About

ProcessModelling

Features
Read full description

ProcessModelling is a professional steady-state process simulation tool for gas processing and pipeline engineering โ€” built for macOS, iPad, and iPhone, so it goes with you into the field, not just to a desk. Model complete flowsheets using industry-standard thermodynamics and a full set of common unit operations, then check results against your own hand calculations or a full-scale simulator. KEY FEATURES Peng-Robinson and Soave-Redlich-Kwong equations of state Full unit operation set: Valve, Heater, Pump, Compressor, Expander, Mixer, Splitter, Pipe, Separator, Scrubber Beggs & Brill multiphase pipe flow correlation for wet and multiphase pipelines Recycle, with accelerated convergence, and adjust blocks for modelling flexibility Component splitter for basic conditioning operations (eg. dehydration) Automatically generated block diagrams of your model, with PDF export A bundled example model and full in-app user manual to get started quickly BUILT TO MAKE YOU THINK, NOT JUST CLICK ProcessModelling isn't a drag-and-drop flowsheet editor. Every model is written as a clear, explicit deck โ€” every stream, every piece of equipment, every condition, stated in your own words. That's a deliberate choice: it's easy to stitch blocks together by eye until something converges without ever really thinking through the process you're describing. Writing it down forces that thinking to happen. An in-app keyword assistant helps you write decks quickly โ€” inserting the correct shape of any block, with placeholders showing exactly what's expected โ€” without ever guessing a value on your behalf. Developed and cross-checked throughout against established process simulation practice.

Verdict

The call

The clearest difference is in-app purchases: FireAngel Connected at none against ProcessModelling's 1. FireAngel Connected also leads on iOS requirement (15.6 vs 17.6). ProcessModelling's advantage is update cadence (every 8 days vs every 2 months). On price, ads and device support there is nothing between them.
