Routing
Each step recovers its work centre's rate for the hours run, and overhead is applied on top. That is the conversion cost inside WIP.
| Seq | Work centre | Operation | Hours | Rate /hr | Recovered |
|---|---|---|---|---|---|
| 10 | RX-03 Reaction Vessel 3 (aqueous precipitation) | Aqueous metathesis, stearic acid against lime slurry | 13.4 | $310.00 | $4,154 |
| 20 | DR-01 Spray Dryer | Spray dry to <1.2% moisture, straight to the pre-blend silo | 15.4 | $265.00 | $4,081 |
