Industries/Chemicals & Process

Process safety information that stays current.

For chemical and process manufacturers. Operon keeps P&IDs, equipment records and MOC history connected, so PSM documentation, PHA revalidation and everyday questions start from current, verified drawings.

From drawing to plant

Every tag on the P&ID is a piece of steel in the unit.

The feed drum, pumps, control station and exchangers of a naphtha stabilizer, drawn as they stand. Hover a part to see its tag and the line runs Operon connects to it.

The work today

What chemical engineering teams face today

Legacy documentation

Thousands of P&IDs across decades of modifications, many still on paper or in obsolete CAD formats.

Knowledge silos

Critical process knowledge trapped in individual engineers' heads, unstructured documents and disconnected databases.

Compliance burden

Process safety rules require documentation to stay current with every change, and keeping it current consumes engineering hours.

Simulation drift

Process models fall out of sync with the plant as it is modified, and predictions get less reliable with every change.

What Operon does

PSM documentation

Process safety information that keeps up.

P&IDs, equipment data and relief system records kept connected and current, with every change traceable to the MOC that made it, so PSI is ready when an auditor or a PHA team asks.

New revisions update the graph; stale documents are flagged.
Every change links to its MOC record.
Evidence is assembled from the graph, not from a scramble.

PHA & HAZOP preparation

Start revalidation from the current P&IDs.

Node lists, equipment and line inventories, and what changed since the last PHA, drafted from the verified graph, so the team's time goes into the hazards rather than the paperwork.

Equipment and lines grouped into nodes for the team to adjust.
Every MOC and revision since the last study, listed by node.
Shaped for the PHA software or spreadsheet you use.

MOC revision deltas

Every change, and everything it touches.

Revisions diffed against the last, with graph traversal showing connected instruments, relief devices and equipment. MOC reviews start from a structured list instead of an overlay.

Added, removed and changed items, by sheet and region.

Plant knowledge chat

Ask the plant. Get the drawing.

Search thousands of sheets and records in plain language. Every answer resolves to the tag, the line and the drawing region it came from, so engineers trust it enough to act on it.

Sheet, revision and region behind every answer.
Drawings, datasheets and MOC history together.
When the documents don't support an answer, Operon says so.

Which relief valves protect E-201, and when did their set pressure last change?

Two: PSV-1302 on the shell side and PSV-1305 on the tube side. PSV-1302 moved from 150 to 165 psig at Rev D under MOC-2291.
