A refinery process flow is a high-level map of material movement through major processing units. It helps teams communicate how feedstocks move from initial separation toward treatment, conversion, blending, and storage. Unlike a detailed piping and instrumentation diagram, a process flow overview focuses on sequence and relationships rather than every valve, instrument, and control loop. This makes it useful for early planning, training, documentation, and stakeholder discussions.
Start by entering project information and selecting a feedstock. Choose a preset when you need a fast starting point, or build a custom sequence by adding units one at a time. Drag the unit cards to change their order. Add streams with names, types, origins, destinations, optional rates, temperatures, pressures, and notes. Select expected products, then generate the summary. The validation panel highlights common documentation gaps such as missing project names, empty flows, unnamed streams, or streams without destinations.
Typical refinery flows begin with atmospheric crude distillation. Vacuum distillation may follow when heavier fractions require further separation. Hydrotreating removes contaminants before downstream processing, while catalytic reforming upgrades selected naphtha streams. Conversion units such as fluid catalytic cracking or hydrocracking can turn heavier material into lighter products. Product blending combines suitable components into finished product pools. Supporting systems may include hydrogen production, sulfur recovery, utilities, wastewater treatment, and storage facilities.
The generator intentionally stays at a planning level. Real refinery design requires detailed mass and energy balances, metallurgy, equipment sizing, relief analysis, hazardous-area studies, environmental permitting, and multiple layers of process safety review. Treat values entered for flow, temperature, or pressure as descriptive project data rather than engineering calculations. Exported CSV, JSON, PDF, and print views can support meetings and records, while licensed engineers should verify every design decision before implementation.
| Unit | Purpose | Typical Input | Typical Output |
|---|---|---|---|
| Crude Distillation | Initial fractionation | Crude feed | Multiple boiling-range fractions |
| Hydrotreating | Contaminant reduction | Selected process fraction | Treated stream |
| Catalytic Reforming | Product upgrading | Treated naphtha | Reformate and hydrogen-rich gas |
| Hydrocracking | Heavy-stream conversion | Heavy gas oils | Lighter product fractions |
| Product Blending | Final product preparation | Component streams | Finished product pools |
| Storage | Inventory handling | Finished streams | Stored products |
