APPARATUS FOR S EPARATING SO LVENTS FROM OIL.
SPECIFICATION forming part of I Letters Patent No. 698,3 98, dated April 22, 1902. Application filed August 21. isoiljserai No. 72,805. (No modeL) of Illinois, have invented a certain Improved Apparatus for Separating Solvents from Oil, of which the following is a specification.
This invention is intended for use in con-i nection with the extraction of oil by the use of a hydrocarbon solvent; and its purpose is to separate the oil from the solvent after the process of extracting the oil is completed.
The invention is exemplified in the structure hereinafter described, and it is defined in the appended claims.
In the drawing forming part of this speci fication an embodiment of my invention is represented with the casing cut in central working apparatus the vertical members of vertical section.
The shell or casing l is made of any suitable size and shape. It is composed of imperforate sheet metal or the like,-and its joints are air-tight. A tank or basin,as 2, is sustained in the upper end ofthe shell in any suitable way. The top side of thebasin is open to receive the oil and solvent, and it has discharge-tubes, as 3, through which the com.
bined oil and solvent escapes. Below the basin 2 is a coil of pipe 5, the principal extensions of which are vertical.
and solvent encircling the pipe. The tubes 3 discharge the contents of the basininto the pans that encircle the pipes. The exterior surfaces of the pans taper downward to the; circumference of the pipes, and whentthe; pans overflow the oiland solvent adheres to somewhat volatile solvent from the more stable oil in the films surrounding the pipes. The vaporized solvent is held in the chamber Near the np. per ends of the vertical members of the coil are a set of pans 4, which embrace each a vertical member of the coil and are adapted tohold a small quantity of the combined-oil 1, ordinarily rising toward the top thereof,
and theoil settles in the bottom of the chamher. The pipe 7 may lead to an exhaustpump or vacuum-forming device of some kind or other, and the partial vacuum thus established tends to draw the vaporized solvent from the chamber 1. The lower end of the chamber has a discharge-pipe 8 for the oil, and such pipe has a return-bend 9 at its upper end that forms a trap in the oil and insures practically continuous closing of the end of the pipe. The oil and solvent is supplied to the basin 2 through a pipe, as 6, in the upper end of the chamber 1.
The coil 5 is shown in the drawing in a simplified form the better to illustrate the principle involved in the invention; but in a the coil will be as numerous as is consistent with the temporary storage and subsequent withdrawal of the vaporized solvent.
The specific construction shown and described is desirable, but not in all particulars indispensable, and I do not restrict myself in that regard beyond the terms of the claims.
I claim- 1. Anapparatus for separating oil from an oilextracting solvent, comprising a closed chamber, a vertical pipe in the chamber forming a passage-way for a heating medium, and means for supplying the combined oil and solventinathin 'film around the outside of the upperpart of the pipe.
2. An apparatus for separating oil from an oil-extracting solvent, comprising a closed fch'amber, a coil of pipes disposed vertically Iin, the chamber and forming a passage-way for aheating medium, and means for supplying-the combined oil and solvent in thin films around the outside of the upper parts of the pipes.
In testimony whereof-I sign my name in the presence of two subscribing witnesses.
GLEM ERIsMA-N.
