}Cascade — 10 agent steps
| # | step | agent | detail |
|---|---|---|---|
| 1 | INJECTION | Injection Engine | column_flooding_drift: HP column flooding creeping to 85% (alarm at 90%). Tray hydraulic limit approaching. |
| 2 | MPC_SOLVE | MPC Optimizer | 📐 MPC: Optimal load 65% (4h horizon) | Priority: 2 | Expected margin: $0/h | Reason: Swarm [SWARM-0019|periodic_review]: reduce load by 5% and dr |
| 3 | PHYSICS | Physics Kernel | Flooding occurs when liquid backs up on trays faster than vapor can rise. Above 90%: liquid carryover contaminates vapor → purity crash. Above 95%: column trip. |
| 4 | PRODUCTION | Production Agent | HOLD at 60%. Consider reducing reflux or adjusting feed rate. If flooding exceeds 90%, mandatory load cut. |
| 5 | TANKS | Tank Inventory Agent | LOX at 60%, LIN at 61%. Flooding reduces separation efficiency → less pure product. |
| 6 | DISPATCH | Dispatch Agent | Normal dispatch. Watch GOX purity trend — flooding causes purity to drop before it triggers a trip. |
| 7 | CUSTOMERS | Customer Impact Agent | If purity drops below spec, off-spec product must be diverted. Customers expecting pipeline GOX get nothing. |
| 8 | LOSS_MITIGATION | Loss Ledger | 📉 L1: Primary Production Physical Balance — PROC reduces load before flooding causes off-spec venting |
| 9 | ECONOMICS | Economics Agent | Column trip = full plant restart (24h). Revenue loss: $1.2M/day. Preventing trip by load management is critical. |
| 10 | RECOVERY | Recovery Planner | 1) Reduce feed to column if flooding >88%. 2) Check tray damage. 3) If persistent: shutdown for tray inspection (24-48h). |
Raw effects
- HP flood now 55% at NE-01
- column_flooding_drift: HP column flooding creeping to 85% (alarm at 90%). Tray hydraulic limit approaching.
- 📐 MPC: Optimal load 65% (4h horizon) | Priority: 2 | Expected margin: $0/h | Reason: Swarm [SWARM-0019|periodic_review]: reduce load by 5% and dr
- Flooding occurs when liquid backs up on trays faster than vapor can rise. Above 90%: liquid carryover contaminates vapor → purity crash. Above 95%: column trip.
- HOLD at 60%. Consider reducing reflux or adjusting feed rate. If flooding exceeds 90%, mandatory load cut.
- LOX at 60%, LIN at 61%. Flooding reduces separation efficiency → less pure product.
- Normal dispatch. Watch GOX purity trend — flooding causes purity to drop before it triggers a trip.
- If purity drops below spec, off-spec product must be diverted. Customers expecting pipeline GOX get nothing.
- 📉 L1: Primary Production Physical Balance — PROC reduces load before flooding causes off-spec venting
- Column trip = full plant restart (24h). Revenue loss: $1.2M/day. Preventing trip by load management is critical.
-
- Reduce feed to column if flooding >88%. 2) Check tray damage. 3) If persistent: shutdown for tray inspection (24-48h).
