. To all whom it may concern Be it known that we, GUs'rAv lEGnorF and HARRY P. BENNER, citizens of the United States, and residing in the city of Tndependence, county of Montgomery, and

lll),

' an apparatus for treating oil and refers more State of Kansas, have invented certain new and useful Improvements in an Apparatus for Treating Oil, of which the following is a specification.

This invention relates to improvements 1n the system for further treatment.

furnace provided with burners 2,

In the drawings- Fig. l is a side elevation of our invention; Fig. 2 is a top plan view thereof. Referring to the drawings, 1 desi ates a ue outl let 3. In this furnace is mounted a heating coil 4 which may be made of three inch pipe. The inlet side of the heating coilis connected to charging line 5, leading to feed pump 6, connected to any suitable source of supply. The outlet side ofthe heating coil is connected by transfer line 7 to one end of a vapor chamber 8. This vapor chamber 8 may consist of four twenty-inch tubes interconnected as shown at 9 and mounted in a suitable support 10. The vapor chamber is preferably located outside of the re zone.

The vapor chamber is provided at this far' end with a residue draw of pipe 11 having throttle valve 12. Vapors pass out of the vapor chambers at various points in .the length of the latter by means of the vertical pipes 13 .in each of which is interposed a throttle valve 14. The upper end of each pipe 13 projects into the bottomV dephleg- 'mator 14, and above the upper end of each pipe 13 is a spaced cap member 15 to prevent the reflux condensate. from flowing back into the pipe 13. Each dephlegmator 14 is provided with a series of disposed baffles 16 and at its lower end yis provided with a reflux condensate draw od' pipe 17. The two pipes" '17 at the lefthand side of the apparatus connect to a header 18 and from this header 18 a pipe 19 leads to a 'I' 20, connected in turn to the pipe 21, 'leading down to the feed lner. The reflux condensate passes out of the dephlegmator shown at the righthand side of the drawing by means of a pipe 22, connected to transversely extending pipe 23 which in turn leads to the T 20. A valve 24 is interposed in pipe 21. The pipe 21 is provided with a by-pass line 25 controlled by throttle valve 26 in case it is not desired to return any of the reflux condensate to the heating tubes.

Describing now the manner of taking off various fractions of the Ilighter' lcondensate from the dephlegmators. Each is provided with a plurality of draw olf lines 27, 28 and 29 leading to a vertical header 30. The top of each dephlegmator is provided with a vapor outlet. pipes27, 28 and 29 leading from dephlegmator 14 located nearest the heating coil has its pipes 27, 28 and 29 connected to headers 31, 32 and'33 to which the pipes 27, 28. and 294, of the adjacent dephlegmator 'are also connected. The oil or vapors may be prevented from passing through the pipes 27, 28 and 29 into the header 30 by closing the valves 34. The redux condensate or vapors can then be compelled to pass through the by-pass lines 35 and common line 36 to separate condensers and receivers or may be diverted back to the heating tubes by suitable connections (not shown).

Vapors pass out of the upper part of the dephlegmators into the pipes 37. The two at the lefthand side of the drawing are connected to a header 38 and thence lead to the main vertical header 30". Valves 39 are interposed in the line as shown.

From the top of the header 30, a pipe 40, controlled by valve 41, leads to water condenser 42 seated in condenser box 43. The bottom of this condenser coil 42 is connected to receiver 44. This receiver 44 is provided with liquid draw od 45 having throttle valve 46; gas outlet 47 having throttle valve 48. It also has pressure gauge 47 and liquid level gauge 50.

The apparatus is so constructed that any one or more of the draw od lines leading from the dephlegmator may be cut out of the system. The apparatus permits a very considerable variation in operation of cracking processes. For example; A whole It is to be understood thatA lephlegmator may be necessary in cracking one kind of oil, and this may be accomplished by means of the present apparatus without changing or more or less reconstrueting the apparatus.

We claim as' our invention:

l. An apparatus for cracking oil, comprising a heating chamber, a coil in said chamber through which the oil passes, a Vapor chamher communicating with said coil, a plurality of vapor outlets from different parts ot said vapor chamber, and a dephlegmator in communication with each of said outlets, :i series ot' drawof lines leading from said `lephlegmators, a common header communicating with said lines, means for cutting of one oi' more of said lines and a vapor outlet from said header.

2. An apparatus for crackingr oil, comprising a heating chamber, a coil in said chamber througlh which oil is passed, a

vapor chamber communicating With the coil',

a plurality of vapor outlets from opposite ends of said vapor chamber, deplilegmatoi's communicating with said outlets, horizontally disposed drawoff'lines leading from Y said dephlegmators at different vertical paths, and a common header interposed bevapor chamber communicating with the coil,

a plurality of vapor outlets from opposite ends of said vapor chamber, dephlegmators communicating with said outlets, horizontally disposed drawo lines leading from said dephlegmators at different vertical pathsj and a common header interposed between the dephlegmators and communicating with said drawott lines from each dephlegmator, means for cutting out one-or more of said lines, a vapor outlet from said'lieader, means for maintaining a vapor pressure on the oil, means for withdrawing condensate from said drawoff lines, and means for returning condensate from each dephlegmator to the heating coil.
