ProcessChem Documentation

About

ProcessChem is a chemical process engineering calculator. This is its documentation. The icon beside each tab heading, and beside the Thermo mode and Case dropdowns, opens the matching page here in your browser; the ⓘ beside a value in the app opens a short note on where that value came from.

Every page follows the same shape: About first, then the inputs, what comes back, and the physics behind it.

Tabs

• Property — look up one chemical or mixture's properties at a temperature and pressure
• Thermo — four ways of asking what happens to a substance
• Case — real-world scenarios, each with its own inputs
• Units — per-quantity unit choice and the Normal-flow reference

Keeping your work

• Saving and opening — what Open and Save keep, and how to save a case to a file that survives deleting the app

Thermo modes

• Phase Equilibrium — one chemical changing state
• Chemical Equilibrium — a feed left to find its own minimum
• Reaction — a reaction you already know
• Electrochemical Reaction — a reaction driven by electricity, or driving it

Cases

• Heater — heats or cools a batch or stream at constant pressure
• Vessel Heater — a sealed rigid vessel heated or cooled
• Fluidized Bed — sizes a fluidized bed
• Heat Exchanger — two streams exchanging heat
