Read Explanation:
Composition of LPG
- Liquefied Petroleum Gas (LPG) is primarily a mixture of flammable hydrocarbon gases, specifically Propane (C3H8) and Butane (C4H10).
- In some regions, it may contain smaller proportions of Propylene or Butylene depending on the production process and the specific market standards.
- LPG is a fossil fuel byproduct obtained during the refining of petroleum or extracted from natural gas streams.
Key Characteristics
- State: Under normal atmospheric pressure, these gases exist as vapors; however, they are stored as liquids under moderate pressure in steel cylinders to reduce volume.
- Odorization: Because LPG is naturally odorless, Ethyl Mercaptan is added as an odorant to ensure leaks can be detected by smell, serving as a critical safety measure against fire and explosion hazards.
- Combustion: It is a high-calorific value fuel that burns cleanly, producing fewer particulates and lower levels of carbon monoxide compared to traditional solid fuels.
- Density: LPG vapor is heavier than air, meaning that in the event of a leak, it tends to accumulate in low-lying areas or floor-level crevices, which is a vital factor in fire hazard mitigation and ventilation design.
