Reaction engineering patterns for NeqSim. USE WHEN: modeling chemical reactors (equilibrium, kinetic, CSTR, PFR), setting up reaction systems, analyzing conversion/selectivity, or designing reactor networks. Covers GibbsReactor (equilibrium), PlugFlowReactor (kinetic PFR), StirredTankReactor (CSTR), KineticReaction setup, and CatalystBed configuration.
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
# Reaction Engineering Patterns Guide for chemical reactor modeling in NeqSim using the reactor equipment classes. ## Reactor Type Selection | Reactor Type | NeqSim Class | When to Use | |-------------|-------------|-------------| | Equilibrium | `GibbsReactor` | High-T reactions approaching equilibrium (reforming, combustion, water-gas shift) | | Plug Flow (PFR) | `PlugFlowReactor` | Tubular reactors with axial kinetics, catalytic fixed beds | | Stirred Tank (CSTR) | `StirredTankReactor` | Perfectly mixed, steady-state with kinetics | | Stoichiometric | `StoichiometricReaction` | Known fixed conversion, simple mass balance | | CO2-specific equilibrium | `GibbsReactorCO2` | CO2 capture reactions with optimized convergence | | Fermenter | `Fermenter` | Bio-reactions, enzymatic processes | ## Equilibrium Reactor (GibbsReactor) Best for high-temperature reactions where equilibrium is reached. ### Setup Pattern ```java import neqsim.process.equipment.reactor.GibbsReactor; import neqsim.process.equipment.stream.Stream; import neqsim.thermo.system.SystemSrkEos; // Create feed fluid with reactants SystemInterface fluid = new SystemSrkEos(273.15 + 800.0, 30.0); …

How to install
mdr add equinor/neqsim/neqsim-reaction-engineering@sha256:15b152fe7aad80dfThe line at the top of this page pins the label git:20260807.b113af9, 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.
