Gas liquid solid compact cyclonic separator
A compact cyclonic separator is described which can handle mixtures of solids, liquids and gases in one vessel and provide continuous separation.

c. a top exit point from said vertical cylindrical tube for transporting gases;
d. a centralized vertical pipe that extends from the bottom of said vertical cylindrical tube to a point below said top exit point;
e. a first bottom exit point for transporting liquids from said vertical cylindrical tube in communication with said centralized vertical pipe; and
f. a second bottom exit point for draining solid rich slurry mixtures from said vertical cylindrical tube.

17. The apparatus of claim 10 further comprising a motor to rotate said centralized vertical pipe.
18. The apparatus of claim 17 further comprising spiraled fins, ridges, or ribs attached to the outside surface of said centralized vertical pipe.
19. The apparatus of claim 10 where a motor moves said bottom sealing means vertically.
20. The apparatus of claim 16 further comprising spiraled fins, ridges, or ribs attached to the outside surface of said centralized vertical pipe.
21. The apparatus of claim 10 further comprising a motor to rotate said bottom sealing means.
22. A method for separating a mixture of solids, liquids, and gases comprising the steps of;
a. feeding said mixture into a vertical cylindrical vessel at a tangential angle, wherein said mixture enters said vertical cylindrical vessel through a tangential inlet at a positive (i.e. downward flow direction) angle with respect to horizontal;
b. withdrawing clean liquids from a first bottom point of said cylindrical vessel
c. withdrawing a solids rich slurry from a second bottom point of said cylindrical vessel; and
d. withdrawing a gas stream from a top point of said cylindrical vessel.
23. The method of claim 22 further comprising inflating an inflatable element within said cylindrical vessel.
24. The method of claim 22 wherein said step of withdrawing a solids rich slurry comprises the step of moving a bottom sealing means of said cylindrical vessel in a vertical direction.
25. The method of claim 22 further comprising rotating a vertical pipe located in the annulus of said cylindrical vessel.
26. The method of claim 22 further comprising rotating a bottom sealing means of said cylindrical vessel.
