Plate Heat Exchanger Thermal-Performance Drift
The cost: A thermal process can continue meeting its outlet-temperature target while demanding more heating-medium valve output or showing higher pressure drop. Without comparable product, flow, inlet-temperature, and steam conditions, the team may spend hours separating normal run variation from a persistent performance shift.
What Grayson does: Analyzes a prepared dataset containing product inlet and outlet temperatures, product flow, heating-medium valve output, section differential pressure, steam-supply pressure, recipe or SKU, production state, and any prepared normalized pressure metric. Trend, anomaly, correlation, and period-comparison analysis can show when the historical relationship changed and whether it persisted under comparable conditions.
Ask Grayson: “Compare the first and final three hours of this forward-flow production run under comparable product flow and steam-supply pressure. When did heating-valve output and normalized pressure drop begin moving away from the earlier baseline?”
Outcome: Help the process or maintenance engineer identify a defensible timeline for inspection of plates, sensors, steam supply, traps, valves, and operating context.
