Abstract
A flow comprising solid particles in a fluid suspension under pressure, typically the rejects flow from a separator, is conducted to a vortex flow chamber. In the vortex flow chamber, added liquid flow is caused to whirl and the reject flow containing contaminants is squeezed towards the axis of the vortex flow chamber and accelerated axially. This prevents plugging of a flow control valve connected to the vortex flow chamber outlet.
