Feb. 16` 1926l 1,573,532 c. M. ALEX-ANDER n PROCESS AND APPARATUS FOR DECOMPOSING OIL'Sv Filed Oct.' 9, 1919 to time in order to clean out the accnmuf lated carbon. In the preferred form, however, av separate carbon collecting' chamber is used.I and consequently most of the carbon, instead. ot settling in the bottom of the still, in a hard9 dense heat-insulating layer. is carried out et the still and. depositi-uil in the. settling;- chamber.
In the drawingl l have illustrated diagraminatically an apparatus for carryingF out the several steps niy invention. In this drawingr, l indicates a still of usual torni. supported in brick work or other convenient material, and heated yin any desired manner.
Positioned withi'n the still are a. plurality ot" spraying devices El. to which. through pipes 4 and 5. the oil that is to be eracltel is led` rl`his fresh oil is preferal'ily preheated and is. at. a pres-'sure hizeh enough so that it is atolnincd as it is injected into the still. These sprayingr devices l preterabty spray the. oil in a direction transverse with "'sper to the axis ot the still l. The sprays are also positioned near the bottoni ot the still so as to pro-:luce a-lively agitation at'y that point where the carbon ordinarily7 tends to collect.
By means oi: a pipe t3 the still is in communication with a carlton-separatine chainber T'. which may be ot any desired design. its purpose beine' to allow the carbon that is carried into it mixed with the. oil to settle. while the carbon-treed oil passes troni the chamber 'i' to pipe h' through a circulating pulnp f), thence to pipe ltl and bach' tothe .still l. i
the oil in the still l is a very heavy residuuin oil. and is maintained at a tenipe"a ture of say TOO to 8000 lt. The oil level in the still l and the carbon-saperating chainla-r T is substantially the .saine7 an equalizing pip:A ll la-inp' coiuiected to the chamber and stil! l to balance the pressure.
rlhe. h e'hter hydrocarbon vapors resulting troni the crackin;v are led troni the still l by means ot a. pipe 12 to an ordinary fractionatine' tower lil: thence tliroi gli av pipe .Il to a. condenser l5 ot any suitable design.
The, still l may be operated :t high or low pressure. The. Usual residuuuns work satisfactorily at low pressure. while with certain distillates, pressure may be used. A pressure regulating' valve for the Still is shown at 1G.
The condenser similarly is operated `at high or low pressure, dependent von particular conditions. A pressure controlling valve for the condenser is indicated at 1T.
The condensate from the traetionating tower lil may he continuously run back into 'the still. and distributed over the. hot. oil contained therein through the perforated distributing' pipe 1d. rlhis will be the usual method of operation when the. pressure is controlled at 1T. When the pressure is conremesa trolled at 1G, the condensate from the fractionafting tower 13 usually roes directto the pnmp charging fresh residunm to the still.
As a mattei' ot practice, a battery of stills l may be used` they beinpr interrruineeted so that the resi'dtuun oil tlows directly from one still to the next and eventually into a carbon-selmrator i'. and thence. through a circulatingr puinp that is ett'cctire in circulating; the oil through the whole battery oli stills.
The important point ot the invention is spraying' the oil that is to be cracked into a bath of highly heated oil, the spraying .device being immersed in the highly heated oil so that it is kept in rapid circulation an'l the deposition ot carbon Ailu'eventtal. As a corollarwto the above, the heavy high temperature oil is circulated from the still through a carbon-collecting chamber and thence back to the still. having' deposited its carbon in the carbon-collet'tot'.
lt should be understood that the essentialv `features of the invention maybe carried out. in other ways than in the particular apparatus shown.
ln some eases, a' pressure ot 5 to G atmospheres may be maintained on the still; and troni l to .2 atmospheres on the tendensen I claim as niy invention:
