Title: Process and apparatus for reclaiming oils
IPC: C10M175/00
Filed: 1932-08-10
Abstract: <PICT:0393125/III/1> Used crank-case, engine, transformer and other mineral oil is made fit for re-use by heating and settling, heating with castor oil saturated with mineral oil, passing in superheated steam, cooling to about 70 DEG  F. and centrifuging, adding decolorizing material and filtering.  For example, used oil is settled in a tank 1 provided with a closed steam coil 2; water and other impurities are run off through a valve V, and the oil is passed by a pipe 3 to an oil-jacketed vessel 4 in which it is mixed with 10 per cent by volume of a reagent formed by saturating castor oil at 160 DEG  F. with a heavy red or pale mineral oil of high specific gravity; the oil and reagent mixture is heated to about 250 DEG  F. and steam at 600 DEG  F. passed in through a pipe 13 and the hollow shaft 9 of the stirrer; the steam and lighter hydrocarbons are passed to a condenser 16 and are used for power or other purposes; when the original flash point of the oil has been restored the mixture in the vessel 4 is cooled to 90-100 DEG  F. with continuous agitation, preferably 3 per cent of ethanolamine or other agent facilitating separation of the reagent is added, and the whole passed to a centrifuge 18 which delivers the reagent and deleterious matters to a receptacle 20; the oil is passed through a pipe 21 to a vessel 22 in which it is heated to about 260 DEG  F. and mixed with fuller's earth from a hopper 24 for about 1 hour; it is finally passed by a pipe to a steam-jacketed pressure filter 27 maintained at 212 DEG  F. or over.  The oil may be filtered again or/and blown with air, or may be bleached in any usual manner. The reagent may be reclaimed by diluting the sludge in the receptacle 20 with industrial alcohol, filtering or/and centrifuging to remove suspended impurities, adding petroleum spirit to precipitate dissolved impurities, filtering or/and centrifuging, washing with water to extract ethanolamine and distilling.
