HFO Purifier - Throughput
HFO separator throughput from engine consumption + purifier efficiency - undersized purifier → poor fuel oil quality.
Required throughput
2.59t/h
Status
Adequate
Formula, assumptions, and limits
$$\dot V_{req} = \dot V_{fuel} / \eta$$
Slow-speed 2-stroke with HFO needs ~1.5–2× fuel consumption in purifier throughput. Dual-purifier with 50 % overlap for redundancy. Feed T to 98 °C for HFO.
