From a viewpoint of the efficient utilization of petroleum which is expected to be exhausted eventually, there have been the social needs to reuse the oil contained in the oil-containing material disposed of so far.
[0003] Generally, as the oil-containing material suitable on a commercial basis for reusing the oil contents, there may be enumerated crude oil sludge produced from crude oil, tanker sludge deposited on the ship bottom of a crude oil tanker, and tank sludge deposited on the bottom of an oil storage tank and so forth. This kind of sludge is featured to be much more easy 10 handle than the sludge containing metallic solid content produced by machining such as oil grinding and capable of being obtained concentratively in a quantitative manner.
[0004] To reuse the oil contained in the oil-containing material, it is necessary to separate the oil from the solid content in the oil-containing material without transform the oil content. A technology for performing separation of oil by vaporizing the oil content from the oil-containing material has been established. However, the oil separation technique has suffered a disadvantage such that the vaporized oil is flammable, and therefore, facilities and processing for preventing catching-fire are required, so it cannot easily be put into practice.
Thus, the technological developments of eliminating the risks of igniting the oil when vaporizing the oil content from the oil-containing material have been called for. 10005] The technique disclosed in Patent Literature 1 has been known as one example for eliminating the risks of igniting the oil when vaporizing the oil content from the oil-containing material.

[10028] The embodiment for fulfilling the oil separating method and oil separating apparatus according to the present invention will be described hereinafter with reference to the accompanying drawings.
[0029] FIG 1 through FIG 4 show the first embodiment for {fulfilling the oil separating method and oil separating apparatus according to the present invention.
[0030] Inthe first embodiment, there is illustrated the oil-containing material "A" from which the oil content "a" can appropriately be separated, e.g. crude oil sludge, tanker sludge and tank sludge as described above,
[0031] The first embodiment has a treatment vessel 1, a lid member 2, an oil-containing material supplying pipe 3, and a heated steam supplying pipe 4 as principal parts as shown in
FIGS. 1 and 2.
[0032] the treatment vessel 1 is shaped in an inverted frustum (mortar shape) and disposed on a not-shown support in a manner rotatable around the central axis "L". On the outer peripheral surface of the treatment vessel 1, there is disposed a gear 6 to which driving force is transmitted from the drive member 5 such as a motor via a chain. The driving force transmission from the drive member 5 via the gear 6 can be fulfilled by using relay gears in place of the chain or a belt pulley in place of the gear 6 and a belt in place of the chain.
[0033] The lid member 2 is formed in an inverted saucer shape and fixedly put on the treatment vessel 1 in a hermetically sealed state through a rotary support 7 offering sealing performance to the upper part of the treatment vessel 1. The lower part of the lid member 2 extends to the upper part of the outer peripheral surface of the treatment vessel 1 to define a gutler-shaped space with the outer peripheral surface of the treatment vessel 1. The space serves as a solid content gathering part 2a for gathering the solid content "b" separated from the oil-containing material "A". The solid content gathering part 2a is connected to a solid content discharge pipe 8 for discharging the solid content "b". On the upper part of the lid member 2, there is formed a dome 2b sloping toward the extension line of the central axis "1" of the treatment vessel 1 and bulging in a curved shape. To the dome 2b, an oil content discharge pipe 9 is connected for discharging the oil content "a" (including the powdery content) separated from the oil-containing material "A". 10034] To the solid content discharge pipe 8, a solid content/powdery content collecting unit 100 is connected as shown in FIG 3.
[0035] To the oil content discharge pipe 9, there is connected a oil content collecting unit 300 via cyclone separator 200 of a gravity type, collision type or the like for separating the oil content "a" and the powdery content as shown in FIG. 3. Further, the aforementioned solid content/powdery content collecting unit 100 is connected to the cyclone separator 200.
[0036] The oil-containing material supplying pipe 3 serves to supply the oil-containing material "A" to the inside of the treatment vessel 1 and is arranged to penetrate the bottom wall of the treatment vessel | from below having its axis line in agreement with the central axis "LL" of the treatment vessel 1 and protrude to a certain level of height within the treatment vessel 1. Thus, the feed end port 3a of the oil-containing material supplying pipe 3 is directed upward within the treatment vessel 1. Between the oil-containing material supplying pipe 3 and the bottom wall of the treatment vessel 1, a rotary support 10 having sealability is interposed.
[0037] To the oil-containing material supplying pipe 3, a sludge tank 500 for reserving the oil-containing material "A" is connected via a sludge pump 400 as shown in FIG 3. The sludge pump 400 serves to eject the oil-containing material "A" from the feed end port 3a of the oil-containing material supplying pipe 3 and may be provided with a stirring device and/or a heating device for making the oil-containing material into an ejectable muddy state according to need.
Further, the oil-containing material supplying pipe 3 may be covered with warming means over the outer periphery from the sludge pump 400 to the treatment vessel 1. The warming means 30 utilizes a heater or hot water capable of heating to the temperature at around 60°C to 90°C, so that the oil-containing material can be fed in their low-viscosity state.
