G-USTA'V' EGLOFF AND HARRY I?. BENNER, OF INDEPENDENCE, KANSAS, ASSIGNORS T UNIVERSAL OIL PRODUCTS COMPANY, OF CHICAGO, ILLINOIS, A. CORPORATION OF SOUTH DAKOTA.

APPARATUS FOR TR-EATING HYIJRCARBN OILS.

Application filed July 15, 1920, Serial To all 'whom t may conce/fa:

Be it lrnown that we, Gos'rsv Boitiers and HARRY l). Berman, citizens of the United States, residing in the` city of Independence,

county of Montgomery, and tritate of liansas, have invented certain new and useful Improvements in Apparatus for Treating Hydrocarbon Oils, of which the following is a specification.

This invention relates to improvementsIl in apparatus for treating` hydrocarbon oils and refers more particularly to an apparatus for cracking etroleum.

The object of the invention is to provide a construction which obtains a maximum ellioiency and utilization of the heat units in the cracking of the oil and which, at the same time, prevents local deposition of carbon or the formation of hot spots on the lower part of the still. Other objects of the invention will appear from the description of the apparatus hereinafter set forth.

In the drawings:

Fig. 1 is a view, partly in vertical section r and partly in side elevation, of our improved invention.

Fig. 2 is a transverse sectional view showing the arrangement of the flushing nozzles.

F ig. 3 is a detail view of the flushing member.

Referring in detail to the drawings, 1 designates the furnace wall provided with stack 2. Extending through this furnace is a heating element or tube 3, which prefer ably takes the form of a shell having corru gations Il. Gas or other fuel is supplied to the tube 3 by the burner 5. The gases of combustion pass out through the rear end of the tube 3 to the stack 2. Extending around and preferably concentrically with the tube 3 is the cylindrical still member 6. This still 6 is provided with manholes 7, liquid drawoff 3, controlled by throttle valve 9 and vapor outlet or dome 1t). The dome 1() is connected by pipe 11 with the lower end of the dephlegmator 12. A valve 13 is interposed in the pipe 11. The dephlegma tor 12 is provided with a plurality of inclined ball-le plates 111 and at its lower end with the right-angled partition member 15, having a spaced cap 16. The uncondensed vapors or gases pass out of the upper end of the dephlegmator through pipe 17 in which No. 396,472. Renewed July 16, 1924:.

is interposed valve 18. The pipe 17 leads to condenser coil 19 seated in condenser box 2t). The lower end of this coil 19 leads to the oil receiver 2l.. The receiver 21 is provided with pressure gauge 22 and liquid level gauge 23. lt also has liquid drawo'lf 211, controlled by valve 25, as well as gas outlet 26 controlled by a similar valve 27. The reflux condensate passes from the dephlegmator above the member 15 to the pipe 23 leading to the still as shown. rt, valve 29 is interposed in this line 28.

Fresh oil is introduced in the following manner: The inlet side of the pump 30 is connected by line 31, controlled by valve 32 to any suitable source of supply. This supply may be cool oil or preheated oil. The discharge side of the pump is connected by line 33, controlled by valve 34:, to the header 35 of the flushing nozzle. This flushing nozzle is provided with a plurality of nozzle units 36, which extend into the still and circuinferentially around the adjacent end of the heating unit 3. The header 35 may talre the form of a ring provided at one side with a series of radially projecting members 36, which preferably have contracted openings 37. The arrangement is such that the oil introduced through the nozzles constantly sweeps in the form of jets of spray, across the hot surface of the tube 3. Preferably the liquid level of the oil in the still is mainn tained somewhat above the top of the burner element 3. In this construction, the precipi* tated carbon tends to fall onto the bottom of the still with the heavier residue which can be constantly drawn off through the line 8. If desired, the residue in the bottom of the still may be. from time to time, flushed out through the line 38, leading to the lower part of the still and provided with control valve 39.

Preferably, the oil is introduced through the nozzle elements at relatively high pres sure and velocity so as to tend to sweep any carbon off the heating element.

TWe claim as our invention:

1. In an apparatus for treating oil, the combination with a still, of an annular heating element extending therethrough, means for introducing oil into said still comprising a flushing member, having a plurality of nozzle elements extending circumferentially around the heating element and adjacent the latter, a supply pump and connections between said pump and flushing member.

2. In an apparatus for treating oil, the combination with a still, o an annular heating element extending therethrough, means f for introducing oil into said Still under pressure comprising a flushing member adjacent the heatingelement, a supply pump and connections between said pump and flushing member.

y 3.` In `an apparatus for treating oil, the combination With a stilhofaheating element extendingtherethrough, means for forcing oil under pressure along and around the pe rphery of said heating element comprising a Hushing member extending circumferentially around the heating element and adj acent thereto.

4L. In an apparatus for treatingV oil, (he

combination with a Still, of a heating element extending therethrough, means for forcing oil under pressure along and around the periphery of said heating element, and means for Flushing out the residue content in the lower portion of the still* GUSTAV EGLOFF.
