METHOD OF EXTRACTING PARAFFINE OR OTHER BODIES FROM PETROLEUM.
SPECIFICATION forming part of Letters Patent No. 369,902, dated September 13, v1887.
Application filed April 11, 1887. Serial No. 234,384. (No model.)
.To all whom, it may concern.-
Be it known that we, GEORGE AAB and SANFORD K. CAMPBELL, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Methods for Extracting Paraffine or other Bodies from Petroleum; and we do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawing, which forms part of this specification, in which the figure shows one form of apparatus by which our process may be practiced.
This invention has relation to a method or process for extracting paraffine and other solid matters from crude or refi'ued.petroleum.
Crude petroleum contains from five to forty per cent. of paraffine or other solid matter, the percentage varying in different oils, but usually averaging about twenty-five per cent.
Refined petroleum contains from one to three per cent. of parafliu'e. The smaller the quantity the better illuminating qualities possessed by the oil.
The several different processes most generally practiced for refining the oil have the same objection. They do not extract all the parafiine, and those processes that do extract the larger quantities are slow and expensive.
The object of this invention is therefore to extract paraffine and other solid bodies not alone from crude petroleum, but from petroleums that have been refined by the usual and well-known'methods.
Our invention therefore consists in the combination,with an apparatus for extracting solid matters from oil, of a strainer coated or saturated with paraffine.
Incarrying our invention into practical operation we do not wish to confine ourselves to any special mechanism, as the same may be carried out in avariety ofways, oneof which is illustrated in the accompanying drawing, in which-- A represents a cylindrical vessel, preferably made of cast metal, which is suitably mounted, and provided with means for rotat ing the same at a high speed.
B is an interior vesseLprovided with numerous perforations, b b, &c.
C is a lining for the interior "essel, and is preferably made of a heavy closelywoven material, such as canvas.
D is a lid for the vessel A, and a is a cock by which the contents may be withdrawn.
The operation of the process is as follows: The cloth C is soaked in or coated with paraffine. Crude or refined petroleum is then placed in the interior vessel in any desired quantity, the cloth C preventing its escape through the'perforations' into the outer vessel, A. Power is then applied, and the vessels are rotated at from one thousand to four thousand revolutions a' minute. The centrifugal force exerted by or rotary motion upon the body of the oil will cause the lighter portions to pass'through the cloth C and perforated vessel B, while the para'lfine and other solids will be retained withinv the vessel, being generally found attached to the cloth C, from which they can be readily removed. Actual experiments have shown that over one per cent. of paraffine has been extracted from the very best oils as refined by the ordinary methods.
XVhile we have described centrifugal force as applied for throwing the petroleum against or through the cloth, we do not wish to confine ourselves to that precise force,as we may use rotary motion within the body of the petroleum. For instance, we may use a stationary tank supplied with a revolving dasher or screw, which will throw the petroleum from the center to the sides of the tank.
What we claim as new is The method of extracting paraffine or other bodies from petroleum, which consists in forcing the petroleum through a cloth previously coated or impregnated with paraffine,whereby the paraffine or other solids contained within the oil will be separated therefrom.
In testimony that we claim the foregoing We have hereunto set our hands this 2d day of April, 1887.
GEORGE AAB. SANFORD K. CAMPBELL.
