Description: technologyComment of natural gas liquids fractionation (GLO): The recovered NGL stream is processed through a fractionation train consisting of up to five distillation towers in series: a demethanizer, a deethanizer, a depropanizer, a debutanizer and a butane splitter. The overhead product from the deethanizer is ethane and the bottom product is fed to the depropanizer. The overhead product from the depropanizer is propane and the bottom is fed to the debutanizer. The overhead product from the debutanizer is a mixture of normal and iso-butane, and the bottom is a C5+ gasoline mixture (pentane in this inventory). A slightly simplyfied fractioning process can be seen in the sketch below. imageUrlTagReplace937d93d2-cfed-4ec9-9363-614415661a5c Source: Thompson S. M., Robertson G. (2011): Liquefied Petroleum Gas, in Ullmanns Encyclopedia of Industrial Chemistry, 7th Edition. technologyComment of natural gas production (CA-AB): Canadian data completed with german data. The uncertainty has been adjusted accordingly. Data used in original data contains no information on technology. technologyComment of natural gas production (RoW): The data describes an average onshore technology for natural gas to 13% out of combined oil gas production. Natural gas is assumed to 20% sour. Leakage in exploitation is estimated at 0.38% and production 0.12%. It is further assumed that about 30% of the produced water is discharged in surface water. Water emissions are differentiated between combined oil and gas production and gas production.

Comment: This is a market activity. Each market represents the consumption mix of a product in a given geography, connecting suppliers with consumers of the same product in the same geographical area. Markets group the producers and also the imports of the product (if relevant) within the same geographical area. They also account for transport to the consumer and for the losses during that process, when relevant. This is the market for 'propane', in the Global geography. Transport from producers to consumers of this product in the geography covered by the market is included. propane' is an organic substance with a CAS no. : 74-98-6. It is called 'propane' under IUPAC naming and its molecular formula is: C3H8. It is a gas under normal conditions of temperature and pressure with no distinct odour. It is modelled as a pure substance. On a consumer level, is used in the following products: anti-freeze products, adhesives and sealants, polishes and waxes, washing & cleaning products, air care products, cosmetics and personal care products, fuels and adsorbents. On industrial sites, the substance is used for the manufacture of products in the following sectors: fuels and chemicals. If used as a fuel, it has a calorific value of 46.40 MJ/kg and is a fossil fuel, sourced from extraction from natural gas. This market is supplied by the following activities with the given share: natural gas production, CA-AB: 2.09597120647708e-05 natural gas production, RoW: 2.32301351563739e-05 natural gas liquids fractionation, GLO: 0.999955810152779 generalComment of natural gas liquids fractionation (GLO): This dataset represents the fractioning of natural gas liquids (NGL) to yield in ethane, propane, butane and pentane. NGL consists of 38% ethane, 33% propane, 18% butane and 11% pentane, the composition was approximated by using the yearly US field production (https://www.eia.gov/dnav/pet/pet_sum_snd_d_nus_mbbl_m_cur.htm). [This dataset is meant to replace the following datasets: - propane extraction, from liquefied petroleum gas, GLO, 2005 - 2005 (9a114126-73b2-439f-be49-9baf778457fc) - pentane extraction, from natural gas liquids, GLO, 2008 - 2008 (ca68ff46-5aa8-426e-a5f9-93933263af14) - ethane extraction, from natural gas liquids, GLO, 2008 - 2008 (6c470c8d-51d2-4931-9e4b-8c293d138897) - butane extraction, from natural gas liquids, GLO, 2008 - 2008 (c8e7ce5f-3942-4692-8c83-aad2382b5592)] generalComment of natural gas production (RoW): Data for RU is mostly based on standard data, as only few information on the Russian production is available. [This dataset was already contained in the ecoinvent database version 2. It was not individually updated during the transfer to ecoinvent version 3. Life Cycle Impact Assessment results may still have changed, as they are affected by changes in the supply chain, i.e. in other datasets. This dataset was generated following the ecoinvent quality guidelines for version 2. It may have been subject to central changes described in the ecoinvent version 3 change report (http://www.ecoinvent.org/database/ecoinvent-version-3/reports-of-changes/), and the results of the central updates were reviewed extensively. The changes added e.g. consistent water flows and other information throughout the database. The documentation of this dataset can be found in the ecoinvent reports of version 2, which are still available via the ecoinvent website. The change report linked above covers all central changes that were made during the conversion process.] generalComment of natural gas production (CA-AB): This dataset represents the production of natural gas on-shore in Alberta (Canada) in 2010. Some flows have been adapted using local data, namely, the emissions to air of greenhouse gases (CO2, CH4, N2O), the criteria air contaminants (PM2.5, CO, non-methane VOC, NOx, SO2) and the hydrogen sulfide. Local data have also been used for the percentage of sour and sweet gas and the quantities of flared, vented and burned in turbine gas, quantity of sulfur extracted by sweetening and production volumes. Sweetening and drying processes have been included in the process.Sulfur production associated with the desulfurisation process has been included.The sweetening process, included in the dataset, delivers sweet gas (natural gas, propane), sulfur and other gases (ethene, butane, pentane). This dataset is an adaptation of the dataset describing the average extraction onshore in Germany in 1996-2000 period and the drying and sweetening datasets from the ecoinvent 2.0 database. [This is a dataset transferred from ecoSpold v1 / ecoinvent database version 2. It may not in all aspects fulfill the requirements of the ecoinvent data quality guideline for version 3.]
