| Use advice for data set | Notice: this data set supersedes the EF3.0-compliant version (see link under "preceding data set version" below calculated with the EF3.0). The life cycle inventory is not changed from the original EF3.0 data set. The LCIA results are calculated based on the EF3.1 methods which provide updated characterisation factors in the following impact categories: Climate Change, Ecotoxicity freshwater, Photochemical Ozone Formation, Acidification, Human Toxicity non-cancer, and Human Toxicity cancer. The review report and the data quality ratings refer to the original results. The data set has been updated by the European Commission on the basis of the original EF3.0 data set delivered by the data provider. Life Cycle Inventory (LCI) dataset to be used for implementing regular Product Environmental Footprint (PEF) studies and Organisation Environmental Footprint (OEF) studies. This dataset has been developed by an industry association and has not been officially tendered by EC. The datasets are specifically designed for these methodological requirements (see above) and the related LCIA methods (listed below) recommended in EF. |

| General comment on data set | The data set covers all relevant process steps / technologies over the supply chain of the represented cradle to gate inventory with a very good overall data quality. The inventory is based on representative industry data collected for OSPA (Oxygenated Solvent Producers Association) and the following member companies: BASF SE, Germany; Eastman Chemical Company, USA; INEOS Oxide, Switzerland; Sasol Germany GmbH, Germany. This primary data is completed by secondary background datasets. |

| Technology description including background system | Foreground system: Ethylene glycol butyl ether (EGBE), also called 2-Butoxyethanol, is a colourless liquid and one of the simplest glycol monoalkyl ethers. Ethylene glycol mono alkyl ethers are not manufactured as pure compounds but must be separated from the diethers and higher glycols. There are two common methods of producing ethylene glycol butyl ether: reaction of ethylene oxide with anhydrous butyl alcohol in the presence of a catalyst and direct alkylation of ethylene chlorohydrin or ethylene glycol using sodium hydroxide and an alkylating agent such as dibutyl sulfate. By far the dominant method of ethylene glycol butyl ether production is treatment of butyl alcohol with ethylene oxide. Depending on the molar ratios of the raw materials (the ratio of ethylene oxide to n-butanol greater than one initiates the production of di- and tri-ethylene glycol monoethers along with the EGBE), varying amounts the monoethylene, diethylene, triethylene and higher glycol ethers are obtained. Thus, the further treatment is the separation and purification by fractional distillation to obtain the desired product. Transports and process waste treatment are included in this dataset. Background system: Electricity: Electricity is modelled according to the individual country-specific situations. The country-specific modelling is achieved on multiple levels. Firstly, individual energy carrier specific power plants and plants for renewable energy sources are modelled according to the current national electricity grid mix. Modelling the electricity consumption mix includes transmission / distribution losses and the own use by energy producers (own consumption of power plants and "other" own consumption e.g. due to pumped storage hydro power etc.), as well as imported electricity. Secondly, the national emission and efficiency standards of the power plants are modelled as well as the share of electricity plants and combined heat and power plants (CHP). Thirdly, the country-specific energy carrier supply (share of imports and / or domestic supply) including the country-specific energy carrier properties (e.g. element and energy content) are accounted for. Fourthly, the exploration, mining/production, processing and transport processes of the energy carrier supply chains are modelled according to the specific situation of each electricity producing country. The different production and processing techniques (emissions and efficiencies) in the different energy producing countries are considered, e.g. different crude oil production technologies or different flaring rates at the oil platforms. Thermal energy, process steam: The thermal energy and process steam supply is modelled according to the individual country-specific situation with regard to emission standards and considered energy carriers. The thermal energy and process steam are produced at heat plants. Efficiencies for thermal energy production are by definition 100% in relation to the corresponding energy carrier input. For process steam the efficiency ranges from 85%, 90% to 95%. The energy carriers used for the generation of thermal energy and process steam are modelled according to the specific import situation (see electricity above). Transports: All relevant and known transport processes are included. Ocean-going and inland ship transport as well as rail, truck and pipeline transport of bulk commodities are considered. Energy carriers: The energy carriers are modelled according to the specific supply situation (see electricity above). Refinery products: Diesel fuel, gasoline, technical gases, fuel oils, lubricants and residues such as bitumen are modelled with a parameterised country-specific refinery model. The refinery model represents the current national standard in refining techniques (e.g. emission level, internal energy consumption, etc.) as well as the individual country-specific product output spectrum, which can be quite different from country to country. The supply of crude oil is modelled, again, according to the country-specific situation with the respective properties of the resources. |
