Who hasn’t been woken at dawn by a noisy trash collection truck? Sometimes it seems the rasping engine and whining hydraulics were designed specifically to rouse entire streets, but that’s changing. Growing numbers of trash collectors, like Waste Pro, are converting their fleets to compressed natural gas (CNG.) CNG offers several benefits, including quieter operation, but also raises some issues relating the refueling.
Our customers spread across a wide range of industries, but all depend on their ability to move liquids and gases through sophisticated equipment.
Ground-level ozone is a growing problem in many cities, especially on the US west coast. As noted by the EPA, it causes respiratory problems like throat irritation, tightness in the chest, and increased occurrence of asthma attacks. That’s why, on October 1st2015, the National Ambient Air Quality Standard was lowered from 75 to 70 ppbn. This has implications for the fuel burnt in automobile and truck engines, and supports increased use of compressed natural gas (CNG.) CNG for vehicles is delivered through specially-designed filling stations, which are good applications for ChemTec flow monitors and excess flow valves.
Public transportation across the country has been using CNG for decades, with about 12-15% of public transit buses in the U.S. currently running on natural gas (either CNG or LNG – liquefied natural gas). That number is growing, with nearly one in five buses on order today slated to run on natural gas. States with the highest consumption of natural gas for transportation are California, New York, Texas, Georgia, Massachusetts and Washington, D.C.
Natural gas is a domestically produced fossil fuel comprised mostly of methane. It is one of the cleanest burning alternatives to gasoline, diesel and propane and it can be used in the form of Compressed Natural Gas and Liquefied Natural Gas to fuel automobiles. CNG and LNG produce fewer undesirable gases than the alternative fuels and are also safer in the event of a spill because the natural gas is lighter and will disperse quickly when released.
