OpenFlowsheet v0.3.0

Draft (V03 WO-4); nothing below is released. The release candidate C, its gate table and the
verdicts are added to this section at C (V03 spec §4, ADR 0053). 0.3.0 claims V11–V20, W21–W26
and X31; W27 is not claimed.

S01 — the countercurrent equilibrium-stage subsystem

• Equilibrium stages with explicit degrees of freedom and energy and phase coupling, an
  initializer and Newton continuation, on SYN-001. Manifest
  evidence/S01/465240a4…/manifest.json.

S02 — the MESH column

• Stage indexing, feed, condenser, reboiler, pressure and specification conventions; four matched
  cases and the invalid-specification and invalid-phase refusals. Manifest
  evidence/S02/1810dde8…/manifest.json.

S03 — independent column references

• Column answers compared with an independently written implementation across the available suite,
  with perturbation studies and the supported nonideal scope. Manifest
  evidence/S03/930aad1b…/manifest.json.

S04 — the Peng–Robinson component library pr-lib-v1 (library-only)

• A vapour-phase Peng–Robinson library provider; a revision cannot select it, and its records do
  not ship. Manifest evidence/S04/5c29fbf6…/manifest.json.

S05 — IAPWS-95 water iapws95-v1

• The IAPWS-95 formulation as a provider with its own reference convention IAPWS95-ref-v1; the
  coefficients ship with IAPWS's attribution in NOTICE. Manifest
  evidence/S05/01cdeed4…/manifest.json.

S06 — column specifications by purity, recovery and stage temperature

• Purity, recovery and stage-temperature specifications for the column, with their rows, degrees of
  freedom and typed refusals. Manifest evidence/S06/ad264a23…/manifest.json.

S07 — CoolProp pure fluids coolprop-heos-v1 (optional extra coolprop)

• CoolProp 8.0.0's Helmholtz equations of state for 123 fluids in two tiers, reference convention
  COOLPROP-DEF-ref-v1, compared across architectures within registered bounds (ADR 0046).
  Manifest evidence/S07/7bfab70d…/manifest.json.

S08 and S08b — one-phase column sections and the phase contract

• Block openings for column sections in one phase (ADR 0048), and signature items by declaration
  with saturation consistency for S01 cascades. Manifests evidence/S08/6d7d1a6d…/manifest.json
  and evidence/S08b/acbd1266…/manifest.json.

S09 — BioSTEAM as a third column reference

• A blind third reference for the column cases: 19 of 19 qualified, X31 met where available for 3
  of 4 cases. Manifest evidence/S09/4d4df087…/manifest.json.

S10 and S10-C — the Wilson liquid-mixture method on real records

• wilson-ig-v1: Wilson activity coefficients with an ideal-gas vapour for methanol, ethanol and
  water, Wilson parameters fitted to published equilibrium data (Kurihara et al. 1993), with the VAL-1–3
  validation bands (ADR 0047); S10-C adds the
  γ–φ PH flash and the column on Wilson (ADR 0049). Wilson's records and the Kurihara 1993 points
  ship as package data (V03 spec §9.1). Manifests evidence/S10/f6f27c3f…/manifest.json and
  evidence/S10c/2aedd250…/manifest.json.

S11 — the binding package

• Water (IAPWS-95), CoolProp's pure fluids and Wilson selectable in flowsheets; the seven
  thermal.* units; the column as a flowsheet unit (ADRs 0050, 0051). semantic_role gains
  compressor, turbine and other (ADR 0054). Manifest evidence/S11/01e72ca4…/manifest.json.

S12 (E01) — cost estimation and LCA

• Cost and life-cycle impact as differentiable post-solve functionals of a
  verified state, with an accuracy class (ADR 0052); the LCA table builder needs the optional
  extra lca. Manifest evidence/S12/02fc8d2f…/manifest.json.

What it is not

• numerical verification, not empirical validation
• no global optimality
• Linux only
• not a sandbox
• the stand-in reactor is synthetic
• no reactor result has been compared with experimental data by this project: the group's published
  comparison is the group's evidence, and every real-reactor number is the group's model at the pin,
  a regression, whose discretization bias is 1.0–1.4 % in NH₃ (M02 design note §13)
• the optimization routes need the optional nlp extra
• the CoolProp provider needs the optional coolprop extra
• cost and LCA results are assessment estimates with an accuracy class
• cost and LCA are Python-only
• no ecoinvent data
• Wilson is vapour-liquid only; no liquid-liquid split
• no automatic liquid/vapour regime switching for pure fluids
• X31: one independent reference for the refluxed absorber
• no rate-based column models
• no W27 claim in 0.3.0
• no CFD or Peclet refinement
• no external benchmark score
