Processforge
A lightweight Python framework for process simulation, coupling hydraulic, thermal, and reactor workflows.
Install
uv add processforge
For CoolProp-backed units:
uv add "processforge[coolprop]"
Optional solver backends:
uv add "processforge[eo]"
uv add "processforge[eo-casadi]"
uv add "processforge[modelica]"
Quick start
Use plan to validate and preview changes, then apply to solve and store a snapshot. For flowsheets without Tank units, use apply to solve with the EO solver.
pf init
pf plan flowsheets/hydraulic-chain.json
pf apply flowsheets/hydraulic-chain.json
For flowsheets with Tank units, use run to solve with the SM solver. For direct run mode (for dynamic flowsheets with Tank units), use run:
pf run flowsheets/hydraulic-chain.json
Python API
from processforge import EOFlowsheet, validate_flowsheet
config = validate_flowsheet("flowsheets/hydraulic-chain.json")
fs = EOFlowsheet(config, backend="scipy")
results = fs.run()
Usage and Docker
Processforge is also available as Docker images, and can be run in the cloud. See the usage guide for CLI commands, workflows, Docker, and cloud notes.
Flowsheets
The core of Processforge is the flowsheet JSON format, which defines materials, units, and recycle rules. See below for more information on the formats and example flowsheets.
