Anti-surge recycle for centrifugal compressors in NeqSim: chart generation, AntiSurgeRecycleCalculator, dynamic AntiSurgeController, CompressorAntiSurgeApplication binding, MinimumSpeedRecycleControllerStructure split-range control, speed-solve convergence and recycle power/CO2 savings. USE WHEN: a task must protect a compressor from surge with a recycle loop, coordinate speed and recycle at minimum speed, or value avoided recycle.
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
# Compressor Anti-Surge Recycle Setup This skill explains how to protect a centrifugal compressor against surge in a NeqSim `ProcessSystem` by adding a recycle (spill-back) loop. It covers the preferred steady-state helper (`AntiSurgeRecycleCalculator`), the dynamic reverse-acting PI controller (`AntiSurgeController`), and the application-level supervisor (`CompressorAntiSurgeApplication`) that can bind directly to real NeqSim topology objects such as a compressor, hot recycle valve, cold recycle valve, cooler, mixer, recycle blocks, and `ProcessSystem`. It also explains how to **auto-generate a compressor chart with surge and stonewall curves** when no vendor chart is available, because every anti-surge option needs a surge limit to act against. The pure-Python helper (`AntiSurgeRecycleModel`) is an educational planning aid that mirrors NeqSim's proportional anti-surge step so an agent can pre-estimate the recycle flow and decide whether a chart must be generated first. Real control design must use the validated NeqSim equipment classes below and a qualified rotating-equipment review (API 617 / API 692). ## Complete compressor automation and P&ID studies …

How to install
mdr add equinor/neqsim/neqsim-compressor-antisurge-recycle@sha256:a1f4e5306ebcff30The line at the top of this page pins the label v0.5.0, 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.
