stages-thermo 0.0.1

Staged-separation (distillation) column solver: McCabe–Thiele, Ponchon–Savarit, FUG shortcut, and rigorous MESH methods, built on vle-thermo

stages-thermo

A staged-separation (distillation) learning library and fast steady-state column solver, built on vle-thermo.

import stages — walk the full pedagogical ladder of column methods (McCabe–Thiele → Ponchon–Savarit → Fenske–Underwood–Gilliland shortcut → rigorous MESH), each implemented from scratch and anchored to its textbook equations, with a granular, batch-capable API ("numpy for distillation columns"). All thermodynamics come from vle-thermo; this package adds none of its own.

pip install stages-thermo      # import name is `stages`

Status: 0.0.x is a name-holding stub (Milestone 0, repo bootstrap). The only surface today is the vle-thermo smoke path. Column methods land milestone by milestone — see the repo's ROADMAP.md. Not usable for real work until 1.0.

import stages

stages.__version__
# '0.0.1'

# M0 smoke path: equimolar methanol/water bubble T [K] at 101.325 kPa, computed
# through vle-thermo. Approximate — proves the dependency links end-to-end,
# not a validated value.
stages.smoke_bubble_temperature()

The native core is a Rust crate (stages-thermo on crates.io) with PyO3 bindings; wheels are abi3 (cp310-abi3-*), so one wheel per (OS, arch) covers CPython 3.10+.
