Liquefied petroleum gas (LPG) is the generic name for commercial propane and commercial butane. It can be produced from natural gas processing plants, oil refineries and in natural gas liquefaction plants as a byproduct of the production of liquefied natural gas (LNG).
When crude oil and natural gas are produced from the well (either from associated or non-associated wells), they are a mixture of oil, water, sediment and dissolved gases (methane, ethane, propane, butane and pentanes). In the first instance, all gases are separated from the oil/gas mixture in natural gas processing plants and separation plants.
The gases are extracted because of their higher value and their readily marketable state, such as propane and butane which are LPG. In a later stage, the sediment and other unwanted substances are removed in treatment plants.
The gases are separated in a wellhead separation plant from onshore and offshore wells respectively. This happens through a separator on the platform. The methane will form the constituent of natural gas, while the others form the Natural gas liquids (NGL). Natural gas liquids however can also be produced in conjunction with natural gas.
In the JODI format, quantities of indigenous NGL which are not included in Refinery intake, such as the amounts going to a gas plant, should be reported as Receipts of Other products, and then transferred through the Inter-product transfers line to the allocated product type.
