IMPROVEMENT IN CONSTRUCTION OF APPARATUS FOR THE REDISTILLATION OF COAL-OILS.
Specification forming pari' of Letters Patent No. SJlG, dated May 15, 1860.
To @ZZ whom t may concern:
Be it known that I, LUTHER ArwooD, of the city and county of New York, and State w of New York, have invented certain new and useful Improvements in Apparatus for Distilling Volatile Oils; and I do hereby declare that the following is a full and correct description ofthe same, reference being had to the annexed drawings, making a part of this speciiication, and to the letters of reference thereon.
t The nature of my invention consists in the arrangement of a separating-chamber, in corn bination with a volatile-oil still and condenser, in manner and for purposes substantially as hereinafter described.
My said improvements are particularly designed and adapted for working a process of producing light thin hydrocarbon illuminating-oils from heavy oils, paraffine, d'c., the subject of cotemporaneous Letters Patent of the United States granted to me.
The drawings represent a distilling apparatus, the subject of prior Letters Patent of the United States to me, with the above-mentioned separatingchamber and its ad]- uncts combined therewith.
Figure No. lis a plan view of the apparatus 5 Fig. No. 2, a front elevation; Fig. No. 3, horizontal section through dotted line zr, Fig. 2; Fig. No. 4, horizontal section through dotted line y y, Fig. 2; Fig. No. 5, transverse sec` tion through dotted line zr, Fig. l; Fig. No. 6, vertical longitudinal section through dotted line i/ y, Fig. l.
Letter A represents a cast-iron still suitable for distilling volatile oils, set in brick-work, and provided with furnace, Ste., for heating man-holes and filling-pipes; also,with a safetyvalve, B, connecting by a blow-off pipe with the main c and exit-pipe D.
E is an angle-valve connecting the dome of the still directly with the wornrcondenser by the pipe F. rIhis angle-valve E must be closed when the separating-chamber is used.
Letter G represents a vertical chamber or receiver, which I call a separating-chamber, its office being to receive the vapors from the still and contain them while the lighter bodies separate from the heavier' by difference of temperature and specific gravity. The height of the separating-chamber is about four times its diameter. It is composed of a number of short cast-iron cylinders secured together by flanges and screw-bolts, and made tight with suitable packing or cement. At top and bottom are heads secured to the ends by flanges and screwbolts. The bottom or base of this chamber rests on a cylindrical pier of brick-work built up from the wall or casing of the still sufficiently high to sustain the base of the chamber at an elevation a little above the top of the dome of the still.
Letter H is an angle-valve on the dome of the still, connecting the still with the separating-chamber by the superior pipe I at the side and near the bottom of the chamber.
J is an inferior pipe provided with a stopcock, connecting the bottom of the separator with the still.
K is a pipe connecting the top part of the separating-chamber with the pipe F, leading to the worm-condenser. The pipe K is furnished with astop-cock, which is to be closed when the still is used withtheseparating-chaniber shut off, to prevent gas, cc., from backing up into it.
L is a steampipe, shown broken off, but io be connected with a steam-boiler, and by means of a -i-coupling to supply steam, when required, to the body of the still through the pipe M to the condenser when the angle-valve E is closed by the pipe N, and to the separating-chamber and its passages by the pipe O.
The operation of the apparatus is as follows: The heavy oil is placed in the still, the manA holes secured and luted, the flling-pipes, safety-valve, and angle-valve E closed, and the connections between the still and separatingchamber, and from thence to the worm-conl denser, opened. Sufficient external heat is applied to the still by means of a fire in t-he furnace to form oleaginons vapors and fixed gases, which pass up to the separatingchamber. rIhe vapors so formed differ in character, a part being lighter and of a lower boiling-point than the rest, the boiling-point of the lighterbeing about GOOo Fahrenheit, and the-heavier considerably above that degree of temperature. The separating-chamber is heated only by the vapors from the still, and is exposed externally to the moderate temperature of the atmosphere of the still-room. The internal temperature is therefore below the point at which the heavier bodies can be maintained any considerable time ina state of vapor. They therefore gradually liquefy and fall to the bottom of the separating-chamber, and are returned to the still tm the inferior pipe J. The lighter bodies and permanent gases gradually rise to the top of the separating-chamber, and go over to the Worm-condenser through the pipe K. If sufficient heat be not applied to the still to form vapors with such rapidity as to keep up the heat in the separating-chamber to a point high enough to maintain the lighter bodies in a state of Vapor, so that they Will rise above the'heavy bodies and pass over to the Worm-condenser, they will of course condense and fall back to the sti-ll, and this will also be the case if the separating-chamber be placed in a situation remote from the still, and so that the vapors cool on their passage Y to it. IIf the separating-chamber be notof suiiicient capacity and height to permit of the gradual separation of the lighter from the heavier bodies, a great part of the latter Will be forced over to the Worm-condenser. The arrangement, situation, and proportion of thc separating-chamber relative to the still, as shown in thedrawings, I consider best for a still body or boiler such as gured of about seven feet in diameter. Vith such an apparatus I can run over thin oil from heavy oil at the rate of-about ten gallons per hour, con` tinually returning the heavy oil not decomposed to the further action of the heat until the contents of the still are exhausted.
Vhen desirable to clean the separatingchamber and its passages, I close the anglevalve H and admit steam from the pipe O.
When I Wish to use the still Without the sepa- I.
rating-chamber, I close the anglevalve H, the stop-cock' in the inferior pipe J, and the stopcoclr in the pipe K, and open the angle-valve E.
The sides or barrel of the separating-chamber may be one entire cylinder, if desired, the use of the short ianged sections being merely a matter of convenience, for the purpose of readily increasing or diminishing its height and capacity.
The pipe K, instead of being connected with a Worm common also to the connection from the still through the angle-valve E, may be connectedwith a separate and independent Worm iu the same or another Worm-tub, and this arrangement will be best When the still is often used Without the separating-chamber.
`I do not limit myself'to the precise form and Y proportion of the separatingcharnber herein shown; but '4 I claim as my invention- Y A separatingchamber. constructed substantially as described, when arranged and eomf bined With a volatile-oil stilland condenser in such manner as to gradually separate and condense the heavier parts of the oleaginous vapors formed and continuously return them to the still for a further action ofthe heat, and at the same time preserve the lighter vapors and pass them over to the condenser, substantially as herein described, and substantially for the purposes hereinbefore set forth.
