OIL DEHYDRATION APPARATUS Russian patent published in 1996 - IPC

FIELD: treatment; dehydration of oil by gravitational settling of water-oil emulsion. SUBSTANCE: apparatus has settler, starting emulsion inlet line and dehydrated oil and separated water lines. Outlet hole of gas-discharge passage of gas separation unit is in direct communication with part of chamber of settler above intermediate layer. Fitted at outlet of inlet line of unit chamber is baffle with concave working surface. Defoamer is mounted in gas collecting chamber of inlet unit. Inlet unit makes it possible to separate gas from starting emulsion before it enters water zone and discharge it to oil zone past intermediate layer. As a result, its structure is retained and unbroken components of emulsion and mechanical admixtures are kept from being discharged into oil zone. EFFECT: enhanced efficiency. 3 cl, 1 dwg
