Use Cases
The warning signs are already in your mill's historian data
Pulp and paper teams are surrounded by historian data, but the engineers and operators closest to the equipment rarely have time to manually trend every refiner, headbox, vacuum pump, drainage loop, and steam circuit signal. Early warning signs of hydraulic instability and chemical imbalance get buried in CSV exports, DCS trend screens, shift logs, and alarm noise.
Grayson TimeSeries Lite helps mill teams ask direct questions of that data and get evidence-based answers backed by deterministic models.
The cost: Off-spec paper strength leading to downstream sheet breaks, wasted electrical energy and premature plate replacement or catastrophic "plate clashing."
What Grayson does: Tracks refiner motor power and current variance, vibration, hydraulic plate-gap clearance, inlet/outlet stock consistency, feed flow rate, and casing temperature differential to surface multi-variable signatures of plate bar wear, hydraulic feed instability, or fiber starvation.
Ask Grayson: "Here is the last 30 days of motor load, vibration, plate gap clearance, and inlet consistency for Refiner 3. Are the trends showing signatures consistent with plate bar wear or hydraulic feed instability?"
Outcome: Empowers stock prep operators to prove whether a drop in pulp freeness is driven by feed consistency swings versus actual mechanical plate wear, optimizing plate change schedules and preventing costly plate clashes.
The cost: Massive production losses from web, broke reprocessing costs, wasted chemical additives, and operator burnout from constant thread-ups and cleanup.
What Grayson does: Analyzes headbox pressure stability, slice opening, retention aid dosing flow, white water consistency, pH, conductivity, turbidity, and couch roll vacuum levels to detect developing cyclic disturbances, chemical drainage imbalances, or furnish instability before the web breaks.
Ask Grayson: "Look at the headbox pressure, wire pit pH, retention aid flow, and couch vacuum tags over the last 12 hours on PM2. Is there an emerging cyclic disturbance or multi-variable oscillation correlated with our recent sheet breaks?"
Outcome: Helps paper machine operators shift from reactive sheet-break cleanup to proactive wet-end stabilization by pinpointing exactly which chemical dosing loop or hydraulic oscillation is driving process variance.
The cost: Unplanned mill-wide shutdowns for boiler water-washing, excessive sootblower steam consumption, and severe thermal efficiency losses.
What Grayson does: Tracks black liquor firing rate, dry solids concentration, superheater tube skin temperatures, flue gas differential pressure across boiler banks, combustion air flow, and sootblower steam usage to quantify fouling rates and identify combustion zone instability.
Ask Grayson: "Here is 60 days of flue gas differential pressure, superheater temperatures, black liquor solids concentration, and sootblowing steam flow for Recovery Boiler 1. What is the current rate of tube fouling compared to baseline, and are sootblowing cycles effectively restoring clean-tube heat transfer?"
Outcome: Provides recovery area engineers with clear, data-backed evidence to optimize automated sootblowing schedules and accurately forecast required water-wash outages without risking unplanned shutdowns or wasting high-pressure steam.
