What is CNG?
- Compressed natural gas (CNG) is primarily methane. Natural gas also includes other hydrocarbons.
- One way to make transportation of natural gas cost-effective is to compress the natural gas to make the volume much smaller.
- CNG is loaded into specialty trucks for delivery to sites where natural gas is needed.
What is CNG Decompression?
- When high-pressure natural gas arrives at a site in a truck, the high-pressure gas needs pressure reduction.
- Similar to an air conditioner, reducing the gas pressure makes everything cold – so we add heat to the gas.
- Our control systems continually monitor process temperature, pressure and flow rates and transmit this data to an operations center. This data is needed for logistics purposes.
- The end user has the experience of having pipeline natural gas – it’s just that the pipeline is on wheels!
How Industrial CNG Works
Industrial CNG subsets:
- Central heat plants (large commercial-industrial facilities)
- High-horsepower (exploration & processing) field-service companies
- Emergency systems (backfilling for system disruptions)
- Community gas (providing natural gas to municipalities not connected to pipeline gas)
