Abstract: A compact cyclonic separator is described which can handle mixtures of solids, liquids and gases in one vessel and provide continuous separation. The invention operates by providing tangential flow into a vertical cylindrical tube and utilizing the tangential flow and gravity to separate into a gas stream, a clean liquids stream, and a solid rich slurry mixture. Several embodiments for controlling the flow of the solid rich slurry mixture are described.
