Butene - mixed (butadiene purification - extractive distillation of C4 hydrocarbon mixture)

The activity generating the emissions is butadiene purification, extractive distillation of C4 hydrocarbon mixture. The Reference Product is butene, mixed. Butene, mixed is a fossil fuel with a calorific value of 45.3 MJ/kg. It is gaseous at standard conditions, but often liquefied for its use as a fuel, and is sourced from steam cracking of naphtha followed by fractional distillation or ethylene dimerisation. Its main applications are in the following sectors: gasoline additive and polymer production. The Reference Product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary transforming activity. Please refer to the ecoinvent documentation for full details: https://ecoquery.ecoinvent.org/3.12/cutoff/dataset/275606/documentation
