One connected project
Design basis, components, block flow diagrams, process flow diagrams and piping and instrumentation diagrams live in one project file, so a change in one place is visible everywhere.

BLACK OWL / PROCESS ENGINEERING
Early access · Desktop applicationDesign basis to P&ID in one connected project, with no re-keying between spreadsheets and drawing tools.
Define your design basis. Build flow diagrams. Balance your process and develop engineering deliverables — with the project context kept together.
CONNECTED PROCESS ENGINEERING
Move from a design basis to flow diagrams, balances and engineering deliverables in one project.
Black Owl brings the context of early engineering work together: the components you define, the streams you connect and the equipment you develop. Built for chemical and process engineers working through the decisions that shape a plant.
Discover the platform ↗01 / THE WORKFLOW
From first assumptions to detailed diagrams, Black Owl follows the way early engineering work progresses.

02 / CAPABILITIES
Design basis, components, block flow diagrams, process flow diagrams and piping and instrumentation diagrams live in one project file, so a change in one place is visible everywhere.
Draw process blocks such as mixers, reactors and splitters, and connect them with numbered streams that carry phase, flow, temperature and pressure.
Place pumps, vessels, heat exchangers, reactors, columns, mixers, condensers and splitters, and route the lines between them.
Run the material balance from the block flow diagram and see mass flows on each stream, with a status showing whether the results are current.
Maintain the components for the project, with molecular weights used by the balance.
Choose the property package and mixing rule for the project. Package suitability depends on your system; you remain responsible for that choice.
04 / WHO IT’S FOR
Black Owl is made for the early, decision-heavy stages of a process project, before detailed design takes over.
Take a process from design basis to P&ID without re-keying data between tools.
Keep each project’s basic engineering in one record the whole team can follow.
Develop studies for new units and plant changes with the project context kept together.
See how early engineering work connects, from the first assumptions to deliverables.
Many teams carry early engineering across spreadsheets, drawing tools and a simulator. Black Owl keeps that work in one project.
| Early engineering task | Spreadsheets + drawing tools | Process simulators | Black Owl |
|---|---|---|---|
| Design basis | Separate documents | Usually outside the model | Captured in the project |
| Block and process flow diagrams | Drawn separately | Simulation flowsheet | Built in and connected |
| Material balance | Hand-built formulas | Rigorous models | Run from the block flow diagram |
| Equipment sizing | Separate calculation sheets | Varies by tool | From the process flow diagram |
| Piping and instrumentation diagrams | Separate drawing tool | Usually a separate product | Developed in the same project |
| Revisions and traceability | Manual file versions | Model file history | Revision and freshness tracking |
Process simulators remain the right tool for rigorous modelling. Black Owl connects the basic engineering work around your process.
ENGINEERING JUDGMENT FIRST
Software supports the process. Engineers remain responsible for the design.
Review assumptions, property-package suitability, reference defaults and calculated results against your project requirements. Black Owl is intended to support early process and basic engineering; outputs need qualified engineering review before use.

Mahesh and Mukesh develop and design the Black Owl platform and this website.
A CLOSER LOOK
A practical introduction to Black Owl.
Black Owl is an early process and basic engineering workspace for chemical and process engineers. Its workflow connects design basis, components, flow diagrams, material balance, equipment sizing and engineering deliverables.
Yes. The workspace images show Black Owl engineering demo projects. The 3D plant and animations on this page are illustrative concepts, not models produced by the application.
Black Owl is in early access. A public installer and a 14-day trial are planned. Request early access to get a walkthrough and hear first when builds are available.
Yes. A qualified engineer must review assumptions, inputs, methods, reference defaults and outputs against the requirements of the project before relying on them.
