CNG VERSUS OTHER FUELS
Here are some of the available fuels available in the market :
CNG (Compressed Natural Gas)
CNG (Compressed Natural Gas) is a compressed form of natural gas, mainly composed of methane (CH4) that can be used as an alternative energy for fossil fuel such as: Marine Fuel Oil (MFO), Diesel Fuel, Liquefied Petroleum Gas (LPG) or Gasoline (Petroleum). CNG is made by compressing natural gas obtained from pipeline. It is stored and distributed in tube skids (CNG Storage Modules) at a pressure of 200 – 250 bar (2900 – 3600 psi).
MFO (Marine Fuel Oil)
MFO (Marine Fuel oil) is a fraction obtained from petroleum distillation, either as a distillate or a residue. Broadly speaking, Marine Fuel Oil is any liquid petroleum product that is burned in a furnace or boiler for the generation of heat or used in an engine for the generation of power, except oils having a flash point of approximately 40 °C (104 °F) and oils burned in cotton or wool-wick burners.
Diesel Fuel (Solar)
Diesel Fuel is any liquid fuel used in Diesel Engines. The most common is a specific fractional distillate of petroleum fuel oil, but alternatives that are not derived from petroleum, such as biodiesel, biomass to liquid (BTL) or gas to liquid (GTL) diesel, are increasingly being developed and adopted.
LPG (Liquefied Petroleum Gas)
LPG (Liquefied Petroleum Gas) is a flammable mixture of hydrocarbon gases, primarily propane and butane used as a fuel in heating appliances and vehicles. It is increasingly used as an aerosol propellant and a refrigerant, replacing chlorofluorocarbons in an effort to reduce damage to the ozone layer.
Gasoline is a petroleum-derived liquid mixture which is primarily used as a fuel in internal combustion engines. It is also used as a solvent, mainly known for its ability to dilute paints. It consists mostly of aliphatic hydrocarbons obtained by the fractional distillation of petroleum, enhanced with iso-octane or the aromatic hydrocarbons toluene and benzene to increase its octane rating. Small quantities of various additives are common, for purposes such as tuning engine performance or reducing harmful exhaust emissions. Some mixtures also contain significant quantities of ethanol as a partial alternative fuel. Most current or former Commonwealth countries use the term petrol, abbreviated from petroleum spirit. In North America, the substance is called gasoline, a term often shortened in colloquial usage to gas.
