Crude units, hydrotreaters, and the octane that hand-trending tends to leave on the table, so you can trace a RON drop across the NHT before the next blend leaves the rack.
Batch and continuous operations with tight quality windows, where exchanger fouling shows up early even when seasonal cooling-water swings mask it.
Heat-rate creep, condenser vacuum, and the derates that quietly cost megawatts, traced from symptom to cause before the next dispatch.
Lift stations, DAF units, and compliance deadlines, with an agent for each engineer so small teams cover wide plants comfortably.
Furnaces, dryers, compressed-air systems, and OEE, where the graph reads a production line the same way it reads a process unit.
