鉱物油、特に重油は硫黄や灰分不純物の含有量が多く、近年では環境負荷への対応からそのような不純物を効果的かつ低コストで除去することが望まれている。前記特許文献に記載の技術は超臨界水を用いるため、大がかりな設備が必要であり相当なコストがかかると考えられる。これに対して本発明は、鉱物油の不純物を効果的かつ低コストで除去できる方法及び装置を提供することを目的としている。 Mineral oils, especially heavy oils, have a high content of sulfur and ash impurities, and in recent years, it has been desired to remove such impurities effectively and at low cost in order to cope with the environmental load. Since the technique described in the patent document uses supercritical water, large-scale equipment is required and it is considered that a considerable cost is required. On the other hand, it is an object of the present invention to provide a method and an apparatus capable of removing impurities of mineral oil effectively and at low cost.

本発明は、水に活性酸素を生じさせ、その活性酸素が生じた水に鉱物油を混合し、その混合液を水と不純物と鉱物油とに分離させ、その分離されたあとの鉱物油を回収する鉱物油精製方法である。 In the present invention, active oxygen is generated in water, mineral oil is mixed with the water in which the active oxygen is generated, the mixed solution is separated into water, impurities and mineral oil, and the separated mineral oil is used.

本発明によれば、水に活性酸素を生じさせて鉱物油を精製するので、鉱物油の不純物を効果的かつ低コストで除去できる。 According to the present invention, since active oxygen is generated in water to purify mineral oil, impurities of mineral oil can be effectively and inexpensively removed.

図１は、本発明による鉱物油精製装置の一例の基本構成図である。
鉱物油精製装置１は、水に活性酸素を生じさせる水活性化装置１０と、その活性酸素が生じた水に鉱物油を混合する鉱物油混合装置１１と、その混合液を静止状態に保って水と不純物と鉱物油とに自然分離させる鉱物油分離装置１２とを備えている。 FIG. 1 is a basic configuration diagram of an example of a mineral oil refining apparatus according to the present invention.
The mineral oil refining device 1 keeps the water activating device 10 that generates active oxygen in water, the mineral oil mixing device 11 that mixes mineral oil with the water in which the active oxygen is generated, and the mixed solution in a stationary state. It is provided with a mineral oil separating device 12 that naturally separates water, impurities, and mineral oil.

鉱物油混合装置１１に供給される鉱物油は特に制限されず、重油、軽油、灯油等が可能である。特に重油は硫黄や灰分不純物の含有量が多いのであるが、本発明は、そのような不純物の除去に特段の効果を有する。 The mineral oil supplied to the mineral oil mixing device 11 is not particularly limited, and heavy oil, light oil, kerosene and the like can be used. In particular, heavy oil has a high content of sulfur and ash impurities, and the present invention has a special effect on removing such impurities.

鉱物油について簡単に説明すると、重油はＡ、Ｂ、Ｃの区分があり、Ａ重油（１号）は炭化水素分子の平均炭素数が約１６．３（標準偏差３．８）、硫黄分質量が０．５％以下、灰分質量が０．０５％以下である。Ｂ重油は炭化水素分子の平均炭素数が約１７．１（標準偏差３．０）、硫黄分質量が３％以下、灰分質量が０．０５％以下である。Ｃ重油（１号）は炭化水素分子の平均炭素数が約２０．２（標準偏差４．９）、硫黄分質量が３．５％以下、灰分質量が０．１％以下である。
本発明によれば、例えば前記Ａ重油の硫黄分重量を０．１％以下まで除去することが可能であり、特に有効である。
なお鉱物油精製装置で不純物を除去したあとの重油を、更に適切なフィルターでろ過することにより、微小な凝固物を除去することも可能である。このようなフィルター処理によって、より高品位な鉱物油が得られる。
また軽油は炭化水素分子の平均炭素数が約１７．０（標準偏差２．７）、硫黄分質量が１０ｐｐｍ以下である。灯油は炭化水分子の平均炭素数が約１２．９（標準偏差１．６）、硫黄分質量が８ｐｐｍ以下である。本発明は、このような軽油、灯油に対しても硫黄、灰分不純物を除去することが可能である。 To briefly explain mineral oil, heavy oil is classified into A, B, and C. Heavy oil A (No. 1) has an average carbon number of hydrocarbon molecules of about 16.3 (standard deviation 3.8) and sulfur content. Is 0.5% or less, and the ash content mass is 0.05% or less. Heavy oil B has an average carbon number of hydrocarbon molecules of about 17.1 (standard deviation 3.0), a sulfur content of 3% or less, and an ash content of 0.05% or less. Heavy oil C (No. 1) has an average carbon number of about 20.2 (standard deviation 4.9), a sulfur content of 3.5% or less, and an ash content of 0.1% or less.
According to the present invention, for example, it is possible to remove the sulfur content weight of the heavy fuel oil A to 0.1% or less, which is particularly effective.
It is also possible to remove fine coagulated substances by further filtering the heavy oil after removing impurities with a mineral oil refiner with an appropriate filter. By such filtering, higher quality mineral oil can be obtained.
Further, light oil has an average carbon number of hydrocarbon molecules of about 17.0 (standard deviation 2.7) and a sulfur content mass of 10 ppm or less. Kerosene has an average carbon number of carbonized water molecules of about 12.9 (standard deviation 1.6) and a sulfur content mass of 8 ppm or less. The present invention can remove sulfur and ash impurities from such light oil and kerosene.

