1. Scope & Interface Boundary
Defines the thermal interface between REG-WHSG-001 (NXS-Z2 high-temperature thermal recovery) and the T2 Processing steam/thermal-oil loads (T2-ITD LCI thin-film evaporator dryer; PRE-EVP-001 Liquifact™ evaporators). Physical tie-in at the RMB→PIMB thermal header wall penetration.
2. Interface Register
| ID | Interface | Medium | Parameter | Status |
|---|---|---|---|---|
| WHSG-T2-01 | NXS-Z2 thermal output | Steam OR thermal oil | 200–400°C / 10–40 bar (steam) or 200–400°C / 1–5 bar (oil) — parametric basis: T2-ITD envelope (TDS-004 Rev 3 §5.3) + PRE-EVP-001 (TDS-005). OER Gate 2 WHSG OEM confirmation. | OPEN |
| WHSG-T2-02 | NXS-Z2 thermal duty @ 400 TPD | — | 2–8 MW thermal equiv. — parametric basis: D-35. OER Gate 2. | OPEN |
| WHSG-T2-03 | Condensate return | Water | DEFINED — closed loop, zero-discharge | DEFINED |
| WHSG-T2-04 | Connector | Flanged | ASI-WTR-001 class / ASI thermal flange — confirm sizing | OPEN |
3. Heat Balance Basis
Source: MCR process gas enthalpy (Recyclotron™ train). CSC load = independent (D-65 = dedicated 915 MHz microwave; does NOT draw on WHSG). Magnetron draw 11.52 MW (D-30). Available NXS-Z1 balance ≤20.48 MW. WHSG recovers process-gas sensible heat only — no independent fired source.
4. Control & Instrumentation
SCADA via ASI-DAT-MOD-TCP (Modbus TCP/IP). Interlocks: OPEN — SCADA tag list (ties to ICD-A05).
5. Steam Scaling (per T2 demand)
| TPD | T2 steam demand |
|---|---|
| 100 | 80 kg/hr |
| 500 | 430 kg/hr |
| 1,000 | 880 kg/hr |

6. Open Actions
- D-THM-01 close: WHSG OEM heat-recovery model (OER Gate 2).
- Confirm medium selection: steam vs thermal oil (affects WHSG-T2-01/04).
7. Interface Ownership
REG side: Carbotura OEM. T2 side: Carbotura OEM. Integration/FAT: ASI.
