More Information
Summary:A system and method for improving oil-and-water separation in a blended fluid stream are presented. The system includes a pressure reduction device that causes cyclonic flow in the stream. The pressure reduction device may be a wafer-based hydrocyclone or a modified hydrocyclone having an underflow outlet but no overflow outlet. The system may also include a valve that is located upstream or downstream of the pressure reduction device. Both the valve and the pressure reduction device reduce the pressure of the fluid stream while reducing the shearing of oil and water droplets within the stream. As a result, the droplets are more likely to coalesce and less likely to form emulsions, thus improving oil-and-water separation in downstream treatment processes.