水活性化装置１０は、例えば光触媒の作用によって水に活性酸素を生じさせる光触媒装置として構成してもよい。光触媒装置は、酸化チタンや酸化タングステン等の光触媒活性物質の微粒子を多孔質セラミックやゼオライト等の担体に固定した光触媒を、透明なパイプ中に封じ、この光触媒に対してＵＶランプ等から紫外線を照射するようにして構成できる。この場合、パイプに水を通じさせれば、光触媒の作用によって水に活性酸素が生じる。 The water activation device 10 may be configured as a photocatalyst device that generates active oxygen in water by the action of a photocatalyst, for example. In the photocatalyst device, a photocatalyst in which fine particles of a photocatalyst active substance such as titanium oxide or tungsten oxide are fixed on a carrier such as porous ceramic or zeolite is sealed in a transparent pipe, and the photocatalyst is irradiated with ultraviolet rays from a UV lamp or the like. It can be configured as follows. In this case, if water is passed through the pipe, active oxygen is generated in the water by the action of the photocatalyst.

光触媒装置に供給される水は、例えばＲＯ膜で処理された純水（超純水）であるが、光触媒装置に供給される前に、二酸化炭素及び酸素が溶解されている。この二酸化炭素、酸素は空気中から自然溶解したものでもよい。あるいは他の方法で高濃度に溶解、あるいは気泡として含有させたものでもよい。 The water supplied to the photocatalyst device is, for example, pure water (ultrapure water) treated with an RO membrane, but carbon dioxide and oxygen are dissolved before being supplied to the photocatalyst device. The carbon dioxide and oxygen may be naturally dissolved in the air. Alternatively, it may be dissolved in a high concentration by another method or contained as bubbles.

鉱物油混合装置１１は、例えば１：１の所定比率で水に鉱物油を混合する装置である。鉱物油混合装置１１は、水タンクから導いた管路、鉱物油タンクから導いた管路のそれぞれに計量ポンプ等を設けて、その下流側でこれらの管路を合流させるような構成としてもよい。また鉱物油混合装置１１は、水と鉱物油との混合液を貯めるタンクを更に設けて、そこで混合液を一定時間撹拌してもよい。 The mineral oil mixing device 11 is a device that mixes mineral oil with water at a predetermined ratio of, for example, 1: 1. The mineral oil mixing device 11 may be configured such that a measuring pump or the like is provided in each of the pipeline led from the water tank and the pipeline led from the mineral oil tank, and these pipelines are merged on the downstream side thereof. .. Further, the mineral oil mixing device 11 may further provide a tank for storing a mixed liquid of water and mineral oil, and the mixed liquid may be agitated there for a certain period of time.

鉱物油分離装置１２は、水と鉱物油との混合液を貯めるタンクであって、混合液が時間経過によって、水と不純物と鉱物油とに自然分離したあと、その鉱物油の部分を回収することが可能なように構成されている。あるいは遠心分離によって鉱物油と水とを分離してもよい。分離したあとの鉱物油の取出し方に特に制限はないが、タンクの底から比重の重い水と不純物とを排水して鉱物油を残してもよい。なお水と鉱物油は比重が異なるので、水、不純物、鉱物油を遠心分離させることも可能である。 The mineral oil separation device 12 is a tank for storing a mixed liquid of water and mineral oil, and after the mixed liquid naturally separates into water, impurities and mineral oil over time, the portion of the mineral oil is recovered. It is configured to be possible. Alternatively, the mineral oil and water may be separated by centrifugation. There is no particular limitation on how to take out the mineral oil after separation, but the mineral oil may be left by draining heavy water and impurities from the bottom of the tank. Since water and mineral oil have different specific gravities, it is possible to centrifuge water, impurities, and mineral oil.

