Process engine

Built on it

• Air dispersion — Stacks to plumes on the site plan.
• Chemical and process engineering — Process sheets for CadCraft, BimCraft and PartCraft: reactor recycle, exchanger duty and area, a two-component flash, reactor volumes and Antoine vapour pressure.
• Consequence modelling — Dispersion, fires, explosions on the site.
• Heat exchangers — Rating and design with data sheets.
• Pipe fitting loss constants (2-K and 3-K) - DRAFT —
• Pressure vessels — Shells, heads, nozzles, supports, reports.
• Process components databank —
• Process simulation — Flowsheets, columns, reactors, linked to the P&ID.
• Relief and flare — Relief scenarios, valve sizing, flare headers.
• Structures and properties — Draw molecules, estimate properties.
• Water and wastewater treatment — Unit processes and plant layout.

Use it in your add-on

Name it in your manifest's needs. When someone adds your add-on, their account brings this engine too, and every edition loads it the first time your add-on needs it. Version ranges arrive with AL.13.

Methods and standards

As written in the track plan (docs/0.8-PART3.md): Peng-Robinson and SRK equations of state with interaction parameters, NRTL, UNIQUAC and Wilson activity models, Henry's law, flash and bubble and dew points, recycle solving with tear streams, Fenske-Underwood-Gilliland shortcut columns, MESH columns, and conversion, equilibrium and CSTR and PFR reactors. Everything is written from published methods, never from another program's source.

Limits

Planned, not an installable engine. A calculation aid: an engineer checks every result, and nothing here is an engineering approval. Whether the databank covers your chemistry is not yet known.
