CNG

Compressed Natural Gas (CNG)

CNG is a Fossil Fuel comprised of 87 to 92 percent of methane and is one of the cleanest burning fuel. A natural gas that has been compressed at 200 to 250 bar pressure, which remains clear and non-corrosive. It’s an alternate fuel to Diesel, petrol and Black oil. Against diesel, CNG is 45 to 50 % cheaper (depending on customer’s location). CNG on wheels act as a virtual pipeline for the consumers. Compressed Natural Gas (CNG) is a clean and efficient alternative to conventional fossil fuels like gasoline and diesel. It is primarily composed of methane and is stored and distributed in a compressed form. Versafusion Global Limited is committed to delivering clean and cost-effective natural gas to power generation companies, heavy industries, commercial complexes and residential estates.

​CNG Availability for Versafusion is most reliable in the market due to its “Dual Source” Concept which guarantees continuous gas supply to all client sites and uses real-time remote monitoring technology to ensure our customers are always supplied Natural Gas.

CNG Production

Natural Gas Extraction

The production of CNG begins with the extraction of natural gas from underground reservoirs. Natural gas is found in deep underground rock formations or associated with other hydrocarbon reservoirs in coal beds and shale formations. The extraction process involves drilling wells and using various techniques to bring the gas to the surface.

Processing

Once extracted, natural gas is processed to remove impurities and by-products, such as water vapor, hydrogen sulfide, carbon dioxide, and other hydrocarbons. This processing typically involves several steps:

  • Separation: Removing liquid hydrocarbons and water.
  • Dehydration: Removing water vapor using glycol dehydration or other drying methods.
  • Sweetening: Removing hydrogen sulfide and carbon dioxide.
  • Fractionation: Separating different hydrocarbon components.

Compression

After processing, natural gas is compressed to high pressures (typically 200-250 bar or 2,900-3,600 psi) to reduce its volume for storage and transportation. This is done using industrial-grade compressors designed to handle high pressures and maintain the purity of the gas.

CNG Storage

Storage Methods

CNG is stored in high-pressure cylinders or tanks, which can be stationary (fixed at a fueling station or facility) or mobile (onboard vehicles). The storage methods include:

  • Cylinder Storage: CNG is stored in cylindrical tanks made of steel, aluminum, or composite materials. These cylinders are designed to withstand high pressures and are equipped with safety features.
  • Storage Cascades: A series of interconnected cylinders used at fueling stations to store large volumes of CNG. Cascades allow for efficient filling of vehicles by maintaining pressure levels.

Safety and Regulations

Storage of CNG requires adherence to strict safety standards and regulations to prevent leaks and ensure the safety of personnel and the public. Key safety measures include:

  • Pressure Relief Devices: Installed on cylinders to release gas safely if pressure exceeds safe limits.
  • Leak Detection Systems: Continuous monitoring for gas leaks using sensors and alarms.
  • Regular Inspections: Routine checks and maintenance to ensure the integrity of storage systems.

CNG Distribution

Distribution Infrastructure

The distribution of CNG to clients involves a well-developed infrastructure, including pipelines, compressors, and fueling stations. The primary components are:

  • Pipelines: Transport natural gas from production sites to processing plants and compression facilities. High-pressure pipelines are used to distribute CNG to various locations.
  • Compression Stations: Facilities where natural gas is compressed to CNG. These stations are strategically located to serve multiple clients.
  • Fueling Stations: Public and private stations equipped with CNG dispensers for refueling vehicles. These stations can be fast-fill or time-fill, depending on the refueling needs.

Transportation

In addition to pipelines, CNG can be transported using mobile storage units, such as tube trailers and ISO containers. These methods are useful for areas not served by pipelines or for emergency supplies:

  • Tube Trailers: Large trailers with multiple high-pressure cylinders used to transport CNG over long distances.
  • ISO Containers: Standardized containers designed for transporting CNG by road, rail, or sea.

Distribution to Clients

The distribution of CNG to clients includes several steps to ensure a continuous and reliable supply:

  • Demand Forecasting: Analyzing client usage patterns to predict future demand and ensure adequate supply.
  • Logistics Management: Coordinating the transportation and delivery of CNG to meet client requirements.
  • Customer Support: Providing technical support and maintenance services to ensure safe and efficient use of CNG.
