Why Filling LPG in a CNG Gas Kit is Unfeasible and Unwise
Efficient and eco-friendly, Gas Natural Gas (CNG) and Liquefied Petroleum Gas (LPG) are two popular options for fueling vehicles. However, it is crucial to understand that these two gases are fundamentally different. Incorrectly filling a CNG gas kit with LPG can lead to severe consequences, much like attempting to run a diesel car on petrol.
Differences in Gases and Storage Standards
Both LPG and CNG are vastly different from each other in terms of both composition and storage requirements. LPG is a mix of propane and butane, which requires a comparatively low pressure to remain in a gaseous state. In contrast, CNG is pure methane, which needs a higher pressure to maintain its gaseous form. This discrepancy in pressure and composition is the primary reason why these gases cannot be interchanged.
Storage Tank Design Considerations
Storage tanks are specifically designed for the unique storage pressure requirements of their respective gases. A CNG cylinder, for instance, is engineered to withstand pressures up to 200 bar. On the other hand, LPG cylinders are only designed for maximum pressures of around 17-18 bars. Tinkering with these settings can lead to dangerous situations, including gas leaks and explosions. Similar to trying to fit a truck tyre on a car, replacing one gas with the other is simply inappropriate and potentially disastrous.
Tank Compatibility
The compatibility issue between CNG and LPG extends beyond just the gas characteristics and the storage tanks. Regulators, which control the rate of gas flow, are also designed specifically for the type of fuel. Attempting to fit an LPG regulator into a CNG system or vice versa, would be like trying to fit a truck tyre onto a passenger car. This mismatch can lead to issues such as inadequate gas supply, inefficient engine performance, and even system failure.
Economic and Safety Implications
While CNG is generally more economical and environmentally friendly than LPG, running a CNG vehicle on LPG would defeat the purpose. Not only would it violate the economic benefits of CNG, but it could also result in safety hazards. Incorrectly filling a CNG gas kit with LPG can lead to issues such as reduced engine efficiency, potential gas leaks, and even engine damage. Therefore, it is important to adhere to the correct fuel for each type of storage tank to ensure optimal performance and safety of the vehicle.
