In fact, as reported in Table 6, in the 50 mm SM, on the basis of eq 8 the low-velocity case (a) corresponds to 0.9 m/s and the high-velocity case (b) to 3.0 m/s; the corresponding biodiesel yearly productions (estimated at 90% conversion and for a 300 d/y continuous process) are typical of a plant of medium-large size ((3.0–9.8) × 104 t/y).
