Carbon dioxide, dense phase, >= 99.95 mol%, 153 bara

What it is

Per 1 t of dense-phase CO2 at 15.3 MPa and 30 degC (99.95 mol% CO2), gate-to-gate, from the wet stripper vent of a natural-gas ammonia plant. Compression, drying and cooling only; the CO2 separation belongs to the ammonia plant, and the vent gas enters without burden (system-model section 2, step 4). After the NETL ammonia case of 2023.

Database

cheme-as-code-atlas-preview-a3c52e4 (version preview-a3c52e4)

Process

CO2 conditioning of a high-purity source (ammonia CO2 stripper vent), compression and TEG drying

Geography

US · background inputs with a site rule link at the user's site location (default DE)

Time period

2018 · valid until 2028

Technology

reciprocating CO2 compression to 15.3 MPa with triethylene glycol dehydration and an evaporative cooling tower; no CO2 separation (the source is already 97 mol% CO2) · level current

Boundary

gate-to-gate: inlet water knockout, five-stage reciprocating compression with intercooling, TEG drying within the train, aftercooling, and a stand-alone cooling-water system; from the stripper vent outlet to the pipeline inlet (IPCC 2006 V2 5.3: capture includes compression and dehydration)

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-a3c52e4.xlsx", background="ecoinvent-3.11-cutoff", location="DE")
activity = bd.get_activity(("cheme-as-code-atlas-preview-a3c52e4", "carbon-capture-1:co2-conditioning-ammonia-stripper-vent:product:CO2"))

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.
