Liquefied Petroleum Gas (LPG or LP Gas) refers to a gaseous hydrocarbon mix of compounds containing primarily propane (C3) and butane (C4). OPL imports 30% Propane & 70% Butane LPG Mix.
The gases are compressed to liquid form for better transportability. The liquefied state can be achieved through processing at ambient temperature, refrigeration at atmospheric pressure, or a combination of both. Although, the pressure required to liquefy the vapor is relatively low, allowing easy storage of the liquid gas in pressurized vessels at ambient temperature. When released, the LPG reverts back to its gaseous state.
Since LPG is an odourless & colourless substance, a potent odorant (Ethyl Mercaptan) is added in a small amount for easier detectability.
LPG is extracted during natural gas production and crude oil refinery processing. Natural gas likely contains up to 10% of propane and/or butane, which is discarded for technical, commercial and safety reasons. Crude oil refining, on the other hand, typically produces around 2% to 4% of propane and/or butane.
LPG – essentially a by-product – was very often flared in the past. However, the increasing value and demand for LPG, coupled with its environmental and social impact, have justified the significant investment in the storage and distribution of LPG.
LPG is a clean and efficient fuel that emits 20% less carbon dioxide (CO2) than heating oil, 50% less CO2 than coal and 70% less CO2 than wood. LPG makes cooking, heating and generating electricity an environmentally friendly process.
LPG has achieved growing popularity and demand due to its versatility and environment-friendliness. It is being explored widely as the handiest form of modern energy source. In larger scale, it is widely used in the commercial and residential sector as a fuel for heating and cooking solutions.
Applications of LPG can also be found in various sectors including industrial, commercial, agricultural and transportation.
