Abstract
The invention discloses the method for crude oil extraction, step is as follows：（1）Crude oil is heated, so as to increase the mobility of crude oil；（2）The crude oil of heating is conveyed into several supercentrifuges successively and repeatedly centrifuged, heavy pitch in crude oil is separated, crude oil at least carries out three centrifugations, and the rotating speed of supercentrifuge is not less than 8000r/min when centrifuging every time, so as to obtain the crude oil that bitumen content is less.Above-mentioned the method for crude oil extraction can isolate the pitch in crude oil, so as to obtain the less crude oil of bitumen content, i.e. miscella；Then each oil product is isolated miscella is inputted into destilling tower into distillation, so on the one hand can substantially reduces the load of destilling tower, on the other hand can reduce the cost of transportation of crude oil, another further aspect can reduce the environmental pollution produced during distillation.
Description
Technical field
The present invention relates to crude Treatment technique, and in particular to the method for crude oil extraction.
Background technology
In order to produce a variety of oil products, the crude oil of exploitation, which can be injected into a destilling tower, to be distilled, using each
The difference of boiling point between individual oil product, so that the different oil products such as the diesel oil in crude oil, lubricating oil, gasoline, aero oil be isolated
Come；But it is due to there is pitch in crude oil, destilling tower is produced larger load when distilling the crude oil, it is another
The pitch that aspect can increase in the cost of transportation of crude oil, another further aspect crude oil when transporting crude oil distillation can pollute when distilling
Environment.
The content of the invention
The technical problems to be solved by the invention are：To provide a kind of can isolate the method for crude oil extraction of pitch in crude oil.
In order to solve the above problems, the technical solution adopted in the present invention is：The method of crude oil extraction, is characterized in：Step is such as
Under：（1）Crude oil is heated, so as to increase the mobility of crude oil；（2）By the crude oil of heating be conveyed into successively several high speeds from
Repeatedly centrifuged in scheming so that heavy pitch can be separated in crude oil, crude oil at least carries out three centrifugations, and
And the rotating speed of supercentrifuge is not less than 8000r/min when centrifuging every time, so as to obtain the crude oil that bitumen content is less.
Further, foregoing the method for crude oil extraction, wherein：The Crude Oil Transportation of heating is entered into supercentrifuge and heating
Crude oil transported between each supercentrifuge using thermal insulation pump be incubated conveying, so as to keep the mobility of crude oil.
Further, foregoing the method for crude oil extraction, wherein：In step（1）It is middle by heating crude oil to 50~120 DEG C.
Further, foregoing the method for crude oil extraction, wherein：The rotating speed of supercentrifuge is 10000 when crude oil is centrifuged every time
~15000r/min.
Advantages of the present invention is：The method of crude oil extraction of the present invention can isolate the pitch in crude oil, so as to be dripped
The less crude oil of blue or green content, i.e. miscella；Then each oil product is isolated miscella is inputted into destilling tower into distillation, this
On the one hand sample can substantially reduce the load of destilling tower, on the other hand can reduce the cost of transportation of crude oil, another further aspect can reduce steaming
The environmental pollution produced when evaporating.
Brief description of the drawings
Fig. 1 is the schematic flow sheet of the method for crude oil extraction of the present invention.
Embodiment
With reference to specific embodiments and the drawings, the present invention is described in further detail.
As shown in figure 1, the method for crude oil extraction, step is as follows：（1）Crude oil in crude oil storage tank 1 is extracted by pump 2, then will
Crude oil is sent to middle heating tank 3 and is heated to 50~120 DEG C, so as to increase the mobility of crude oil, heating and temperature control 50~
120 DEG C be in order to prevent crude oil overheat and spontaneous combustion；（2）Crude oil that middle heating tank 3 heats is extracted and defeated by the first thermal insulation pump 4
Send into progress first time centrifugation in the first supercentrifuge 5 so that heavy pitch can be separated in crude oil, in reality
In, moisture while pitch is isolated in crude oil can also be separated, and then will pass through by the crude oil once centrifuged
Second thermal insulation pump 6, which is conveyed into the second supercentrifuge 7, carries out second of centrifugation, then passes through the crude oil Jing Guo secondary centrifuging
3rd thermal insulation pump 8 is conveyed into progress third time centrifugation in the 3rd supercentrifuge 9, so that the less crude oil of bitumen content is obtained,
That is miscella；The pitch in crude oil can more be separated by repeatedly centrifuging, thermal insulation pump is a kind of existing pump, insulation
Pump can carry out guarantor's mild heat in conveying to crude oil, so that the mobility of crude oil is kept by keeping the temperature of crude oil,
In the present embodiment, in order to improve production efficiency, the rotating speed of supercentrifuge is equal when centrifuging and only carried out three times, and centrifuging every time
For 10000~15000r/min, the rotating speed of centrifuge should not be too low also unsuitable too high, and rotating speed is too low to make pitch can not be from crude oil
In separate, rotating speed is too high to make centrifuge produce than larger vibrations, easily damage centrifuge.
