LINE FOR PROCESSING OIL RESIDUAL AND BOTTOM SEDIMENTS OF OIL REMOVERS, FLOTATORS, SLURRY TANKS Russian patent published in 1997 - IPC

FIELD: petroleum processing. SUBSTANCE: in order to increase degree of dehydration and washing solid particles from petroleum products, to increase efficiency in separation of stable oil emulsions and degree of oil residual purification on centrifugal machines, and also to reduce investment and operating expenses on plant construction, line is provided with installations in which equipment is properly disposed. Installation for collection and pumping through of oil residual includes arrangement for stirring and disintegration of oil residual and trash, bilateral combined lever hoist, and fragment of enclosure of means for transferring oil residual to intake. Installation separating oil residual and bottom sediments is provided with steam- entering means, self-cleaning filter with mechanical sediment discharge, and tank for receiving and separating oil residual with conveyer to withdraw solid impurities. Installation for washing mazut-polluted solid impurities includes combined arrangement for receiving, agitation, and washing of polluted solid impurities, solvent-entering means, and conveyer for discharging washed solid impurities. Heater-mixer in installation for processing bottom sediment is provided with arrangement for entering and distributing steam. Line also has means for entering demulsifiers. EFFECT: enhanced efficiency in processing line operation. 2 dwg
