Description: technologyComment of ethyl benzene production (RER): Production by alkylation of benzene with ethylene with a yield of 97%. Inventory bases on stoechiometric calculations. The emissions to air (0.2 wt.% of raw material input) and water were estimated using mass balance. Treatment of the waste water in a internal waste water treatment plant assumed (elimination efficiency of 90% for C).

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 dataset represents the supply of 1 kg of ethyl benzene from activities that produce it within the geography RER. A regional market for Europe [RER] is motivated by the low share (in the range of 0.0%-9.8% of total trade quantities between 2010-2016) of import quantities to EU28 from outside (excluding Norway and Switzerland) the Union. Source: Eurostat database, EU trade since 1988 by HS6 (DS-016893), HS6-code: 290260 - ETHYLBENZENE, Assessed on: 2017-11-28. The transport amounts are based on eurostat transport statistics for 2016 (http://ec.europa.eu/eurostat/data/database, extracted on the 2018-06-01). See exchange comments for additional details. This market is supplied by the following activities with the given share: ethyl benzene production, RER: 1.0 generalComment of ethyl benzene production (RER): The functional unit represent 1 kg of liquid ethylbenzene. Large uncertainty of the process data due to weak data on the production process and missing data on process emissions. [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.]
