Luma Process Intelligence — Drift Monitor

Three hypothetical runs over a 14-day rolling window (2026-04-21 → 2026-05-04) on the same engineering drawings the P&ID Reviewer demo ships with. No alarms have tripped in any of these runs — every signal sits below its configured threshold. This is what Luma surfaces in the quiet zone between nominal and alarm.

   WARNING

   kWh/t · multivariateon Train 1 rollup (C-101…C-104)

   Specific power on Train 1 trending +3.2 % over 14 d at constant feed; root cause = E-102 fouling + CW drift + C-104 valve flutter.

   RecoCoordinated fix in next 7-d window; expected payback 2.1 d once all three corrected.

   Pattern matches 2025-09 valve-plate-wear precursor on C-103: PT lagging TT by 38 min, dP narrowing.

   RecoBorescope C-103 cylinder at next opportunity; pre-stage valve kit.

   CW supply T now +1.4 °C above 14-d baseline; co-trends with all E-1xx hot-side outlets — affects every exchanger duty in feed-prep.

   TT-105 / TT-106on E-105 (interstage cooler)

   C-105 outlet hotter than C-106 inlet by 1.4 °C — interstage cooling drift on E-105, likely tube fouling on process side.

   Interstage dP variance collapsed from ±0.18 → ±0.05 bar — pulsation dampener saturating; combined with rising suction T → −2.1 % stage efficiency.

   RecoVerify nitrogen precharge on dampener bottles for C-101 and C-102; test pulsation profile under no-load.
