Q = required operation flow [l/h]
P = MCR (maximum continuous rating) [kW]
t = actual effective separator unit separating time per day
[hour]
(23.5 h separating time and 0.5 h for sludge discharge = 24
h/day)
n = number of turnovers per day of the theoretical oil volume
corresponding to 1.36 [l/kW] or 1 [l/HP]
The following values for "n" are recommended:
n = 6 for HFO operation (residual)
n = 4 for MDO operation
n = 3 for distillate fuel
Example 1
For multi-engine plants, one separator unit per engine in operation is recom-
mended.
For example, for a 1,000 kW engine operating on HFO and connected to a
self-cleaning separator unit, with a daily effective separating period of 23.5
hours, the calculation is as follows:
