OIL AND GAS SEPARATOR.

Application filed December 17, 1924. Serial No. 758,494.

To all whom it may concern:

Be it known that I, CLARENCE J. WVoLrn, a citizen oi the United States, and a resident oi Quay, in thecounty oi Pawnee and State of Oklahoma, have invented certain new and useful Improvements in Oil and Gas Separators, oi which the tollowing'is a specification. v

lhis invention relates to a separator for gas and oil, and is especially designed for separating the gas from the oil as the cominingled gas and oil come from the well.

The object oi the invention is to provide a separator of this character designed to collect and preserve the more volatile products of the oil well and which operates to this end in a novel and eficient manner.

A still further object is to provide a separator or this character and having these advantages and which is 01 simple and durable construction, reliable and efiicient in operation and easy and comparatively inexpensive to manufacture and maintain.

Other objects and advantages of the invention reside in certain novel features of the construction, combination and arrangement of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming part oi this specification, and in which:

Figure 1 is a view in side elevation, showing one embodiment of the invention;

Figure 2 is a plan view of the separator shown in Figure 1;

Figure 3 is a view in side elevation, showing a slightly different embodiment of the invention,

Figure 4 is aview in horizontal section, taken on line 4-4 of Figure 3, and

Figures 5 and 6 aresectional views oi the couplings or connections employed for permitting the separating tanks to move relative to their supply and discharge pipes.

Referring to the drawings, and more especially to Figures 1 and 2, the numeral 10 designates a platform supported upon the upper end of a derrick 11.

A separating tank 12 is provided and is yieldably supported on the platform 10 by means of cross bars 13 secured by angle plates 14 to the lower end of the tank 12 and having their ends engaged with and secured to resilient or yieldable supports 15. The supports 15 are or identical construction and each includes telescoping cylinders 16 and l? and a coil spring 18. ihe cylinders 16 are secured to the bars 13, and the cylinders 17 are secured to the platform 10 and areslidably fitted in the'cyl' V inderslb'. The ends of the cylinders 17 and '16 are open so that the coil springs 18 engage the bars 13 at one end and the platform 10 at their other end. The coil springs 18 are tensioned to support the tank 12 in elevated position when the tank is empty and to permit the tank 10 to gradually lower as the same fills up with oil. The

cylinders

16 and 17 constrain the tank 12 to axial movement and prevent lateral displacement thereof.

Means is provided for supplying the commingled gas and oil to the upper end of the tank and comprises a number of supply pipes designated generally at 20.

l Vithin the tank 12 the oil settles to the bottom or lower end of the tank, and the gas collects at the top of the tank. A gas outlet pipe 30 leads from the top of the tank to a valve casing 31 in which a pressure controlled valve 32 is fitted. The valve 32 is held in closed position by means of an arm 23 connected to the stem 32 of the valve 32 and having a Weight 34 adjustable thereon. By adjusting the weight 34 along the arm the pressure at which the valve 32 is opened may be varied. Gas discharge lines 35 lead from the valve casing 31 to the tanks in which the gas is to be stored and to other points at which it is desired to deliver the gas.

An oil outlet or oil discharge line 40 leads from the lower end of the tank 12 and connects with a valve casing 41. The valve casing 41 connects the outlet pipe 40 with the pipe line 42 which leads to the point at which the oil is to be stored or delivered. A valve 43 is mounted in the valve casing 41 and controls the communication between provided along the tank in order that the level of the oil within the tank may be gage'd.

As the various supply and discharge lines must convey the liquids or gases to and from the tank in all positions of the tank each of the lines must have suitable devices embodied therein to give the same the req uisite flexibility. Flexible pipe sections and flexible and universal couplings are in corporated in each line to accomplish this purpose. Preferably, however, each line has a tl-shaped pipe section embodied therein, one leg 60 of each U-shaped section being connected to a flexible or swivel coupling 61 and the other leg 6O being connected to a flexible or swivel coupling 62. The axes of the, couplings 61 and 62 are horizontal and parallel.

As shown in Figure 6, each coupling (31 COl'llpllSGS a casing 65 having one end connected, as at 66, with the supply line in which it is embodied T he opposite end of the casing is open and receives the leg 60 of the U-shaped pipe 60 associated therewith; A number of coils of garlock packing 67 encircles the portionof the leg 60 located within the housing and this packing is compressed betweena shoulder 68 thread ed into the casing 65 and a follower 69 con trolled by stud bolts 70 and nuts 71 co-acting with a flange 72 on the follower. A ring nut 73 may be threaded on the leg 60'" to prevent its accidental displacement from the housing.

As shown in Figure 5 each coupling 62 comprises an externally threaded cylindrical casing 75 suitably connected to the line .in which it is embodied and receiving the flangedend T6 of the leg 60 of the U-shaped pipe 60 associated therewith. A number of coils of garlock packing 77 encircles the pipe leg 60 and is compressed between a shoulder 78 threadedly connected to the casing 75 and a followerlfi) controlled from a cap 80 having internal threads engaged with the threads of the casing 75.

lVith this arrangement the angular relation of the

legs

60 and 60 with respect to their couplings may vary and this together withthc resiliency of the various lines perniits the tank to move freely up and down.

lVith this arrangement as the weight of the oil increases in the tank 12, the tank 12 settles or lowers as the springs 18'compress due to the increase in weight which follows upon an accumulation of oil in the tank 12. The downward movement of the tank 12 is transmitted to the valve 4.3 through. the bracket set screw -16 and stem at so that the valve 13 is opened to permit the discharge of oil from the bottom of the tank. \Vhen suflicient oil has been discharged from the tank 12 the tank 12 is again elevated by the springs 18, and consequently the valve a predetermined point, the valve 82 is automatically opened to permit the gas to flow to the storage tanks or to the points at which gas is to be delivered.

The embodiment illustrated in Figure 3 and 4. is identical with that shown in Figures 1 and 2 and the description hereinafter applies thereto with the exception that the tank 12 is somewhat smaller and in lieu of being arranged on a platform on the upper end of a derrick, the tank 12 in F igurcs 3 and 4; is supported on the top of a large storage tank for the oil, the storage tank being designated at 91. lVith the arrangement shown in Figures 3 and l means is provided to supplement the action of the supports in constraining the tank to axial n'iovement, and this means may comprise a plurality of standards 92 clamped to the tank 91, by hoops 9-3 and connected to each other by adjustable links 945 to the tank 12 by means of adjustable links 95 and a band 526 encircling the tank adjacent its upper end. The links 95 are pivotally connected to the band 96 as at 97.

I claim:

A separator for gas and oil comprising a tank, means for yieldably supporting the tank and comprising a stationary structure cross bars connected to the tank, and yieldable supports between the cross bars and the stationary structure, said yieldable supports comprising telescoping cylinders and coil springs within the cylinders and engaging the stationary structure and the cross bars; flexible supply lines conveying commingled gas and oil to the tank, a pressure controlled gas outlet leading from the upper part of the tank, an outlet for the oil leading from the lower part of the tank, a valvecontrolling said outlet, and motion transmission means between tne tank and the valve for opening the valve as the tank moves downwardly and closing the valve as the tank moves upwardly.
