IMPROVED PROCESS FOR TREATING PETROLEUM.

Specification forming part of Letters Patent No. 67,796, dated August 13, 1867.

To all whom it may concern:

Be it known that I, JOHN G. PEDRIGK, of the city of Washington, in the District of Columbia, have invented a certain new and Improved Process for Treating Petroleum, Naphtha, and other liquids and substances of that class; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters and marks thereon, which said drawings form part of this specification, and represent an apparatus or one arrangement of means for the carrying out of my invention.

The apparatus here shown consists of a steam-generator, a, an oil-reservoir, b, a hydrocarbureter, c, and a condensing-chamber, d.

Figure 1 of these drawings is a vertical sectional view through the generator 0,, the steam and air pipe, and the oil-reservoir I), and a view of the condensing-cylinder d. Fig. 2 is a top View of the apparatus as a whole. Fig. 3 is a View by vertical section of the carbureter c and the condensing chamber or cylinder d. Fig. 4 is a side view of the apparatus; and Figs. 5 and 6, views by section in their length of the steam and air conducting pipes.

In each of these figures, where like parts are shown, like marks and letters are used to designate the parts.

My invention has for its main object the vaporizin g or generating of gas from the heavier coal-oils orhydrocarbon's, and the combining with such vapor or gas moist atmospheric air for illuminating and other purposes, the atmospheric air being carried forward into and distributed through the oil or hydrocarbon by a current of steam.

- Any suitable steam-generator, a, may be used, from which the steam can be conveyed through a steam -pipe, 0. If the end of the steam-pipe passes into the funnel f of another pipe, 9, the current of steam will carry along with it a current of air or, if the end of the tube or pipe 9 be perforated and a sliding tube be used, as shown by Fig. 1, or the arrangement of the tubes or pipes as shown by Figs. 5 or 6 be used, steam may be introduced alone, or steam and air, as may be required.

The air and steam will pass down the pipe g, and through the perforated cone it into and up through the oil contained in the reservoir D. From b, through thepipe t, the combined vapor or gas and air will pass out, either directto the condensing-chamber d or first through the carbureter c, where the vapor from a light carburetin g material may be united with the former or not, as may be required for the special pur pose desired. In some cases purifiers can be placed in the chambers of the condensingchambers d, and around the carburetor a, in the annular recess j, either hot or cold water may be placed for equalizing and giving uniformity to the gas. I

Whenever it is desirable to heat up the oil or material in the reservoir 1) previous to the introduction of the air, it may be done by passing steam through the coiled tube k; or it may be done by the arrangement of the pipes e and g, as before described.

As is evident, other means and arrangement of means may be used for introducing the steam and air into and through the oil or material in the cylinder or reservoir b, and the sources of the air and steam may be independent, and the two be brought together in the oil or reservoir; or the one or the other, the steam or the air, may first be introduced and then the other. Instead of the steam-generator herein alluded to for furnishing the steam, in some instances the exhaust-steam from an engine may have sufficient force and power to be substitutedtherefor.

The passing of steam and air through petroleum, or the other substances herein named or alluded to, necessarily removes the lighter or .more volatile elements or qualities to a greater or lesser degree, due to the temperature of the steam and air, and the oil or hydrocarbon then remaining, being freed from these elements, is therefore rendered a safer and more useful article for common lamps or lights and for consumption as a fuel; and in case the oxygen of the water that Will set free a porcurrent or currents of steam and air, substantion of the hydrogen, which may be made tially as and for the purposes herein set'forth. available for the generation of a more intense This specification signed this 29th day of heat when desired; also, that the condensed July, 1867.

q id may be made useful.

What I claim as my invention, and desire JOHN PEDRIOK' to secure by Letters Patent, is- Witnes Treating petroleum or other hydrocarbons THos. 'l. EVERETT,

by passing through the oil orhydrocarbon a 1. SMITH.
