Abstract
A hydrocyclone separator separates an oil and water stream into an underflow stream containing primarily water and an overflow stream containing a relatively higher oil concentration than the underflow stream. Quality control of both the underflow stream and the overflow stream is of concern, and typically a de-oiling separator is placed downstream on the underflow stream, and a dewatering separator is placed downstream on the overflow stream from the hydrocyclone separator. A degassing separator is also generally utilized upstream of the inlet to the hydrocyclone separator. Various monitoring and control systems are provided for controlling the split ratio of the underflow and overflow streams of the hydrocyclone separator.
