e it known that l, SAMUEL D. l eusr 2t citizen of the United residing Pittsburgh in the county of it "heroy and ironic. have iuren d certain new and useful improvements in .rlpperetus for the Distillation or Gil of which. the following is s specificstirui,-

My invention. relates to apparatus for ids and pm. oiloperators ticularly to thermometric wherein measured heat to scparote gasolene, naphtha and similar distillutcs from heavy oil in which they be out or to which they have b en added; and

some of the objects of tl are to produce an apparatus or this general cher- 'iicter which will be simple and cheap in con struction-und at the some time ctlicicut in operation.

Another and a principal object of the vention is to provide means within the pipes carrying the oil to heat s ud superluect py steam or hot air, the circulating oil and its distillates.

l cure the separation of the light distilletes Without darkening the heery oil. and to ac complish this by c continuous op ration and by which any desired l and degree of host may be main the entire separator Ir he form degree or to 5 sc of heat in different portions sepui parts throughout the drawings;

Referring to the eggs in i let the the stented 18, 11%261.

reieren e character 10 designate e tank of any well known construction, open at the to adapted for use as u receptacle for the oil or product tobe treated It may be connectcd to any suitable source of supply. 11 denotes the usual type of a duplex, or other suitable, high pressure pump operatively connected to u boiler 12 by means of the steam line 13, provided with the necessary couplings for the purpose. Said pump 11 has the suction pipe connection 1% with the ulr 10 in order to force the product thereuroniv An outlet pipe or conduit 15 extends from said pump 11 and connects at the point 15, as illustrated, with the lowest unit of coiled. pipes 16, being provided with the proper couplings for the purpose.

Pipes or retorts l6 and 16 are arranged on a horizontal plane, one above the other, to iorm an upper and lower coil, of four pipes each, designated by the characters a and 7) respectively, as illustrated, the two coils being continuous as each individual pipe is continuously-connccted.

fit the point 17 the product passes out of the upper coil 6 into a conduii 18 which is secured, substantially to the center, of a cross arm conduit or pipe 19; by means of the coupling 20. Each end of arm 19 enters an expansion tank or drum Qi by means of the lfs 22 and 22 through apertures provided in the upper part thereof.

llelcasin r valves 32 and 33 are secured in the conduit arm 19 releasing into the spray valves 34 and 35 controlling the exit into the drum 21 These spray valves 3%":1nd 35 are constructed us particularly illustrated in Fig. 4, having the tapering elongated spray nozzlcs 36. Outlets 37 and 38 are provided in the upper portion 01" the drum 2-1 as shown. Vapor discharge pipes 39 and 40 are connect l thereto and lead to :1 condenser 1-2. generated ll) the boiler 12 passes mler pressure therefrom through the steam line 23. This steam pipe or line 23 at the point 523 is reduced so as to pass through and within the various pipes comprising the lower coil (1 as indicated by dotted lines in l? 1 and utter passing through said lower coil 16 is returned to the product tank 10 through at coil 10' in said tank 10, so that said tank.

this exhaust steam may be utilized to heat Said'coil terminatesin the waste outlet 10 The U shaped connections 24 are provided at the turns of the units comprising the coils a and b to permit of the steam 0117- culating at these turns without interfering with the passage of the product through said coils, and are provided with the stuffing boxes having the glands 26 to be made tight by proper packing. V This construction is particularly illustrated in Fig. 3 of the drawings.

28 denotes a super heater, of any well known construction, having the connection 29 with the steam line 23. A valve 30 is provided therein to control the flow of steam to said heater 28. An outlet pipe or steam line 31 extends upwardly from said heater 2-8 and enters at the point 17 into the topmost unit of the pipes 16 comprising the upper coil 7) and extends downwardly through said coil 11 in the same manner and with the same couplings and connections as the steam, line. 23 is extended upwardly through the lowcrcoil a, as hereinbefore described. After leaving the coil 7) said line 31 may extend out into the open as illustrated, or it may be continued so as to he.

returned to the product tank 10, if desired.

