Patented Sept. 19, 1933 oN 'rED STATES METHOD AND APPARATUS FOR 'PRoPoR- TIONALLY MIXING A PETROLEUM 011. WITH A LIQUID REAGENT Wright w. Gary, Los Angeles, Calif. Application January'fi, 1930. Serial No. 418,816 4 Claims. (01. 196-45) My invention relates to an apparatus for proportionally mixing fluids, such as liquids with liquids and gases with liquids, and for accomplishing it with reasonable accuracy.

5 The proper proportioning of oil and acid inthe treatment'of petroleum is important for two reasons, First, when treating in a continuous system, if the acid is not uniformly applied, pe'' trollable, for varying discharge pressures from the pump give varying flow through the control valve.

Even the orifice meter is not an accurate measure of flow, due to foreign matter varying the orifice. This also effects the efiiciency of a control valve and constant adjustment is necessary and this results in flow fluctuations. I I

I have, invented an apparatus by means of which liquids can be mixed with liquids, and liquids can be mixed with gases continuously andaccurately and the proportions can be controlled as to de 39 sired percentages without the aid of adirect feed pump. As an example, if an oilis being charged to a treating unit by means of. a pump or by pressure, no direct pump or pressure will be required upon the acid in order to properly proportion and feed it into the treating unit.-

The principle on which my invention is based may be briefly stated as follows:

If one of two commodities being proportioned is being charged to the apparatus under pressure through an ejector or Venturi tube, another commodity can be forced into the apparatus by the power set up by the ejector or Venturi tube, and if the flow of the commodity under pressure is constant, the power of the ejector or Venturi tube is also constant, and the flow of the secondcommodity will be constant provided its differential head with reference to the ejector is constant. .By means of my invention I am able to'regulate this head and thus to change the desired percentage of the second commodity.

In order to more fully explain my invention,

I have illustrated a simple outline of apparatus in which the invention is embodied and which'I will now describe.

5 Figure 1 is a vertical sectional view through an apparatus embodying my invention; and Figure 2 shows an example of an operating chart. Referring in detail to the drawing, the acid supply, or the supplyof any fluid, to be mixed With another liquid or fluid, isfrom a tank or reservoir 5, which can be of anysuitable size and PATENT oFFI E material, depending uponthe fluid used, with a pp y pipe 6, and a control valve '7, with op'erating-fioat 8, for maintaining a deflniteor predetermined level of the fluid in the supply'resei voir 5. 'Said reservoir is also shownasprovided With an. outside level gauge 9 for indicating the level in inches.

From said reservoir 5 extends a flow pipe 10, j

connectedwith three vertical risers, 11, 12 and 13, each provided witha control valve, as 11',

12 and 13', forcontrolling the supply of the fluid with which the mixture'is Kto be'made.

These risers connect at theirupper ends with a common pipe 14,=connectedr with the receiving tank or reservoir 15. Control valves 11?, l2 and 13 are also connected into said risers, as clearly.

illustrated. Said risers arein the form of Ven; turi tubes,'having the restricted passages at '16, 1'7 and 1 8.

Withineach of said risers 11, 12 and 13, dise charge pipes or

nozzles

19, 20 and 21 are placed, as indicated, connected with the flow pipe 10,

whereby'the fluid to be mixed with the second fluid flows up into the said nozzles 19, 2 0 and 21 tothefluid. level of the reservoir 5, as indicated.*-

In theoperationof the apparatus, the level of the fluid in thetank or reservoirfi. is maintained and controlled by the float controlled valve .7 and this level is also maintained in the discharge nozzles, as indicated in 19, which is shown in sec- 7 In the treatment of petroleum with sulfuric acid, the oil is pumped to the treating unit under pressure, as through the vertical risers 11, 12 or" 13, as may be desired, one or more at a time, through pipe 14 into the tank 15. Inthe showing made for descriptive purposes, the sulphuric acid is supplied through the nozzles 19,

20 and 21, from the supply reservoir 5, and the level is maintained according to the adjustment of the float valve and float connection, said level being indicated by the line L. The level is indicated in inches on the gauge 9, as before referred to and the predetermined level in the reservoir 5 regulates or controls the amount of acid or other fluid taken into and up through the vertical risers by the forced flow of petroleum, or other fluid being forced into the receiving tank 15 If, for example, so many barrels of petroleum are being forced through the supply pipes or risers 11, 12 and 13, and pipe 14, into said receiving tank 15, per hour, the amount of acid entrained and carried therewith into said tank 15 will depend upon the levelof the acid. in said Ifa largevclume of petroleum .is being forced through the pipes 11, 12 and 13, to the receiving or mixing tank 15, the flow will be uniform, but should it vary slightly, the power of theejector varies accordingly and the entraining action also varies, and the amount of acid carried into the main flow is thereby automatically controlled by reason of the automatic maintenance of a predetermined level. The arrangement shown for explanatory purposes is simple and practical and I there is nothing to clog or to'get out of order.

While I have shown a plurality of risers or supply pipes for one fluid under pressure and these are shown connected in multiple, it will be under- .stood that other connections and other arrangements can be used according to the requirement and that plural connections can bev made for the fluid or fluids which are to be mixed proportionally with any given fluid being supplied under pressure to the receiving tank. It will also be understood that any type of ejector, jet pump, Sprengle pump or other arrangement Wherebythe forced flow of one fluid can entrain another fluid can be used, and that any means for maintaining a predetermined or constant level of fluid to be so entrained can be used and comes within the scope of my'invention; I do not therefore, limitmy invention to the showing made, except as I may be limited bythe hereto appended claims.
