8. Is the process a continuous operation or a batch operation?

9. How many hours per day are
allocated to the separation process?

10. Optimum Temperature of Separation

°F --or-- °C

11. Solids in Suspension: (choose those that apply)

Does either liquid phase contain suspended
solids before separation?

Are these solid particles soluble in the other liquid phase?

Yes No

Can these particles be eliminated before introduction to the separator?

Yes No

- Specify Method:

If the particles can be eliminated by centrifugal decantation, please specify:

- the centrifugal force
(if unknown, specify decanter bowl diameter and rotational speed)
- Decanter bowl diameter
- Rotational speed

If there are no insoluble solids in the initial two phases, do any precipitates appear during the process of separation?

Yes No

In this case, after separation, are these precipitates situated:

within one of the phases
(if so, specify which phase):
on the surface of the light phase
at the bottom of the heavy phase
at the interface of the two phases

12. Special Characteristics of the Process:

Are the two phases easily mixed?

Yes No

Does an emulsion appear when the two phases are vigorously stirred?

Yes No

In the case of an emulsion:

If the phases separate by gravity, specify time required.
If the phases can only be separated by centrifugal decantation, please specify: total decantation time centrifugal force (if unknown, specify decanter bowl diameter and rotational speed) - Decanter bowl diameter - Rotational speed

Following centrifugal separation, is the interface between the two phases distinct?

Yes No

Following centrifugal separation, does one of the two phases remain cloudy?

Yes No

If yes, which phase?

Is it possible to submit samples of each phase for hydraulic characterization tests?
Approximately 250 cc of each phase is sufficient.

Yes No
