PROCESS OF TREA'ING HYDROCARBONS.

Application led September 17, 1917. Serial No. 191,802.

To all whom it may concern:

Be it known -vthat I, GUsTAv EGLOFE, a citizen of the United States, residing in the city of New York, county of New York, and State of New York, have invented certain new and useful Improvements in Processes of Treating Hydrocarbons, of which the following is'a specification.

This invention relates to improvements in process of treating hydrocarbons and has as its salient object the heating of the hydrocarbons by suitable electrica-l resistance material submerged in the body of oil in the still. During such heating the oil is dis-- tilled under pressure.

In the drawing is shown a more'or less diagrammatic view of an apparatus suitable for carrying out my invention.

Referring to the drawing, 1 designates a furnace having an oil or gas combustion chamber 2 and stack 3. In this furnace is seated a horizontal. still 4. The furnace is used to externally heat the still merely for the purpose of raising the temperature of the Oil reliminarily to a distilling temperature. n the still is suitably supported a suitable electrical resistance material 5, which mightv be carbon, nichrome material or other suitable electrical resistance. This electrical resistance material is connected to a suitable source of electrical energy by the conductors 6 and 7. rPhe vapors p-ass out of the still in a vertical dephlegmating column or tower 8. This tower is connected to an inclined reflux condenser pipe 9, which connects through gooseneck 10 to an expansion chamber 11, having valve 26 and sightglass 25 attached. The expansion chamber 11 is connected at its upper end to a pipe 12 leading to a condenser coil 13 seated in water tank 14E. The lower end of the coil 13 connectszto the upper end of a receiving chamber or tank 15. The drawoff pipe l16 leads from the lower end of the receiving chamber and is controlled by throttle valve 17. A gauge glass 18, pressure gauge 19 and gas valve 20 are also connected to the receiving chamber. The still is provided with pressure gauge 21, safety valve (not shown) and pyrometers l22 and 23 as shown on they drawing. A valve 24 is interposed in the reflux pipe 9 between the still and the condensing side ofy the system. The arrangement is such that pressure is maintained on the still and reflux condenser, but not on the expansion chamber and water condenser.

One of the main advantages of the use of the electrical resistance material is to obtain a very accurate temperature control. It has temperature may vary from 4000 to 1,0000

F. and the pressure from -20 to 200 pounds, or more. A suitable oil temperature may be 750O F. in treating mid-continent gas oil and a pressure of 110 lbs. will be satisfactory to convert 30% or more gas oil into gasoline.

The invention is not limited to the details of process shown, except as Set forth in the appended claims.

I claim as my invention:

1. A process of treating hydrocarbons to convert heavy into lighter hydrocarbons which consists in'raising the oil to a Adistilling temperature, by suitable heating means while maintaining the oil in a substantial body and then carrying the process out by heating the oil with an electrical resistance material immersed in the body of the oil and during the treatment maintaining a pressure' in excess of 20 lbs. to the square inch during distillation.

2. A rocess of treating hydrocarbons to convert eavy into lighter hydrocarbons consisting in externally heating the oil maintained in a substantial body to a distilling temperature, continuing the conversion by internally heating the oil body by an electrical resista-nce unit, confining a percentage of the`generated vapors above the oil body -for maintaining a regulated vapor pressure in excess of twenty pounds to the square inch upon the oil during treatment.

3. A process of treating hydrocarbon to convert heavy into lighter hydrocarbons consisting in heating externally an oil body to a distilling temperature, continuing the conversion of said body by heating internally the oil body with an electrical resistance material immersed in the body of the oil and during the treatment maintaining a .pressure in excess of twenty pounds per ksquare inch during distillatio l ens-rnv EGLoFi.