次いで鉱物油精製装置１の基本動作を説明する。
光触媒装置に供給される水には二酸化炭素及び酸素が含まれているのであるが、この水の一部は、光触媒の作用によって分解されて、いわゆる活性酸素が生じる。活性酸素は例えばＯＨラジカル等であって非常に強い酸化作用を呈する。不純物は硫黄、炭素、ミネラルを含む不特定な化合物である。そしてそのような不純物は、活性酸素が存在する環境では何らかの化学反応を起こし鉱物油又は水から凝集、分離する。このときの化学反応を特定することは難しいのであるが、現象としては鉱物油分離装置１２のタンクにおいて鉱物油と水とが自然分離し、更に不純物の一部は鉱物油と水との境界に浮遊し、また他不純物の一部は底部に沈殿した状態になることが確認されている。なお鉱物油と水との境界に浮遊する不純物は有機不純物（すす等）であり、底部に沈殿する不純物は無機不純物である。
図２は、鉱物油分離装置において混合液が鉱物油、水、不純物に自然分離した状態を示す模式図である。このように鉱物油、水、不純物は層状に自然分離するのである。 Next, the basic operation of the mineral oil refining apparatus 1 will be described.
The water supplied to the photocatalyst device contains carbon dioxide and oxygen, and a part of this water is decomposed by the action of the photocatalyst to generate so-called active oxygen. Active oxygen is, for example, OH radical and exhibits a very strong oxidizing action. The impurities are unspecified compounds containing sulfur, carbon and minerals. Then, such impurities cause some chemical reaction in the environment where active oxygen is present, and aggregate and separate from mineral oil or water. It is difficult to specify the chemical reaction at this time, but as a phenomenon, the mineral oil and water are naturally separated in the tank of the mineral oil separation device 12, and some of the impurities are at the boundary between the mineral oil and water. It has been confirmed that it floats and some of the other minerals are precipitated at the bottom. Impurities floating at the boundary between mineral oil and water are organic impurities (soot, etc.), and impurities precipitated at the bottom are inorganic impurities.
FIG. 2 is a schematic view showing a state in which the mixed liquid is naturally separated into mineral oil, water, and impurities in the mineral oil separation device. In this way, mineral oil, water, and impurities are naturally separated into layers.

このように本発明によれば、水に活性酸素を生じさせて鉱物油を精製するのであるが、水に活性酸素をさせる手段として光触媒、あるいは後述のようにキャビテーションを用いれば活性酸素が非常に低コストで連続生成でき、その結果、鉱物油の不純物の除去も効果的かつ低コストに行えることになる。 As described above, according to the present invention, active oxygen is generated in water to purify mineral oil, but if a photocatalyst or cavitation as described later is used as a means for producing active oxygen in water, the active oxygen is very high. It can be continuously produced at low cost, and as a result, impurities in mineral oil can be removed effectively and at low cost.

また鉱物油精製装置１には、活性酸素の作用によって水に含まれていた二酸化炭素が還元されて一酸化炭素が生じ、その一酸化炭素と鉱物油の分子とが反応することによって新たな鉱物油が生じる、すなわち鉱物油が増量する作用もある。
鉱物油混合装置１１では、前記反応が生じつつある水と鉱物油とが混合されるのであるが、ここで合成された鉱物油は、更に水素及び一酸化炭素との反応によって鎖状構造を伸ばしていく。このとき周囲には多数の雛形鉱物油が存在している。そのため、鉱物油の鎖状構造の伸びは雛形鉱物油と同じ長さとなった段階で実質的に停止するように見える。これは雛形鉱物油が非常に多数であるため、その内の極一部の鎖錠構造が伸びたとしても、それが観察し難くなるためと考えられる。このような反応によって雛形鉱物油と略同一組成の鉱物油が合成されるのである。またこのとき混合液における鉱物油は自然増量し、水は自然減少する。この鉱物油の増量は理想的な条件では約１０％に達することが実験によって確認されている。 Further, in the mineral oil refining apparatus 1, carbon dioxide contained in water is reduced by the action of active oxygen to generate carbon monoxide, and the carbon monoxide reacts with the molecules of mineral oil to produce a new mineral. It also produces oil, that is, increases the amount of mineral oil.
In the mineral oil mixing device 11, the water in which the reaction is occurring and the mineral oil are mixed, and the mineral oil synthesized here further extends the chain structure by the reaction with hydrogen and carbon monoxide. To go. At this time, a large number of template mineral oils are present in the surrounding area. Therefore, the elongation of the chain structure of the mineral oil seems to stop substantially when it reaches the same length as the template mineral oil. It is considered that this is because there are so many template mineral oils that even if the locking structure of a very small part of them is stretched, it is difficult to observe it. By such a reaction, a mineral oil having substantially the same composition as the template mineral oil is synthesized. At this time, the amount of mineral oil in the mixed solution naturally increases, and the amount of water naturally decreases. Experiments have confirmed that this increase in mineral oil reaches about 10% under ideal conditions.

