| Safety |
Natural gas is safer as it is lighter than air and so disperses upwards when leaking |
Flow on the ground when leaking |
Heavier than air and so remains on the ground when leaking |
| Usage |
As a gas, it can directly mix with air |
It needs an atomizer to mix it with air before combustion occurs |
It is a liquid that must be gasified before using |
| Combustion Efficiency |
Complete combustion, Natural Gas produces a better flame and leaves no residue that necessitates shut-downs for its removal |
It burns poorly and creates soot |
Better combustion than fuel oil and mix better with air |
| Environmental Impact |
Natural Gas is cleaner and less polluting |
It burns poorly and creates soot, acid gases and more CO2 |
Its combustion is complete and creates no soot |
| Fuel Quality |
Colorless and pure so direct fired combustion by Natural Gas has no adverse effect on products and processes
Natural Gas is odorless but odorant is added for safety reason
Extreme low sulfur content, no vanadium, hence no corrosion of the appliances |
Its color and odor may affect the manufacturing processes and products quality
Substantial sulfur content and higher vanadium concentration, thus corrosion of the appliances can occur |
Colorless and pure so direct fired combustion by LPG has no adverse effect on products and processes
LPG is odorless but odorant is added for safety reason
