Liquefied petroleum gases include Ethane (C₂H₆), butane (C₄H₁₀), Isobutane (i-C₄H₁₀), Propylene (Propene), Ethylene, Butylene (Butene), and various mixtures of hydrocarbons.

These gases are called Liquefied Petroleum Gas (LP-gas or LPG). LPG is used for:

1. Fuel for space heaters, water heaters, boilers, cooking, grilling, air conditioners (AC), and cooling in both rural and urban areas beyond gas pipeline coverage.
2. Backup fuel supply for large-scale industrial utilities (especially those using furnaces or ovens requiring constant temperature control) to safeguard against interruptions in natural or synthetic gas supply.
3. Space heating during building construction (pile-driving).
4. Fuel for entire industrial heating processes, especially where precise temperature control is required.
5. Fuel for processes such as poultry farming, cotton and grain drying, tobacco curing, food drying, burning grass, and greenhouse heating.
6. Vehicle fuel for trucks, buses, taxis, transport vehicles, and agricultural machinery like tractors and harvesters.
