Operator–Process Interaction — Eliminating Shift Drift & Human Lag
Industrial process performance varies substantially from shift to shift. Senior
operators rely on unwritten intuition developed over decades, while junior operators
follow static procedures that struggle during process disturbances. When upsets
occur, control loops are frequently switched to manual mode, introducing human lag,
over-correction, and hunting cycles with dead-times of 30 to 90 minutes between
inlet moves and outlet stabilization.
Our model establishes a continuous, 24/7 digital baseline, creating a clear path
from advisory support to full closed-loop automation:
Current Baseline (Operator Dependent)
Performance depends entirely on individual operator experience and manual intervention.
Copilot Stage (Advisory Guidance)
The model runs continuously, suggesting optimized process settings directly on the operator console.
Autopilot Stage (Autonomous Closed-Loop Control)
Once proven, the system writes optimized setpoints directly to the DCS, while operators act as supervisors.
Yield Optimization — Reclaiming Hidden Capacity & Safe-Optimal Operating Points
Because raw material feed quality fluctuates and equipment ages over time (catalyst
decay, heat exchanger fouling), operators traditionally apply conservative setpoints.
Plants routinely run 3% to 8% below true optimal yield to avoid process trips or
off-spec batches. Because pure data models cannot separate sensor drift from
physical fouling, decisions are made on the wrong physical reality.
Because our grey-box model identifies real physical parameters, it accurately
distinguishes sensor degradation from equipment fouling. This enables plants to
shift safely from conservative setpoints to safe-optimal operating points—unlocking
hidden capacity without risking off-spec runs.
Soft Sensing — Displacing Lab Delays & Eliminating Operational Blind Spots
Process and maintenance engineers are often forced to run blind. Critical quality
parameters—such as internal dryer moisture, chemical composition between analyzer
samples, internal machine wear, or unmetered fluid flows—are either unmeasured or
measured via offline laboratory samples with delays of hours.
Our calibrated model acts as a continuous real-time soft sensor, accurately
inferring unmeasured internal states from mass, energy, and momentum balances. This
displaces expensive online analyzers and their calibration burden, closing
laboratory feedback loops in seconds instead of hours.
What-If Analysis — Direct Conversational Asset Answers
Plant engineers and shift leads regularly face structural questions that historical
data cannot answer. Teams ask questions in plain language against the asset graph
and model. Answers arrive in seconds with stated physical uncertainty bounds,
avoiding risky plant trials or weeks of offline consulting studies.
- What is the exact sensitivity of production yield to a specific setpoint adjustment?
- What happens to plant capacity if a valve sticks or a heat exchanger fouls by 15%?
- Can the line handle an additional feed pump, a larger heat exchanger, a new recipe, or a different feedstock?