鉱物油分離装置１２では、鉱物油と水との混合液をタンクに貯めて静止状態に保持する。すると時間経過によって混合液が鉱物油と水とに自然分離する。こうして自然分離したあとの鉱物油を回収すれば、不純物の少ない高品位な鉱物油が得られる。 In the mineral oil separating device 12, a mixed liquid of mineral oil and water is stored in a tank and kept in a stationary state. Then, the mixed solution naturally separates into mineral oil and water over time. By recovering the mineral oil after natural separation in this way, a high-quality mineral oil with few impurities can be obtained.

更に前記反応における水、鉱物油の容積変化を、模式図を使って説明する。
図３（ａ）、（ｂ）、（ｃ）はそれぞれ、混合前の水、鉱物油の容積、水と鉱物油との混合液の容積、混合液が鉱物油と水とに分離したあとの水、鉱物油の容積を示す模式図である。
図３（ａ）に示すように同容積の水と鉱物油（鉱物油：水＝１０：１０）とを混合すると、図３（ｂ）に示すようにそれらの容積を合わせただけの混合液（容積２０）になる。鉱物油が合成されたあとの混合液は図３（ｃ）に示すように時間経過によって鉱物油と水とに二層分離する。このとき鉱物油は自然増量しており、水は自然減量している（例えば鉱物油：水＝１１：９）。 Further, the volume change of water and mineral oil in the reaction will be described with reference to a schematic diagram.
3 (a), (b), and (c) show the volume of water before mixing, the volume of mineral oil, the volume of the mixed solution of water and mineral oil, and the volume of the mixed solution after the mixed solution is separated into mineral oil and water, respectively. It is a schematic diagram which shows the volume of water and mineral oil.
When water of the same volume and mineral oil (mineral oil: water = 10:10) are mixed as shown in FIG. 3 (a), a mixed solution in which the volumes are simply combined as shown in FIG. 3 (b). (Volume 20). After the mineral oil is synthesized, the mixed solution is separated into two layers of mineral oil and water with the passage of time as shown in FIG. 3 (c). At this time, the amount of mineral oil is naturally increasing and the amount of water is naturally decreasing (for example, mineral oil: water = 11: 9).

図４は、本発明による鉱物油精製装置の他例の基本構成図である。
この鉱物油精製装置１は、水活性化装置１０の構成が前記の例とは異なっている。すなわちこの例の水活性化装置１０は、光触媒装置とキャビテーション装置とを直列接続した構成になっている。
キャビテーション装置は、水にキャビテーションを生じさせて活性化させる装置である。例えばキャビテーション発生装置は、水を加圧して流通させる管路の中間部内側に複数の突起を設ける、あるいはオリフィスを設けることで構成できる。そのような管路に水を圧送付すると、複数の突起あるいはオリフィスを設けた部分でその水が加速されて減圧沸騰し、蒸気バブルが生じる。このバブルが加圧によって消滅するときに局所的に高温高圧場が形成され、そこで水が熱分解されて活性酸素が生じる。
この例では、光触媒装置とキャビテーション発生装置とを組み合わせることで水活性化装置１０を構成している。しかし水活性化装置１０はキャビテーション装置のみで構成することも可能である。 FIG. 4 is a basic configuration diagram of another example of the mineral oil refining apparatus according to the present invention.
In this mineral oil refining device 1, the configuration of the water activating device 10 is different from the above example. That is, the water activation device 10 of this example has a configuration in which a photocatalyst device and a cavitation device are connected in series.
A cavitation device is a device that causes and activates cavitation in water. For example, the cavitation generator can be configured by providing a plurality of protrusions or orifices inside the middle portion of the conduit for pressurizing and circulating water. When water is pressure-fed into such a conduit, the water is accelerated and boiled under reduced pressure at a portion provided with a plurality of protrusions or orifices, and a steam bubble is generated. When this bubble disappears by pressurization, a high-temperature and high-pressure field is locally formed, where water is thermally decomposed to generate active oxygen.
In this example, the water activation device 10 is configured by combining the photocatalyst device and the cavitation generator. However, the water activation device 10 can also be composed of only a cavitation device.