The super hcatcr 28 has therein a coil 29' discharging into the steam line 31. This coil 28' is'luu'e illustrated coiling horizontally within said heater but may be arranged to coil vertically.

, Pet cocks 21 are provided as shown to a drain the steam lines 93 and 31'when requisite.

In opcration, the product from the tank or'reccptacle 10 is forced by means of the pump 11 through the conduit 15 and through the pipe units comprising the lower coil a and upper coil 7).

\Vhilc the product is thus being pumped through the lower coil (t it is subjected to the steam from the boiler 12 passing through thc pipcs 2?) within the coil a. in

practice l ha \c i'ound it expedient to use a three inch pipe l'or the product and a one inch pipc therein for the steam: When the product has passed through the lower coil o and has been subjected to the heat from thi v steam pipes 23 as hcreinbefore described the product has become what may he termed saturated vapor and fractional distillation has taken place 'As thissaturuted vapor -o ntinucs its upward travel through the pipe units comprising the upper coil 7). it is subjected .to a still higher degree of heat,

than it was when passing through the lower end (1 from the steam p pes 31 arranged within the coil 7) and is therefore i I super heated while passing through the coil 71.

Fireis appliedto the super heater, in addition to whatever heat the steam may obtain from the boiler 12, to generate whatever predetermined degreeof heat that may he requisite to causea more complete fractional distillation of the product, It will be noted that thegreatest degree of heat is applied to the product at the point 17 as said product is leaving the upmost pipe unit of the upper coil 1). -This effectual y prevents the product, after having been distilled or "cracked 0., the molecules comprising the product having been broken up from returning to its former state or coagulating. A pyrometer 48 is secured to the steam line 31 as illustrated in order to ascertain, substantially, the highest degree of heatapplied to theproduct. The tem-.

perature employed in the lower coil a is from 25' tofiillo. degrees Fah. and in the upper coil I; from 500 to (300 degrees Fah..

The product now distilled and in the form of vapor passes out of the upper coil 5 into a conduit 18 and a crossarm conduit,

secured thereto, 19. A pressure gage '18 is r positioned in the conduit 18 as shown.;

At a predetermined pressure, say 300 lbs.,

the releasing valves 32 and 33, being 'set for such pressure, open and permit the ,vapor to enter the spray valves 34 and 35, which are normally open. Thesespray Valves 34 and 35, as herelubefore described, are pro-.

vided with the elongated spray nozzles 36, so that the vapor under theabove pressure is sprayed into the drum 21 and against the.

inner walls thereof, whereby the carbon'zand heavy gravitysubstances precipitate to the bottom of said drum 21, while .tlieli hter gravities and vapor pass by'means 0 and 40 into a condensing coil 41, submerged outlets ,3? and 38 and discharge pipes 59 1105 in water-,in a'condenser 42 having the out lot 43 to any desired receptacle. The carbon or other solidsprecipitated to the bottom of the drurn'2l may be withdrawn therefrom through the man hole 44 provided in the bottom of said drum and the heavy gravities may be likewise withdrawn from said drum 21 through the outlet in the bottom thereof controlled by the valve 46V It will he noted that the outlets 37 and 38 are preferably located in the upper porlion of the drum 21 in order to provide more modifications of ed, before distillation, with a catalyzerl, if desired; "the ei'iect being to facilitate the breaking up of the molecules comprising theproduc I find that the carbon in the not precipitate while the product is in inotion therefore I obviate the possibilit of the pipes 16 and 16 becoming clogged with carbon from the product passing there through, as my apparatus provides for a continuous circulation of the product.

It is not desired to confine this invention to any particular number of sets'oi. pipes or to the arrangement thereof and the rig t is reserved to make all such changes in and the construction, "shape a d 'clesign thereof as comes within toe intion.

Having thus described my invention what I claim as new and desire to secure by etters Patent is; p
