs to import data from Micro GC Fusion.

Micro GC Fusion complies with the requirements of ASTM 1945 and GPA 2261 Gas Chromatography based methods for natural gas analysis. With its precision, small size, and speed of analysis, Micro GC Fusion is the ideal BTU analyzer and may be considered an advanced technological upgrade to legacy calorimeters.
