Abstract
The present invention relates to a method for separating oil sludge and crude oil, which mainly comprises: oil sludge containing crude oil is directly put in a cracking furnace to be heated until the temperature reaches 400 to 700DEG; the pressure in the cracking furnace is kept at the pressure value of 3 kilograms, so the crude oil contained in the oil sludge is cracked into gas; the oil gas is cooled by a condenser, and the cooled oil gas forms mash gas and light crude oil; the mash gas is guided in a mash gas slot, and the light crude oil is guided in a crude oil slot, so users can use the mash gas and the light crude oil as intermediate raw materials in petrochemistry; in addition, plastic garbage and the oil sludge can be put in the cracking furnace together to be cracked at high temperature, so flammable garbage can be used as the energy source for indirectly heating the cracking furnace, and the plastic garbage can be cracked into light crude oil so as to increase the yield of the light crude oil.
Description
Technical field
The invention relates to the method for a kind of greasy dirt and crude separation, be meant that especially a kind of crude oil that will be contained in the greasy dirt flashes to oil gas earlier, is cooled to this oil gas the method for the greasy dirt and the crude separation of gas and light crude oil again.
Background technology
Crude oil normally contains deep layer at the bottom of ground, during the desire exploitation, after needing to explore the tram in oil field earlier, carry out the cutting of oil well again, after treating that the oil well cutting finishes, the crude oil of deep layer at the bottom of the ground can be extracted out, and the crude oil that will extract out inserts and transport in the unrefined oil tank all over the world, oneself is about to crude oil and refines into various operational light crude oils (as: white gasoline, diesel oil, premium motor fuel etc.) by various countries again; Yet, because of this crude oil is that deep layer is drawn out of at the bottom of the ground, contain a large amount of mud (as: soil, sand, heavy metal and other impurity) in the feasible crude oil that extracts, this mud itself has certain weight, make its bottom that can be deposited in unrefined oil tank, cause in the unrefined oil tank and can reduce, and this crude oil is to be built-up on the mud for the crude oil quantity of refining, cause the crude oil in the unrefined oil tank all to be refined use, do not meet economic benefit in fact.So, for the crude oil on the greasy dirt is extracted, in the streets promptly have and utilize centrifugal principle that the technology that crude oil and mud separate is come out, yet, it only can extract the crude oil of sub-fraction on the mud, most crude oil still is built-up on the mud, makes this greasy dirt suitable difficulty on subsequent disposal, no matter with its burning or abandon the pollution that all can cause air and environment.Therefore, current if can design a kind of technology that crude oil on the mud is extracted fully, the side is the task of top priority.
This shows that above-mentioned common technology still has many shortcomings, real non-one kindhearted design, and demand urgently being improved.
The present inventor is urgently to think to be improved innovation in view of the every shortcoming of above-mentioned common method institute's deutero-, and after concentrating on studies through taking great pains to attain one's goal for many years, and successfully the method for greasy dirt of the present invention and crude separation is finished in research and development finally.
Summary of the invention
Purpose of the present invention promptly is to provide a kind of high-temperature indirect type of heating that utilizes, the greasy dirt that crude oil and greasy dirt are separated and the method for crude separation.
An of the present invention purpose is to be to provide a kind of method that the crude oil of extraction can be refined into the greasy dirt and the crude separation of light crude oil and gas.
Another object of the present invention is to be to provide a kind of plastic rubber garbage that adds in greasy dirt, under the quantity that does not increase sludge residue, can increase light crude oil and refine the greasy dirt of quantity and the method for crude separation.
Another purpose of the present invention is to be to provide a kind of method of utilizing poor quality oil, combustible garbage, coal and gas as the greasy dirt and the crude separation of the fuel of indirect heating greasy dirt.
Can realize the method for the greasy dirt and the crude separation of foregoing invention purpose, its making step is:
1. the greasy dirt that will contain crude oil is earlier directly inserted and is heated to the 400-700 degree in the pyrolyzer, keeps 3 kilograms force value in this pyrolyzer, makes that contained crude oil is cracked into gaseous phase in the greasy dirt; Again oil gas is imported in the Reaktionsofen and heat, and control pressure, molecule is cut off the row irreversible reaction;
2. the oil gas of step 1 is delivered in the condenser and cooled off, making cooled oil gas form gas and density is 0.7～0.94 light crude oil;
3. the gas of step 2 is imported in the gas groove, compressed liquefaction stores, and makes it can barrelling or the usefulness of equipment heating is provided; And light crude oil imported in the unrefined oil tank, make the petroleum chemistry intermediate raw material for the user and use or be fractionated into gasoline, diesel oil or oil fuel; Stored gas and light crude oil can be used as the fuel of indirect heating pyrolyzer;
At last the sludge-drying in the pyrolyzer is removed, promptly finished separating of crude oil and mud.
In addition, can add plastic rubber garbage in addition in this step 1, make it under the situation that does not increase sludge residue, increase light crude oil output; And its applied fuel can be poor quality oil, self-produced gas, combustible garbage and the coal etc. that refine voluntarily.
The method of greasy dirt provided by the present invention and crude separation when comparing mutually with other common technology, has more following advantage:
1. the present invention utilizes high-temperature indirect heating in crude oil mud, makes this be built-up in oil evaporation olifiant gas on the mud, by condenser it is cooled to light crude oil and gas again, uses for the user.
2. the present invention can add plastic rubber garbage in greasy dirt, makes it under the quantity that does not increase sludge residue, and can increase the quantity that light crude oil refines.
3. bright fuel that utilizes poor quality oil, combustible garbage, coal and gas as the indirect heating greasy dirt of this name, and this poor quality oil and gas are to utilize method of the present invention to refine voluntarily.
