ABSTRACT:
This invention relates to a system for separating a multiphase liquid mixture into a plurality of streams. The invention has particular utility in the oil industry where particulate solids are produced with an oil/water mixture. Preferably, the mixture is first cyclonically separated to remove particulate solids from the oil and water. Then the mixture is delivered to a liquid/liquid hydrocyclone where a substantial portion of the oil is separated from the remaining mixture which now primarily comprises water. The pressure of the remaining mixture is elevated such as by a pump and is then subjected to a further cyclonic separation step to remove any remaining fine solids in the mixture.
