📖 Introduction
What is Compressed Natural Gas (CNG)?
Compressed Natural Gas (CNG) is essentially natural gas that has undergone a process of significant compression. This compression allows it to occupy a much smaller volume, making it suitable for storage in fuel tanks, particularly for vehicles.
Compression Details: CNG is typically compressed at very high pressures, ranging from 200 to 250 kg/cm². This intense compression reduces its volume to less than 1% of its original size at atmospheric pressure, enabling efficient storage.
Composition of CNG
Unlike Liquefied Petroleum Gas (LPG), which is a blend of compressed propane and butane, CNG has a distinct composition. It primarily consists of methane, making up 80 to 90% of its content, and remains in a gaseous state even after compression.
CNG vs. LNG: Key Differences
The fundamental distinction between CNG and Liquefied Natural Gas (LNG) lies in their physical states. While CNG exists and is stored as a gas, LNG is natural gas cooled to an extremely low temperature to become a liquid, which is then regasified for use.
Physical State is Key: Remember that CNG is a gas under high pressure, whereas LNG is a liquid at cryogenic temperatures.
Understanding BioCNG
BioCNG, also known as biomethane, represents a renewable and environmentally friendly alternative. It is a clean-burning transportation fuel derived from organic waste materials.
The production of BioCNG involves upgrading biogas to achieve the same quality as conventional natural gas. This process makes it a sustainable fuel source, contributing to waste management and renewable energy goals.
BioCNG Attributes: It is a renewable fuel, produced from organic waste, and significantly contributes to reducing carbon footprint as a clean-burning fuel.
