1. A separator comprising:

  • a vessel having a peripheral wall bounding a chamber, the vessel being rotatable about a rotational axis extending through the vessel, the chamber communicating with an inlet and a first outlet;

    a plurality of fins disposed within the chamber;

    a second tube extending from toward the rotational axis to toward the peripheral wall, the second tube having a first end in fluid communication with the exterior of the vessel and an opposing second end bounding a second outlet, the first outlet being disposed closer to the rotational axis than the second outlet such that during use a fluid boundary line can be formed between the first outlet and the second outlet; and

    a first tube extending from toward the rotational axis to toward the peripheral wall, the first tube being coupled with a fluid source for selectively dispensing a fluid stream at or adjacent to the peripheral wall.
