Apparatus and method for separation of oil from oil-containing produced water
A process for separation of oil from oil-containing produced water as well as an apparatus for separation of oil from oil-containing produced water. A perforated baffle plate is arranged in a separator tank to provide for equalizing of the downwardly flow rate of produced water. The insertion of such baffle plates has shown that less oil is following the stream downward.
