neqsim-refinery-crude-processing SKILL.md skillA

neqsim-refinery-crude-processing from equinor/neqsim is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add equinor/neqsim/neqsim-refinery-crude-processing@git:20261021.d11a64b

Pins git:20261021.d11a64b in mdr.lock. Pin the fingerprint instead.

NeqSim refinery assay, crude blending, fractionation, ASTM D86, hydrotreating, and catalytic-reforming workflows. Covers OilAssayCharacterisation, RefineryAssayBlend, RefineryLinearBlendOptimizer, hydrotreating receipts, RefineryCatalyticReformingStoichiometricBalance, and Standard_ASTM_D86. USE WHEN: characterizing assays, blending feeds, screening contaminant removal or reforming stoichiometry, estimating hydrogen, utility, or economics receipts, or comparing fractionation products.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Refinery Crude Processing

## When to use this

Use this skill for NeqSim's existing crude-assay, petroleum-cut, refinery blend, crude-fractionation reference-case, product-boiling-range, hydrotreating balance, and catalytic-reforming stoichiometric APIs. Treat the APIs as connected building blocks, not as one turnkey refinery simulator.

The useful data flow is:

`assay data -> OilAssayCharacterisation -> pseudo-component fluid -> blend plan/batch -> equilibrium column, hydrotreating balances, or reforming stoichiometry -> operating/economics receipts`

Use `neqsim-distillation-design` for equilibrium-column setup and convergence details. Use `neqsim-eos-regression` when the job is to fit an EOS to measured PVT rather than convert an assay. The Doe Big Hill and Sarir classes are case-specific reference scenarios; reuse their construction pattern with a user-provided assay and operating basis instead of treating their constants as a general crude-unit design.

How to install

The exact contents, by fingerprint
mdr add equinor/neqsim/neqsim-refinery-crude-processing@sha256:d7b48643c1689064

The line at the top of this page pins the label git:20261021.d11a64b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
