CNG and LPG

CNG stands for “Compressed Natural Gas,” whereas LPG stands for “Liquefied Petroleum Gas.” The fundamental distinction between CNG and LPG is found in the elements that constitute both fuels. While CNG is mostly composed of methane, LPG is predominantly composed of propane.

CNG

CNG, or compressed natural gas, is a much more sustainable alternative to gasoline. CNG fuel is superior to oil products and diesel fuel products since it is non-toxic and therefore does not pollute groundwater. It is created by compressed natural methane gas to far less than 1% of its original volume.

Advantages of CNG

• Green Fuel – Because it is devoid of lead and sulfur, it is commonly referred to as green fuel.
• Safe Fuel – CNG is a safe fuel because of its characteristics & properties.
• High auto-ignition temperature – Because CNG has a high auto-ignition temperature, it is less likely to auto-ignite on hot surfaces.
• Low operational cost – When compared to cars that run on other fuels, vehicles that run on CNG have a lower operational cost.
• Dual fuel capability – CNG vehicles can operate on both CNG and gasoline.
• Increased oil life – Another practical benefit seen is an improvement in the lifespan of lubricating base oil, as CNG does not pollute or dilute the crankcase oil.

LPG

LPG has a high burning or caloric component, which indicates that it produces a lot of heat in a short amount of time as an energy source. LPG also has almost little sulfur, resulting in cleaner burning. LPG, which is often offered in gas cylinders, is a handy, transportable source of energy that is simple to carry and store. LPG has a stable quality for industries. That means it’s dependable and consistent whether used in gas engines like forklifts or industrial boilers. LPG is also used in institutional, commercial, industrial, horticultural, and manufacturing & agricultural settings. It can offer us with warmth, hot water, and energy to cook our meals, as well as fuel for our automobiles.  It’s even used to power cogeneration.

Advantages of LPG

• LPG is the cleanest burning fossil fuel available.
• LPG is non-corrosive and less harmful.
• LPG is easily transportable through pipelines.
• LPG is widely accessible and reasonably priced.
• LPG is simple to store and transport.

Difference Between CNG and LPG

CNG

• CNG’s principal application is as a fuel substitute in vehicles.
• Methane is the major constituent of CNG.
• CNG emits fewer greenhouse emissions than other fuels (when compared with LPG).
• CNG is largely harmless since it disperses quickly into the atmosphere.
• CNG is mostly obtained from oil and gas wells & pipelines, bed methane boreholes, coal wellholes, and natural injection wells.

LPG

• LPG is used for a variety of purposes in the household, including heating and cooking. LPG is also used in industry and agriculture.
• LPG is mostly composed of propane and butane.
• LPG emits a significant quantity of carbon dioxide referred to as a greenhouse gas.
• Because LPG is significantly heavier than air, it is very combustible.
• The method of collecting natural gas from aquifers is the primary source of obtaining LPG.

Conclusion 

We discussed CNG, LPG, the difference between CNG and LPG, and other related topics through the study material notes on the difference between CNG and LPG. CNG is an abbreviation for compressed natural gas, which is technically pressed pure methane gas (CH4). It is applied to generate a clean fuel that is non-polluting and nearly more advantageous to the environment. LPG is an abbreviation for liquefied petroleum gas, which is a combination of light gaseous hydrocarbons such as propane, butane, and other light petrochemical products turned into a liquid under extreme pressure.
