4. Evacuation of liquid phases
Two main techniques are used for both separators and decanters.
-
Free exit
The liquid is ejected from the bowl and collected in a collector in the separator housing. The product leaves the machine by gravity, and a pump must be used if the product is to be conveyed.
-
Turbine discharge
A turbine, installed on one or more liquid phases, delivers the treated product under pressure. Discharge pressure can reach 6 to 10 bar.
The product comes into much less contact with the ambient air than with a free outlet.
Figure 14 shows the turbine discharge principle.
