Run one fluid (E300 or composition) through a forward-only, no-recycle separator train (HP, MP, LP, stock tank) like PVTsim/ECL300 and return GOR, Bo, STO API and gas per stage; also fit ONE shared stage P/T set to reservoir-simulation oil and gas rates over many fluids. USE WHEN: 'kjør dette for et gitt fluid', surface GOR/Bo/STO for an E300 fluid, or fitting the pseudo-process P/T per tank/scrubber of a reservoir simulation.
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
# Forward Separator Train for One Fluid
A forward train has no recycle: liquid cascades from stage to stage and every gas
stream leaves the system. For a fixed composition and fixed stage pressures and
temperatures the result is therefore unique and needs no iteration. This is the
same separator test PVTsim and ECL300 run, so results can be compared directly.
The skill runs **one** fluid. To study variation, call it once per fluid
(see "Many fluids" below).
## When to Use
- A fluid is given as an E300 file (or a mole-fraction table) and surface results are needed.
- GOR, Bo, stock-tank oil density/API, or gas rate and gas MW per stage are requested.
- A PVTsim or ECL300 separator-test number must be reproduced or sanity-checked.
Do not use it for trains with recycles or with feedback from compressors or
coolers into earlier stages; build a `ProcessSystem` with recycles instead.
## Inputs
| Input | Default | Notes |
| --- | --- | --- |
| E300 file or `--composition` JSON | required | Exactly one. JSON: `{"eos":"srk","components":{"methane":0.7,...}}` (`srk` or `pr`, library component names). |
| `--feed-p` | 250 bara | Set to reservoir (or wellstream) pressure. |

How to install
mdr add equinor/neqsim/neqsim-forward-separator-train@sha256:66149edb78dc4659The line at the top of this page pins the label v0.1.0, 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.
