<p>A hydrocyclone separator (70) separates an oil and water stream (71) into a underflow stream (76) containing primarily water and an overflow stream (74) containing a relatively higher oil concentration than the underflow stream (76). Quality control of both the underflow stream (76) and the overflow stream (74) is of concern, and typically a deoiling separator (82) is placed downstream on the underflow stream (76) and a dewatering separator (14) is placed downstream on the overflow stream (14) from the hydrocyclone separator (70). A degassing separator (12) is also generally utilized upstream of the inlet (72) to hydrocyclone separator (70). Various monitoring and control systems (32, 73, 57 and 61) are provided for controlling the split ratio of the underflow streams (74 and 76) of the hydrocyclone separator (70).</p> |
