FIELD OF THE INVENTION

&null;0001&null; This invention relates to a method of separating the oil slurry with the crude oil, especially refers to a method of separating the light crude oil and the crude oil which to evaporate the crude oil inside the oil slurry first into the oil gas, and to cool such oil gas into the gas and the light crude oil.

DESCRIPTION OF THE PRIOR ART

&null;0002&null; Usually the crude oil is buried in the deep layer of the earth, when people want to mint the oil, they should first mint the correct location of the oil land, next to proceed the dipping of the oil well, after the oil well is being minted, the crude oil could then be dipped from the deep layer of the earth and the crude oil being extracted could then be delivered from everywhere in the world. Next it will be refined to become the light crude oil for usage by each countries such as leadless oil, diesel oil, high-order gas oil, etc; however, since such crude oil is extracted from the deep layer of the earth, there contains large amounts of slurry in such extracted crude oil such as the dirt, the sand, the heavy metal as well as other impurities, there contains a certain amounts of weight for said slurry such that it will precipitate in the bottom location of the original oil tank such that the quantities of crude oil for cracking inside said oil tank is reduced; besides, since the crude oil is attached on the slurry such that the crude oil in the crude oil tank could not be used by cracking which is not an economical situation. So, in order to extract the crude oil from the crude oil tank, there is a technology for separating the crude oil with the oil slurry according to the principle of centrifugal force; however, there is only a small fraction of the crude oil that could be extracted by said technology wherein most of the crude oil is attached on the crude oil which makes the subsequent processing of the crude oil difficult, it will cause a lot of air or environmental pollution whatever to burn it or to discard it. Thus, if it could design a technology of extracting the crude oil on the oil slurry, it is the most emergency thing nowadays.

&null;0003&null; Thus it is clear that the above-mentioned conventional technology is not a good method which requires to be bettered. The inventor of this invention, after several years' hard-studying, finally invented this invention.

SUMMARY OF THE INVENTION

&null;0004&null; The object of this invention is to provide a method of separating the oil slurry with the crude oil by utilizing high temperature indirect heating method.

&null;0005&null; Another object of this invention is to provide a method of separating the oil slurry with the crude oil by cracking the extracted crude oil into the light crude oil and the gas.

&null;0006&null; Another object of this invention is to provide a method of separating the oil slurry with the crude oil of which it could add the plastic junk into the oil slurry which could increase the quantities of the light crude oil being cracked without increasing the quantities of slurry dirt.

&null;0007&null; Still another object of this invention is to provide a method of separating the oil slurry with the crude oil which utilizes the bad quality oil, combustible junk as the fuel of direct heating the oil slurry by indirect heating method.

&null;0008&null; The fabricating steps of the method of separating the oil slurry with the crude oil achieving the above-mentioned object of invention are as follows:

&null;0009&null; 1. first to put the oil slurry containing the crude oil into the cracking furnace to heat to 400-700 degree wherein there remains the pressure value of 3 kg inside said cracking furnace such that the crude oil contained by said oil slurry is cracked into gas status;

&null;0010&null; 2. to cool the oil gas in step 1 and cool it such that the oil gas after being cooled forms the gas and the light crude oil;

&null;0011&null; 3. to guide the gas in step 2 into the gas tank and to guide the light crude oil tank into the crude oil tank for the usage as the chemical intermediate or to be distillated into the gas oil, diesel oil or the fuel oil.

&null;0012&null; Besides, there adds the plastic junk in the step 1 such that it could increase the yield of the light crude oil under the condition of non-increasing the slurry junk; and the fuel being used could be the self-extract bad-quality oil, self-produced gas, combustible junk as well as the coal, etc.

BRIEF DESCRIPTION OF THE DRAWINGS

&null;0013&null; The drawings disclose an illustrative embodiment of the present invention which serves to exemplify the various advantages and objects hereof, and are as follows:

&null;0014&null; FIG. 1 is the step fig of the method of separating the oil slurry with the crude oil of this invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

&null;0015&null; Please refer to FIG. 1, which is the step of the method of separating the oil slurry with the crude oil of this invention; the fabricating step is as follows:

&null;0016&null; Step1: to proceed heating by putting the oil slurry in the cracking furnace of a combustion chamber, said heating fuel could be: bad quality oil, gas, coal as well as combustible junk, such that the crude oil in the oil slurry is heated to evaporate to be the oil gas, and it separates with the slurry completely so the slurry dirt completing separation is very dry as a mine sand;

&null;0017&null; Step2: guide the oil gas into the reaction furnace and proceed pressure control to proceed irreversible reaction by cleaving the molecules.

&null;0018&null; Step3: cool the oil gas in step 2 to the condenser to near the ambient temperature such that the liquid being condensed and after precipitation become the light crude oil wherein the density of said light oil is 0.7-0.94 and partial uncondensed gas is oil gas;

&null;0019&null; Step4: to guide the light crude oil in step 3 to storage in the crude oil tank to refine the related diesel oil, gas oil, etc.

&null;0020&null; Step5: to store the oil gas in step 3 after compression and liquification such that it could be packed into the bottle or be used for proving the equipment of heating;

&null;0021&null; Step6: next to clear the dry slurry inside the cracking furnace which completes the separation of the crude oil and the slurry.

&null;0022&null; Besides, it could also add a incombustible junk such as plastic typed junk into the cracking furnace to be heating and cracking with the oil slurry such that said incombustible junk could be cracked and evaporated into the oil gas so that the yield of the light crude oil and the gas increases wherein the quality of the slurry dirt inside the cracking furnace is a constant; besides, both the light crude oil and the gas refined by said step 4 and step 5 could be used as the fuel of indirect heating the cracking furnace.

&null;0023&null; The method of separating the oil slurry with the crude oil of this invention having the following advantages in comparison with the other conventional technologies:

&null;0024&null; 1. This invention heating the crude oil slurry indirectly by utilizing the high temperature such that the crude oil adhered to the slurry is evaporated into the oil gas, next to condense the crude oil slurry to be the light crude oil and the gas for providing the usage of the users through the condenser.

&null;0025&null; 2. This invention adds the plastic junk in the oil slurry so that it increases the quality of the light crude oil being refined without increasing the quality of the slurry dirt.

&null;0026&null; 3. This invention could utilize the bad quality oil, the combustible junk, the coal, as well as the gas as the fuel of indirect heating the hot oil slurry; besides, said bad quality oil could be refined by using the method of this invention.

&null;0027&null; Many changes and modifications in the above described embodiment of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
