Liquefied Petroleum Gas (LPG or LP Gas) refers to a mixture of hydrocarbon gases with compounds containing primarily propane (C3) and butane (C4). Although these gases are in vapour form, they are compressible to transportable liquid. They can be liquefied through a compression process at ambient temperature, refrigeration at atmospheric pressure, or a combination of both. The pressure required to liquefy the vapour is relatively low, allowing easy storage of the liquid gas in pressurised vessels at ambient temperature. LPG returns to vapour form when the pressure is released.
LPG is most commonly traded as a mixture of propane and butane. The ratio of the mixture typically varies depending on the climate - the cooler the climate, the higher the propane content. As a precaution, a powerful odorant (Ethyl Mercaptan) is added in small amounts to make gas leaks easily detectable as LPG is highly flammable, odourless and colourless.
LPG is extracted both during natural gas production and crude oil refinery processing.
Natural gas may contain up to 10% of propane and/or butane, which is removed for technical, commercial and safety reasons. Crude oil refining typically produces around 2% to 4% of propane and/or butane
Historically, LPG – essentially a by-product – was very often flared. However, the increased value of and demand for LPG, coupled with the undesirable environmental impact of flaring, have justified the significant investment in the storage and distribution of LPG.
Deepetro is in the business of trading and transporting Liquefied Petroleum Gas (LPG). We are focused on expanding LPG markets in the international markets while aiming to provide superior service and reliability. Our aim is to assist developing countries in the transition from non-renewable energy sources to sustainable energy.
