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 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.
All 66 cases in petrochemical
The complete listing, unpaginated. Each link goes to the specific case: the problem as it shows up on the plant floor, how the IRIS schema solves it and what was measured.
General cases (46)
- AI control for batch chemical reactors — the reactor depends on the recipe and on the operator's eye, and that eye walks out the day they retire.
- AI wastewater treatment — a discharge breach is seen two hours too late; with iLEAN, two hours early.
- Anodized aluminum with AI — one shade out of range and the profile comes back from the customer.
- Asphalt and bitumen control with AI — the tank temperature rules, and the standard does not wait.
- Barrel and derivative traceability with AI — from incoming crude to the customer's diesel, with no gaps in the genealogy.
- Base oil control with AI — an off-spec batch is several m³ that get downgraded.
- Biofuel control with AI — chemistry, the standard and traceability cross-referenced in one place.
- Cement and clinker control with AI — the kiln drives the whole plant, and every kcal counts.
- CEMS stack emissions with AI — an analyzer in drift is not an incident, it is the quarter's reporting invalidated.
- Chemical batch traceability (lot genealogy) — a complaint six months later should not be a two-week project.
- Chemical customer specs and CoA with AI — the spec stays live, the certificate is automatic, the complaint never arrives.
- Chemical recipe optimization with AI — the raw material changes, so the recipe should change with it.
- Circular economy in petrochemicals with AI — the mass balance does not hold up in a spreadsheet; with iLEAN, it does.
- Cosmetics manufacturing with AI — the emulsion that split, the batch that passed GMP by hand and the audit that started over.
- Cracking control (FCC / steam cracker) with AI — severity, feedstock and margin on the same screen.
- Crop protection control with AI — a mislabeled drum is not an incident, it is a recall and a penalty.
