HYDROCYCLONE LINER WITH IMPROVED INNER WALL STRUCTURE AND METHOD FOR REMOVING OIL FROM PRODUCED WATER USING SAME

摘要

The present invention relates to a liner for removing oil of a de-oiling hydrocyclone step used for a produced water treatment system for treating produced water including a large quantity of oil generated during oil extraction, wherein an internal wall structure of the liner is optimized, so that the separation efficiency of oil components from produced water including a large quantity of oil can be effectively improved compared to an existing liner. The liner of the present invention is divided into a first domain, a second domain, and a third domain which have different slopes of liner internal walls extending from one side end of the liner where a top discharging unit is disposed to the other side end of the liner where a bottom discharging unit is disposed. The liner internal wall of the first domain is deformed into various shapes in order to be optimized, and a vortex is generated by means of a centrifugal force. From produced water including oil induced through an inducing unit disposed in the first domain, oil components which account for a relatively small weight in the produced water are discharged through a top discharging unit, and water components which account for a relatively large weight in the produced water are discharged through a bottom discharging unit disposed in the third domain after passing through the second domain disposed at the bottom of the first domain.;COPYRIGHT KIPO 2014
