General comment [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.]
The functional unit represent 1 kg of liquid acrylic acid. Large uncertainty of the process data due to weak data on the production process and missing data on process emissions.
Production volume: 1.32236940655721 kg
Included activities end: Raw materials and chemicals used for production, transport of materials to manufacturing plant, emissions to air and water from production, estimation of energy demand and infrastructure of the plant (approximation). Solid wastes omitted.
Energy values: Undefined (default)
Geography: Data used has no specific geographical origin (stoechiometry). Average europenan processes for raw materials, transport requirements and electricity mix used.
Technology level: 3 Current (default)
Technology: Production from propylene by two-step oxidation process with a process yield of 90%. Inventory bases on an two general reports about the theoretical production of acrylic acid.
