PROCESS OF CRACKING PETROLEUM OIL.
Application filed October 17, 1923, Serial No. 668,980. Renewed May 28, 1928.
This invention relates to improvements in process of cracking petroleum oil, and refers more j articularly to the method of treating the residuum produced under cracking operation.
The invention will appear from the following description, reference being had to the accompanying drawing, of which the single figure is a diagrammatic view partly inside elevation and partly in vertical section of the apparatus.
Referring to the drawings (1) designates the furnace, in which is mounted a heating coil 2) to which fresh stock is fed by means of feed pump and feed line The hot oil passes out of the (oil through transfer line (5) controlled by throttle valve (3) to top of expansion chamber The vapors pass out of expansion chamber through pipe controlled by throttle valve to the lower end ofdephlegmator (11). The refiuxcondensate is drawn off from the bottom of dephlegmator through pipe (12) leading back to feed line (4) and provided with throttle valve (13). The uncondensed vapors pass out of the dephlegmator through pipe (14) controlled by throttle valve (15) to condenser coil (16) and thence through pipe (17) and throttle valve (18) to receiver (19). This receiver (19) s provided with gas outlet valve (20) and liquid outletvalve- (21). As a feature of the invention the residuum 1s drawn off from the bottom of the expansion chamber through pipe (22) controlled by throttle valve 23) and is passed first through a cooling coil (24) the outlet of which is controlled by throttle valve (25) through which the residuum flows'to a treating tank (26).
The residuum is introduced into tank 26 through perforated pipe (27) which extends tank (26) is adapted to-be-charged half full, or more, with liquid sulphur dioxide, which may be forced in through pipe (28) controlled by throttle valve (29). By means of the ac tion of the liquid sulphur dioxide after agitation the residuum will stratify into two fractions; one floating on top of the liquid sulphur dioxide, and the other dissolved in the liquid sulphur dioxide. The former is drawn out by pipe (80) controlled by valve (31) and the latter by pipe 30) controlled by valve (31').
The liquid sulphur dioxide and residuum are violently agitated together by means of the blades or fins (32) used on shaft driven from motor (234:).
The arrangement is such as to effectively SllbJQCt all parts of the residuum to the action of the liquid sulphur dioxide.
After the residuum has been permitted to stratify the upper layer is drawn off and subected to a caustic soda solution to remove therefrom any sulphur dioxide contained therein The bottom layer of residuum dissolved in the sulphur dioxide is likewise drawn off and distilled to separate the residuum content from the liquid sulphur dioxide. The upper layer so produced may be suitable for obtaining lubricating stock, particularly by subjecting it to sulphuric acid, or other treatments and distilled in suitable fractions. The lower layer upon similar treatment may make good cylinder stock.
The liquid sulphur dioxide selectively sepahydrocarbon oil, under heat and pressure, Y
which consists in withdrawing the residuum from such reaction zone, in passing the same through a. cooling zone, in then delivering the cooled residuum to a tank filled to at least fifty per cent of its capacity with liquid sulphur dioxide, in violent-1y agitating the residuum and the liquid sulphur dioxide in said tank, in then ceasing the agitation and permitting the residuum constituents and sulphur dioxide to stratify in upper and lower layers, in sepa rately drawing off the constituents from said upper and lower layers, and in subjecting the separately withdrawn constituents to hidependent chemical treatments, to obtain lubrieating stock from the upper stratum and cylinder stock from the lower stratum.
2. A process for treating residuum which accumulates in'the reaction zone of an oil cracking apparatus during the conversion of hydrocarbon oil under heat and pressure which comprises withdrawing the residuum from such reaction zone, passing the same through a cooling zone, thence delivering the lower strata and subjecting the separately withdrawn constituents to lndependent chem irul treatments to obtain lubricating stool:
trom the upper stratuinnnd cylinder stock from the lower stratum.
