APPARATUS FOR DISTILLING HYDROCARBOS Patented May 25, 192e.
MIION J. TBUMBL, OF LOS ANGELES, CALIFORNIA.
APPARATUS FOR DISTILLIN G HYDROCARBONS.
Application filed April 16, 1923. Serial No. 632,287. -1
' This inventionrelates to the art of re. lining petroleum oils and relates particularly to an improved equipment for use in distilling light hydro-carbon constituents from crude petroleum oils. The process with which the hereinafter described apparatus is employed is fully set forth in my application, covering a refinery power plant,
' filed December` 1, 1922, Serial No. 604,301.
In this refining process, the oil is raised to the temperature at which the hydrocarbon desired to be removed volatilizes, and is directed into a separator consisting of a chamber in which the volatile characters rise from the oil and are carried to a mechanical device, such asa turbine in which the heat of expansion of the gases is transformed into mechanical energy. In order that the pressure apparent atthe turbine be kept constant, the process provides for the introduction of super-heated steam,
which sustains the pressure in the system as well as maintains the required temperature to prevent premature condensation of the distilled constituents. l
By the use of this process, a great saving is accomplished through the employment of the power, represented in the heat used to volatilize the hydro-carbon, for .the purpose of driving a mechanical device. The prime mover employed is preferably a turbine and 'it 1s convenient to directly connect an electro-generator therewith, whereby the mechanical energy derived from the heat is transformed into electrical energy, which may be conducted to various points for use.
It is an object of my invention to ,provide a simplified form of apparatus for practising the' hereinabove described process.
It is a further object of the invention to provide in this equipment, a means for spreading the heated oilin the form of a thin film from which the volatiles may readily separate.
It is a further object of the invention to incorporate in the separator employed therein, means for extracting from the volatilized constituents any heavy hydro-carbons which may be carried therewith.
The especial advantages of the invention and further objects thereof will be made evident hereinafter.
. In the drawin which is a diagrammatic representation o? an apparatus embodying the features of my invention, 1 represents the pump cylinder of a steam pump, or other pumping device, which receives oil through an oil delivery pipe 2 and drives it through piping 3 into a heat interchanger 4 wherein its temperature is raised by being brought into proximity with heated oil being discharged from the apparatus, as will hereinafter be described. The oil is delivered from the heat interchanger 4 through a piping 5, which leads into a furnace or retort 6, wherein the temperature of the oil is raised to a still higher degree. Through an interconnecting pipe 7, the oil passes through a second retort 8 from which it is directed through piping 9 into a distributor ring 10,y situated within a separator or vaporizer 11. The distributor ring 10 rests in a circular channel 14 which is enclosed between the side wall 15 of the separator 11 and an annular member 16, having a fairly deep cylindrical wall 17.
The distributor ring 10 has downwardly directed outlet openings 18 in the under side thereof and is placed somewhat above the bottom 19 of the annular member 16. The oil which is spread into the channel 14 from the ring 10 often contains considerable quantities of sand, which is very sharp and abrasive. By placing the ring away from the bottom 19, space is left under the ring for the collection of sand, which provides a cushion against which sand carried in the oil strikes and is thus prevented from contact with the bottom 19. In this manner, the bottom 19, is relieved of wear which would occur if the sharp particles of sand were allowed to come continuously in conl tact therewith.
The oil upon entering the channel 14' rises at an .even llevel continuously therearound,
,and reaching the upper edge of the cylindrical plate 17 flows downwardly in a thin film on th'e inner face of this plate 17. The reducing of the oil to a thin film in( this manner, permits` the volatile constituents to readily separate from the film ofoil which flows down and collects in the bottom of the separatorll, as indicated at 20.
A float 21 is mounted upon an arm 22, which is associated through-ea pivot 23 with an external arml 24. This external arm 24 is connected by a llink 25 to the operating lever 26 of a valve 27, situated in the residuum discharge piping 29. As the level of the body of oil 20 contained in the separator 11 liftsthe fioat, the valve 27 is opened by the interconnecting link mechanism and allows the hot residuum oil to iow through the piping 29V into`the heat interchanger, where a greater portion of the heat thereof `is transferred to the'incoming unrefined oil delivered into c the interchanger b the pump 1. It will be recognized that with the float-and valve arrangement, a self operating -rator through the pipe 9. In the upper portion ofthe separator 11 interceptor plates 31 and 32 are situated. The plates 32 are annular in shape and have lipped openings zoA 33 in the center thereof. The plates 31 are of decreased diameter and are interposed between the plates 32. The gases in seeking the outlet 35 must pass around the plates 31 and 32 in a tortuous path as indicated by the arrows 36.
The cross sectional area of the spaces between the plates 31 and 32 is many times -larger than the cross sectional area of the outlet 35, therefore the gases will'pass between the plates at a comparatively slows, rate of speed, and coming in contact with the faces thereof, will be relieved of all heav oil constituents which may be carried wit the volatiles desired to 'be separated. The outlet 35 leads into a pressure regulator 38, which connects through piping l39 with a prime mover 40 having connection through pipe 41 with a condensor 42. The prime mover 40 may preferably consist of a vapor turbine, and it is desirable to employ this turbine to drive a dynamo so that the power represented by the -expansive heat contained in the vapors directed to the turbine may be transformed into electrical energy.
In the distillation of light hydro-carbons from crude oil, the pressure wlthin the aparatus varies greatly at different periods, (Pine to the change in the light hydro-carbon carried in the various vportions of oil being treatedand also to the 'change of temperaso. ture in the equipment. invention, however, employs a means for delivering steam under pressure into the apparatus, this steam serving to stabilize the pressure within the separator, andto sustain the heat therein.
The power value of the steam is reclaimed at the prime mover 40 in other words it is transformed into electrical energy. This steam is generated at a boiler 45, having a delivery pipe 46 leading therefrom into a superheater 47. From the superheaterA 47, the steam is carried through piping 48, having valve means 49therein Ito a distributor ring 50 situated in the bottom of the separator 11. From the pipe 46, delivery piping 52 provided with 'a valve 53 is carried to a pressure regulating valve 54, Which associates through a pipe 55 with the. interior of the separator 11.` When the pressure within the separator 11 liuctuates downpipe 7 between the retorts 6 and 8.
In the manner previously described, a substantially evenpressure may be maintained at all times within the apparatus, notWithstanding some variation in temperature therem and a constant generatlon of power at the prime mover is effected. The`v power represented in the heat used for generating the steam is reclaimed at the prime mover- 40,-and by the use of this steam is made possible the reclamation of the heat contained in the volatiles, which heat has heretofore been dissipated by the use of large quantities of cold water.
