ABSTRACT:
Separation of oil from an aqueous condensate is effected by feeding the condensate into the headspace of a liquid pool containig separation tank so that a layer of oil will settle on top of water in the pool. An oil-receiver tank above the separation tank and connected thereto by a vertical pipe, also has a liquid pool therein above which a head space at sub-atmospheric pressure exists. Oil in the layer is accessed with a lower entry to the vertical pipe submerged below the separation tank liquid level and ascends into the pipe and upwardly to the oil-receiver tank, the oil ascent being accompanied by descent of water from the liquid pool in the oil-receiver tank. When the oil-receiver tank and an upper section of the vertical pipe are filled with oil only, the oil-containing tank can be drained. Separation operation can resume following reestablishment of the liquid pool in the oil-receiver by inletting a quantity of clean water thereto.
