CNG is still an important fuel choice today because it’s good for the environment and can save money.

Properties of CNG

Compressed Natural Gas (CNG full form) has several important qualities that make it a great fuel for different uses:

1. Physical State: It’s a clear gas that you can’t see, smell, or taste. Adding special scents to other fuels makes it safer because it is easier to notice leaks.
2. Chemical Composition: Mostly made of methane (CH4), which is a simple type of gas.
3. Non-corrosive & Non-toxic: It doesn’t harm materials it touches, and it’s safe for people when it’s in the air.
4. Low Greenhouse Gas Emissions: When burned, CNG makes fewer greenhouse gases compared to fuels like gasoline.
5. High Auto-ignition Temperature: It needs a higher temperature to catch fire on its own, which makes it safer than some other fuels.
6. Low Flammability Range: It only burns in a narrow range of air and gas mixtures (5.3-15%).
7. Lighter Than Air: If it escapes, CNG quickly goes up into the air instead of staying close to the ground where it could catch fire.
8. Stored Under High Pressure: They squeeze CNG into a small space using high pressure, making it take up much less room in tanks on vehicles.

How CNG is Compressed and Stored

1. Extraction and Purification: Companies extract and purify natural gas to obtain methane as the main component.
2. Compression: They then compress it using high-pressure compressors to reduce its volume.
3. Storage: Companies store CNG in specially designed tanks under high pressure, ensuring safe transportation and storage.

Composition

Natural gas, the raw material for CNG, consists primarily of methane (CH₄), which comprises about 70-90% of its composition. Methane is a simple hydrocarbon with one carbon atom and four hydrogen atoms. The other components of natural gas include:

• Ethane (C₂H₆): Another hydrocarbon, usually present in smaller quantities.
• Propane (C₃H₈) and Butane (C₄H₁₀): Natural gas processing often separates out these heavier hydrocarbons, which are present in trace amounts.
• Nitrogen (N₂): An inert gas that is often found in small amounts.
• Carbon Dioxide (CO₂): A non-combustible gas that is also found in small quantity.
• Water Vapor: During processing, operators usually remove any remaining moisture to avoid pipeline corrosion and freezing in cold conditions.
• Trace amounts of other gases: These can include hydrogen sulfide (H₂S), helium, and other gases depending on the source of the natural gas.

The high methane content is what makes natural gas and CNG particularly valuable as a clean fuel, as methane burns more cleanly than other hydrocarbons, producing fewer pollutants.

How is CNG Produced?

Extraction

Natural gas, used to make CNG, comes from deep underground. Here’s how it’s done:

1. Finding the Gas: Scientists use special tools and methods to find underground places where natural gas is likely to be found.
2. Drilling Wells: Large machines called drilling rigs dig deep holes, sometimes miles into the ground, to reach the gas.
3. Getting the Gas Out: Once they reach the gas, it flows up through the well. Sometimes they use methods like hydraulic fracturing (fracking) to help release more gas from the rocks.

After bringing the gas to the surface, operators subject it to a cleaning process to remove impurities such as water and other unwanted chemicals.

Compression

To convert natural gas into CNG, you have to compress or squeeze it into a smaller volume. This is how it works:

1. Using Compressors: Machines called compressors squeeze the natural gas to very high pressures, usually between 200 and 250 bar (about 2900 to 3600 pounds per square inch).
2. Reducing Volume: This compression shrinks the gas to less than 1% of its normal size, making it much easier to store and transport.

Storage and Distribution

Once we compress natural gas into CNG, we need to store and transport it safely.

1. Storing CNG: They keep CNG in strong, high-pressure containers, often made of steel or durable composites. These containers are designed to handle the high pressure without leaking.
2. Transporting CNG: There are two main ways to transport CNG.
   • Pipelines: Directly through pipelines from the source to the point of use.
   • Vehicles: In specially designed trucks or trailers that carry the high-pressure containers.
3. Distribution: When CNG reaches fueling stations or factories, operators dispense it from these containers into vehicles or equipment through safe and controlled systems.

CNG requires special infrastructure, like pipelines and fueling stations, to be readily available to customers. This infrastructure helps ensure that CNG is accessible and easy to use for people and businesses looking for cleaner fuel options.
