As fuel costs continue to rise and vehicle emissions standards grow increasingly stringent, many are turning to natural gas as an alternative to gasoline or diesel. Natural gas provides comparable amounts of power and acceleration while producing lower levels of emissions and particulates, all at a significantly lower cost.
The benefits of utilizing compressed natural gas (CNG) powered vehicles and fueling systems in heavy-duty applications include:
Leaving the challenge of creating a fueling infrastructure and sourcing CNG-powered vehicles aside, the actual design of a CNG-powered system requires different approaches. Natural gas must be filtered at each step throughout the extraction and delivery process. At the wellhead and beyond, filters remove excess moisture, particulates, and chemicals used to treat, or "sweeten" the gas stream. A range of various filters, such as those from Parker Racor, cleans the gas before it is compressed and removes any contaminants that it picks up in the pipeline. They also clean it one last time as it goes into a dispenser for use in a vehicle to ensure that it is as clean as possible and will not damage the vehicle's fuel system.
In addition to filtration, Parker also offers sealing solutions for CNG vehicles and fueling systems. Given that CNG is lighter than air, leaks are both harder to identify and more difficult to contain. At the same time, CNG-fueled vehicles are exposed to extreme ambient temperatures, from arctic cold to desert heat. As such, a CNG fuel system requires special seals and hoses. CNG-capable compounds exhibit wide operating temperature ranges, high degrees of elasticity and high tensile strength ratings.
From the filler neck and fuel tank to the fuel filtration and conveyance system, CNG vehicle and fueling system solutions from Parker help to make this exciting technology possible.