図５は、本発明による鉱物油精製装置の更なる他例の基本構成図である。
この鉱物油精製装置１は、水活性化装置１０、鉱物油混合装置１１、鉱物油分離装置１２を適温に保つための温度管理設備１３を備えている点が特徴である。すなわち温度管理設備１３は、水及び、水と鉱物油との混合液の温度を所定の温度範囲に管理する。
温度管理設備１３は、水活性化装置１０、鉱物油混合装置１１、鉱物油分離装置１２を囲う恒温槽として構成してもよい。あるいは水活性化装置１０、鉱物油混合装置１１、鉱物油分離装置１２が設置された部屋空間のための空調設備であってもよい。
このような温度管理設備１３によって、水活性化装置１０、鉱物油混合装置１１、鉱物油分離装置１２の温度を、摂氏２０〜４５度、望ましくは３０〜４０度、更に望ましくは３７〜３８度に保つとよい。一般に温度が上がれば光触媒の活性は上昇するが、二酸化炭素や酸素などの溶解度が低下する。また温度が１５℃以下になると水のクラスターが大きくなるため、ＲＯ膜（逆浸透膜）の性能が低下する。よって、摂氏２０〜４５度でも反応は起こるものの、摂氏３７〜３８度が最適である。
温度による鉱物油の収量の変化について次のような実験結果が得られている。
温度が摂氏２０度のときの鉱物油の収量（自然増量分）は４％、摂氏２５度のときの鉱物油の収量は６％、摂氏３０度のときの鉱物油の収量は８％、摂氏３７〜３８度のときの鉱物油の収量は１０％、摂氏４０度のときの鉱物油の収量は６％であった。 FIG. 5 is a basic configuration diagram of another example of the mineral oil refining apparatus according to the present invention.
The mineral oil refining device 1 is characterized in that it is provided with a temperature control device 13 for keeping the water activating device 10, the mineral oil mixing device 11, and the mineral oil separating device 12 at an appropriate temperature. That is, the temperature control equipment 13 controls the temperature of water and the mixed liquid of water and mineral oil within a predetermined temperature range.
The temperature control equipment 13 may be configured as a constant temperature bath that surrounds the water activation device 10, the mineral oil mixing device 11, and the mineral oil separation device 12. Alternatively, it may be an air conditioning facility for a room space in which a water activation device 10, a mineral oil mixing device 11, and a mineral oil separating device 12 are installed.
With such a temperature control equipment 13, the temperature of the water activating device 10, the mineral oil mixing device 11, and the mineral oil separating device 12 is set to 20 to 45 degrees Celsius, preferably 30 to 40 degrees Celsius, and more preferably 37 to 38 degrees Celsius. It is good to keep it in. Generally, as the temperature rises, the activity of the photocatalyst increases, but the solubility of carbon dioxide, oxygen, etc. decreases. Further, when the temperature becomes 15 ° C. or lower, water clusters become large, so that the performance of the RO membrane (reverse osmosis membrane) deteriorates. Therefore, although the reaction occurs even at 20 to 45 degrees Celsius, 37 to 38 degrees Celsius is optimal.
The following experimental results have been obtained regarding changes in the yield of mineral oil with temperature.
When the temperature is 20 degrees Celsius, the yield of mineral oil (natural increase) is 4%, when the temperature is 25 degrees Celsius, the yield of mineral oil is 6%, when the temperature is 30 degrees Celsius, the yield of mineral oil is 8%, and the yield is 8%. The yield of mineral oil at 37-38 degrees was 10%, and the yield of mineral oil at 40 degrees Celsius was 6%.

またこの例の鉱物油精製装置１は、水に酸素ガスを供給する酸素供給装置１４を更に備えている。酸素供給装置１４は、水活性化装置１０に供給される前の水に、酸素ガスを溶解させる。すなわちこの例では、二酸化炭素を含んだ水に酸素を更に含ませてから活性酸素を生じさせるようにしている。このようにすると活性酸素が効率的に生成されるので、結果として鉱物油の収量が増すという効果が得られる。 Further, the mineral oil refining device 1 of this example further includes an oxygen supply device 14 for supplying oxygen gas to water. The oxygen supply device 14 dissolves oxygen gas in water before it is supplied to the water activation device 10. That is, in this example, active oxygen is generated after further adding oxygen to water containing carbon dioxide. In this way, active oxygen is efficiently generated, and as a result, the effect of increasing the yield of mineral oil can be obtained.
