Exchanges per 1 kilogram of Liquid phosgene to the captive consumer

As exported: allocated and scaled to the reference product. Provenance: 8 assumed, 5 calculated. Pedigree scores (1 best, 5 worst): reliability, completeness, temporal correlation, geographical correlation, further technological correlation.

Preliminary2 exchanges are not yet linked to a background dataset. They count no burden, so the inventory is incomplete: do not read a result from it as complete.

The streams are the plant's own flows: an amount here is allocated and per 1 kilogram of Liquid phosgene to the captive consumer, so it differs from the stream's flow, and it can sum several streams.

Where these numbers come from: each exchange names its source above; the dataset is processes/phosgene-1/lca/dataset.yaml in library version c3ab348.

How to use it

Downloads

A file with this activity alone is not available: each file above is the whole database, and the line under it says how to find this activity there.

import bw2data as bd
from cheme_as_code_lci import install

bd.projects.set_current("my-project")   # holds your licensed background + biosphere3
install("cheme-as-code-atlas-preview-c3ab348.xlsx", background="ecoinvent-3.11-cutoff", location="DE")
activity = bd.get_activity(("cheme-as-code-atlas-preview-c3ab348", "phosgene-1:phosgene-from-co-and-chlorine-over-activated-carbon-17.3-t-h-liquid-phosgene-captive:product:PHOSGENE"))

While any exchange of the database has no mapping, install() writes nothing and only lists the unlinked exchanges. So the last line finds no activity until the gaps are mapped: the download section gives the ways to use the database now.
