iLEAN for petrochemical: predictive OT/IT maintenance
In petrochemical, an unplanned column shutdown costs what it costs — and OT/IT integration is notoriously delicate. iLEAN brings predictive maintenance and regulatory records (ISO 14001, ISO 45001, ISO 50001) without forcing you to replace the SCADA you already have.
A column shutdown costs what it costs
In petrochemical, an unplanned distillation column shutdown costs between 100k and several million euros depending on refinery type. OT/IT integration — connecting process control (DCS, SCADA, PLC) with management (ERP, MES) — is notoriously delicate because any error can affect operational safety.
iLEAN brings predictive maintenance and regulatory records (ISO 14001, ISO 45001, ISO 50001 for energy efficiency) without forcing you to replace the SCADA you already have. The integration respects the Purdue Model security zones.
iLEAN doesn't replace the method — it brings it into the 21st century.
Every Lean methodology was born to solve an information problem: where stock is, which machine is failing, what changed shift-to-shift. When information is paper, methods are rituals. When it's live data, they become the actual engine of the plant.
Classical method tells you what to measure. The IRIS system guarantees the measurement reaches whoever decides, the moment they decide — without anyone typing it in.
The three capture layers applied: Connect (photo, voice, email, WhatsApp), Edge (computer vision on the line) and Integrations (ERP/MES/SCADA/PLC). On top of that unified information, specialized agents serve the exact context to each person on the floor.
What iLEAN covers in a refinery or petrochemical plant
| Area | Petrochemical need | iLEAN coverage |
|---|---|---|
| Maintenance | Predictive of columns, furnaces, critical pumps | TPM with predictive AI + non-invasive sensors |
| OT/IT integration | Without operational safety risk | Respects Purdue Model, OPC UA connector |
| Safety | ISO 45001, event log | Digital Andon + per-alarm traceability |
| Environment | ISO 14001, emissions, spills | Emission tracking + drift alarm |
| Energy efficiency | ISO 50001 | Auto kWh per produced unit |
What people ask about iLEAN in petrochemical
What does iLEAN cover in a refinery or petrochemical plant?
Five critical areas: predictive maintenance of columns and rotating equipment, safe OT/IT integration (SCADA with ERP), operational safety ISO 45001, environment ISO 14001, and energy efficiency ISO 50001.
How does iLEAN integrate OT (SCADA) with IT (ERP) safely?
iLEAN respects the Purdue Model of OT network levels — security zones. It sits at level 4 (plant IT) consuming data from the DMZ (level 3.5) that the OT team controls. It never writes directly to DCS/SCADA. Extraction uses standard OPC UA.
Does iLEAN reduce corrective maintenance on critical columns?
Yes, typically 30-50% in the first 12-18 months once the AI agent has learned each equipment's patterns. The key: column, pump and compressor failures are rarely sudden — they have gradual drift in vibration, temperature or electrical consumption. iLEAN detects that drift.
Does iLEAN comply with ISO 14001 and ISO 45001?
iLEAN supports the operational side of both standards — data capture, event logging, drift alarms, audit reports. The certification itself is granted by an accredited auditor after evaluating your management system; iLEAN gives you the tools to pass the audit with margin.
Does iLEAN work with a 15-year-old SCADA?
Yes. As long as it has classic OPC or OPC UA (most SCADAs since 2005 do), iLEAN connects. For very old SCADAs without OPC, we install a level-3 gateway that translates proprietary protocols.