[0038] The heated steam supplying pipe 4 serves to supply the heated steam "B" to the inside of the treatment vessel 1 and is arranged to penetrate the oil content discharge pipe 9 connected to the lid member 2 from the top of the treatment vessel 1 having its axis line in agreement with the central axis "L" of the treatment vessel 1 and protrude to a certain level of depth within the treatment vessel 1. Thus, the feed end port 4a of the heated steam supplying pipe 4 1s directed downward within the treatment vessel 1 in opposition to the feed end port 3a of the oil-containing material supplying pipe 3 with a small distance. The feed end port 4a of the heated steam supplying pipe 4 may be provided with a nozzle as necessary.
[0039] To the heated steam supplying pipe 4, a boiler 700 for producing the heated steam "B" is connected via a heat exchanger 600 for heating the heated steam "B" as shown in FIG, 3.
The overheated steam "B® is heated to 200°C to 500°C with the heat exchanger 600. 10040} According to the device of the first embodiment, the operation of separating the oil contents is fulfilled by supplying the oil-containing material "A" from the oil-containing material supplying pipe 3 and the heated steam "B" from the heated steam supplying pipe 4 while rotating the treatment vessel 1. FIG. 4 shows a flowchart of the operation of separating the oil content.
[0041] That is, the oil-containing material "A" made into muddy is ejected from the feed end port 3a of the oil-containing material supplying pipe 3 as the overheated steam "B" of high temperature and high pressure is ejected from the feed end port 4a of the overheated steam supplying pipe 4. The ejected oil-containing material "A" and the heated steam "B" come into collision with each other in opposite directions within the treatment vessel 1.
[0042] As a result, the oil-containing material "A" is instantaneously decomposed with the overheated steam "B" to vaporize and separate the oil content "a" (including the powdery content) from the solid content "b". During the decomposition of the oil-containing material "A" in this instant of time, the vaporized oil content "a" is effectively prevented from igniting as with the oil separating technique disclosed in Patent Literature 1 as noted above. In case where the interior of the treatment vessel 1 becomes high in temperature and pressure, an explosion-proof means such as a cooling means may be provided as may be necessary.
[0043] At this time, concentrative decomposition of the oil-containing material "A" is progressed in an area narrowly limited near a point of collision between the oil-containing material "A" and the heated steam "B". Namely, decomposition of the oil-containing material "A" is prevented from being progressed nonuniformly in a broad area within the treatment vessel 1 unlike the oil separating technique disclosed in Patent Literature 1 as noted above. Consequently, the separation of the oil content "a" can be carried out effectively.
[0044] Collision products (oil content "a" and solid content "b") produced by the collision of the oil-containing material "A" with the heated steam "B" are subjected to the centrifugal force created by rotating the treatment vessel 1.
[0045] The oil content "a" moves upward causing a vortex flow within the treatment vessel 1, consequently to be discharged from the oil content discharge pipe 9 with the guidance of the oil content discharge pipe 9 and the slope of the dome 2b of the lid member 2.
[0046] The solid content "b" subjected to the centrifugal force ascends in a spiral manner along the side wall inside the treatment vessel 1 and then is discharged from the solid content discharge pipe 8 with being gathered with the solid content gathering part 2a of the lid member 2. {00471 Thus, the separation of the oil content "a" and solid content "b" can be carried out assuredly and efiectively. 10048] FIG 5 shows the second embodiment for fulfilling the oil separating method and oil separating apparatus according to the present invention.
[0049] The second embodiment includes a spreading member 11 having a punching plate on the leading end side of the feed end port 4a of the steam supplying pipe 4.
[0050] According to the second embodiment, the heated steam "B" ejected from the feed end port 4a of the heated steam supplying pipe 4 can be spread with the spreading member 11.
Depending on the ejection quantity and ejection pressure of the heated steam "B",
concentrative decomposition of the oil-containing material which is progressed in an area narrowly limited near a point of collision between the oil-containing material "A" and the heated steam "B" is not hampered even by spreading the heated steam "B" in some measure.
[0051] FIG 6 shows the third embodiment for fulfilling the oil separating method and oil separating apparatus according to the present invention.
[0052] The third embodiment includes a guide plate 12 having a punching plate disposed along the side wall of the treatment vessel 1 with a distance to the side wall.
[0053] According to the third embodiment, even if the centrifugal brought about depending on the size of the solid content "b" is nonuniform, the entire solid content "b" can unfailingly ascend in a spiral manner along the side wall of the treatment vessel 1 by inhibiting stagnation and dropout of the solid content "b" with the guide plate 12.
PRACTICAL EXAMPLE
[0054] The desirable results regarding the first embodiment for fulfilling the oil separating method and oil separating apparatus according to the aforementioned present invention have been obtained on the basis of the following dimensional and numeric setting,
[0055] The treatment vessel 1 having a upper diameter of 1.5 meters, lower diameter of 0.3 meters, height of 1 meter to provide the performance of a disposal amount of I cubic meter was used. The treatment vessel 1 was driven to rotate at 500 rpm to 5000 rpm.
