|European Commission - EurostatInternational Energy Agency (IEA)Petroleum refineries are industrial plants which convert (transform) crude oil and other hydrocarbons into finished petroleum products.International Energy Forum Secretariat (IEFS)In this flow, the quantities of crude oil inputs entering the refinery should be reported. Although there are several other inputs to refineries e.g. Natural Gas Liquids (NGL), refinery feedstocks, additives, biofuels and other hydrocarbons, currently the questionnaire is not collecting any details of any other inputs than crude oil.
Please also note that the volume of crude oil reported as refinery intake should reflect the real quantities of inputs to the refinery process and not the deliveries of crude oil to the refinery. The difference between the two measures is the stock changes of crude oil at the refinery.Latin American Energy Organization (OLADE)A center where oil is transformed into derivatives. Refineries basically separate crude oil into its different components. This methodology will treat all refineries as if they were a single processing unit. Although this representation does not allow you to completely describe the transformation center in terms of refining, or analyze the internal flexibility of each refinery, it suffices to establish the input and output ratios for the balance that proposed herein. There are different types of refineries with different types of processes, which do not always obtain the same products.Organisation of Petroleum Exporting Countries (OPEC)Petroleum Refineries shows the use of primary energy in refineries and the output of petroleum products. Thus, the total reflects the refineriesí own use of all fuels, as well as any losses.United Nations Economic Commission for Europe (UNECE)Petroleum refineries are industrial plants which convert (transform) crude oil and other hydrocarbons into finished petroleum products.
