STILL.

Application Bled December 16, i921. Seria-1 No. 522,848.

To all whom z't may concern.'

Be it known that'I, Ronn'r H. LINDSAY, citizen of the United States, residing at Houston, in the county of Harris and State Vof Texas, Vhave invented certain new and useful Improvements in a Still, of which the, following is a specification.

This invention relates to new, and useful limprovexnents in a still.

One object ofthewinvention is to'provide an apparatus of the character described whielrhas been speciallydesigned for the treatment of crude petroleum, whereby the lighter elements may be readily separated from the heavier.

Another object of the invention is to provide an apparatus of this character whereinv the residuum, remaining after the` separation of the-lighter elements therefrom, will also he rendered lighter' and easier handled and ot' greater utility.

. W ith the ahove and other objects in view the invention has particular relation torertain novel features ot construction, arrangement oi parts and use an example of which is given in this specitication and illustrated iu the accompanying drawings 4whereinz Figure l shows a side elevation 'of the apparatns` showing the furnace walls in section, and, t

Figure 2 is an end view ot' the apparatus. Referring now more particular y to the drawings, the numeral l designates' an enclosing furnace, whose wall may be formed ot brick, concrete or other-suitable material. )Juive this furnace there is located a tank 'l which contains the oil to he treated. lieading t'roin the hottoni ot' this tank there is a down pipev 3 which is controlled hy .the

gate alve l and whose lower end is connected into the T-section 5, .by ine-ans ot which it is connected to the pipes (i. These latter are arranged in zigzag turns 2 iu vertical plane, within the t'urnac and at the other end thereof they are connected into a tubular pipe -S through which the residnuni is discharged.

VAbove the furnace there is arranged the outlet line 94 and the alternate coils are connected into this line through 'thev tubes 10.

'lhe oil to lie'treated circulates through the turns in the. direction indicated hy arrows iu Figure l` the lighter elements passq ing up through the tute lt) into the line l), and the residuuni passing oil' through the pipe S.

Underneath the turnsl are the pneumatic pressure lines ll. .ll` which are connected to a suitahle pressure line 1:5. The pressure lines ll are provided with the opstanding nozzles tti which are Iitted through the stull ing boxes ll otf :i'ltcin:ite .sections ot the turns T and ahove said nozzles these coil sections are restricted. as at l5.

The lui-nace is equipped with a suitable oil luu'ner lt which is supplied with fuel through'the line lT and which is connected to the air pressure line l2, through the tubular connection 1S. The lau-ner is arranged underneath the coils and heats them.

A\s the oil to he. treated circuit-ttes through the coils it is broken up by the air jets from the. nozzles 13 and the lighter elements are separated from the heavier and pass into vthe line. 9 whilethe residuuni is taken otf through tlie pipe'S above'stated.

\Vhat I' claimed is:v

A still including alfurnace, a tank above the furnace, a pipeleading from the bottom ot' the tank, and t'orined into zig-zag turns l'viug in a vertical plane. within the Furnace and terminating in a discharge outlet,"an outlet lineA 4arranged ahove the furnace, a pneumatic pressure line beneath the turns of said pipe, opstanding nozzles connected into the pressure line, said nozzles extending into the lower ends of alternative turns o? said pipe, and` disposed to discharge pressure tluid into said turns with theeurrent of Huid llowingthrough said pipe, said turns beingy restricted above the respective nozzles, tubes connecting the turns, which said nozzles exii lter, into said outlet line.

In testimony whereof I have 'signed my naine.

ROBERT H. LINDSAY.
