Powerful Process Engineering

Everything you need to model, simulate, and optimize production processes

⚗️

20+ Unit Operations

Reactors, mixers, splitters, heat exchangers, centrifuges, filters, distillation columns, dryers, evaporators, and more.

⚡

Real-Time Calculations

Automatic mass and energy balance propagation across your entire flowsheet as you build.

🎨

Visual Flow Editor

Drag-and-drop process nodes onto a canvas, connect them with material, energy, or signal streams.

📊

Stream Data Tooltips

Hover over any edge to see flow rate, temperature, pressure, composition, and energy data.

🔄

Templates & Autolayout

Start from pre-built templates for common processes, with intelligent automatic layout.

🖥️

Custom Code Nodes

Write custom JavaScript/TypeScript calculations in a sandboxed Monaco editor for advanced modeling.

How It Works

Three simple steps to model any production process

Drag & Drop

Pick unit operations from the sidebar palette and drop them onto the canvas. Configure parameters like temperature, pressure, and flow rates.

Connect Streams

Link nodes with material, energy, or signal edges. BioCon automatically propagates stream data through the flowsheet.

Analyze Results

View real-time mass & energy balances, stream compositions, and node calculations. Export or save your models.
