Abstract
The present invention relates to the treatment of multiphase mixtures and more particularly, though not exclusively, to multiphase mixtures in which at least two of the phases are liquids and the least dense liquid phases is present in quantities of at least 5%. One preferred application of the present invention relates to the treatment of oil/water mixtures (which may include gaseous and solid phases) such as that discharged from oil wells. Research into the use of cyclone separators for the separation of oil/water mixtures has increased in recent years. One of the reasons for a growing interest in this area is because of the particular problems associated with off-shore platforms. One of the major problems is that of the weight of processing equipment and, as a result of this, attempts are continuously being made to try and reduce the weight of processing equipment. It is with this in mind that investigations have been conducted into the use of cyclone separators.
