Cumene by zeolite alkylation of benzene with propylene
Tier 0 screening per tonne of cumene: stoichiometry with a licensor's benzene figure and net steam, US EPA facility air emissions, electricity from core's default. No flowsheet; not reviewed.
Research outputNot engineering advice and not an approved design: do not use it for construction, operation or safety decisions. What this means
Overview
- Capacity
- per tonne of cumene (the dataset's basis); no plant size
What goes in and out
Utilities: Electricity (core's Tier 0 default (ASSUMED, dated)), Steam (net of LP export, so it embeds a credit for exported steam (deviation in the dataset); pressure not stated by the source)
Life cycle assessment
No footprint assessed yet; the process is part of the life-cycle inventory below.
In the open LCI database (cheme-as-code-atlas-preview-c3ab348) as Cumene, 99.95 wt% Preliminary.

In the LCI database: system model, datasets and KPIs against the benchmarks
In the LCI database
- Status
- Preliminary 4 unmapped exchanges. Some exchanges have no background mapping yet: they are exported unlinked and count no burden, so the inventory is incomplete.
- System model
- attributional, cut-off (methodology 1.1.0)
- Allocation
- mass (single-output, from default) · product:cumene 100 %
- Allocation findings
- none
- Change report
- Not available: this build has no change report against an earlier release.

Maturity and review
Design maturity Concept (claimed): An idea or first flowsheet; numbers are rough. No independent engineering review yet. Automated checks passing is not a review.
Calculation maturity, from the checked evidenceNot assessed
The process has no maturity report (cheme maturity, checks/maturity.json), so no calculation maturity is established.
No level shownThe design maturity (Concept) is the manifest's claim, not evidence. A level appears here once the process's repository holds a current report from
cheme maturity --write.Artifact completeness
Which deliverables exist. They never raise a calculation maturity level: a drawing from unchecked numbers is still unchecked.
Not reported without a maturity report.
Independent review
Not independently reviewed
No independent engineering review yet. Automated checks passing is not a review.
Set by people only. Reaching a calculation maturity level or passing automated checks is not an independent review or an approval.
