Abstract
Description
本発明は、ポリクロロビフェニル類（以下ＰＣＢと称する）に代表される有害なハロゲン化芳香族化合物を安全に運搬あるいは移送する方法に関する。特に、ハロゲン化芳香族化合物の運搬時、たとえばトラック輸送時に、事故などの災害に遭遇した際にも、流出・漏洩等の二次災害を防止することができる、新規のハロゲン化芳香族化合物の運搬方法に関する。 The present invention relates to a method for safely transporting or transferring harmful halogenated aromatic compounds represented by polychlorobiphenyls (hereinafter referred to as PCB). In particular, new halogenated aromatic compounds that can prevent secondary disasters such as spills and leaks when transporting halogenated aromatic compounds, such as when transporting trucks, are encountered during disasters such as accidents. It relates to the transportation method.
有害物質であるハロゲン化芳香族化合物を安全に化学分解し、無害化処理することは、環境保全の観点から最重要課題となっている。特にコンデンサ、感圧複写紙、柱上トランス等に、かつてポリクロロビフェニル類（以下「ＰＣＢ」という）が使用されていたため、これらに使用されていたＰＣＢを処理施設などにおいて安全に無害化することが急務である。従来から、ハロゲン化芳香族化合物の分解方法に関しては、種々の提案がなされている。 Safely chemically decomposing and detoxifying halogenated aromatic compounds, which are harmful substances, is the most important issue from the viewpoint of environmental protection. In particular, since polychlorinated biphenyls (hereinafter referred to as “PCB”) were once used for capacitors, pressure-sensitive copying paper, pole transformers, etc., PCBs used for these must be made safe and harmless in processing facilities. Is an urgent need. Conventionally, various proposals have been made regarding methods for decomposing halogenated aromatic compounds.
ＰＣＢを含むハロゲン化芳香族化合物を処理するにあたり、これら化合物を処理施設に運搬する場合がある。通常に運搬される場合は勿論のこと、陸路・海路輸送において想定される事故等の災害時にも、かかるハロゲン化芳香族化合物が環境中に漏洩、流出するようなことがあってはならない。陸上・海上輸送において、ハロゲン化芳香族化合物の環境中への漏洩、流出を確実に防ぐことが最重要課題となっている。 In processing halogenated aromatic compounds including PCB, these compounds may be transported to a processing facility. Of course, such halogenated aromatic compounds must not leak into the environment or flow out in the event of a disaster such as an accident assumed in land and sea transportation, as well as normal transportation. In land and sea transportation, the most important issue is to reliably prevent leakage and outflow of halogenated aromatic compounds into the environment.
従来から、ハロゲン化芳香族化合物の運搬に関しては、運搬容器についてのみ種々のガイドラインが発行されている。例えば、非特許文献１（「ＰＣＢ廃棄物収集・運搬ガイドライン」［環境省大臣官房廃棄物・リサイクル対策部 平成１６年３月］）などが公開されている。本ガイドラインは、ＰＣＢ廃棄物の適正な収集・運搬を確保し、生活環境の保全及び公衆衛生の向上を図るため、廃棄物処理法に基づき、ＰＣＢ廃棄物の特性に鑑み、必要となる事項を具体的に示したものであり、ＰＣＢの環境中への漏洩、流出の防止を第一に考慮し、ハード面（運搬容器、施設等）に加え、ソフト面（教育、管理、緊急時対応マニュアル等）についても具体的な事項を盛り込んだものであることが記載されている。 Conventionally, regarding the transportation of halogenated aromatic compounds, various guidelines have been issued only for transportation containers. For example, Non-Patent Document 1 (“PCB Waste Collection and Transport Guidelines” [Ministry of the Environment Minister's Secretariat Waste and Recycling Countermeasures Department, March 2004]) and the like are published. These guidelines are based on the Waste Disposal Law and are based on the characteristics of PCB waste in order to ensure proper collection and transportation of PCB waste, and to preserve the living environment and improve public health. This is a concrete example, considering the prevention of PCB leakage into and out of the environment, and in addition to hardware (transport containers, facilities, etc.), software (education, management, emergency response manual) Etc.), it is described that it contains specific matters.
しかし、本ガイドラインには以下のような問題点を指摘することができる。ガイドライン記載の運搬方法はいずれも、ハロゲン化芳香族化合物を含む液状物を、ある基準を満たしたドラム缶やタンクローリー等で運搬する方法であり、ここに記載されている方法自体は充分安全に配慮したものである。しかし液状物運搬を前提とした場合、如何に万全を期したとしても、事故などの災害時の漏洩や流出まで防ぐことは非常に困難である。また液状物の場合、万一環境中に漏洩・流出した場合に回収が困難となる。さらに液状物を海上輸送する場合は、災害時の漏洩・流出のおそれがさらに増大し、また万一環境中に流出した場合に、これらを回収することはほぼ不可能となる。 However, this guideline can point out the following problems. Each of the transportation methods described in the guidelines is a method of transporting a liquid material containing a halogenated aromatic compound in a drum can or tank lorry that satisfies certain standards, and the method itself described here is sufficiently safe. Is. However, it is very difficult to prevent leaks and spills at the time of disasters such as accidents, no matter how perfect, if liquid material transportation is assumed. In the case of a liquid material, it is difficult to collect it if it leaks or flows out into the environment. Furthermore, when liquids are transported by sea, there is a further increase in the risk of leakage and spilling during a disaster, and in the unlikely event that they spill into the environment, it is almost impossible to recover them.

本発明は、ハロゲン化芳香族化合物を含む液状媒体を輸送、運搬する場合に、流出、漏洩のおそれがなく、たとえ海上、海中に放出されても直ちに回収可能な形態でかかる化合物を運搬する方法を提供する。 The present invention relates to a method for transporting a liquid medium containing a halogenated aromatic compound in such a form that there is no risk of spillage or leakage and can be recovered immediately even if released into the sea at sea. I will provide a.
本発明によるハロゲン化芳香族化合物の運搬方法は、ハロゲン化芳香族化合物を含有する媒体を固化し、該固化した該媒体を運搬することを特徴とする。以下、本発明を詳細に説明する。 The method for transporting a halogenated aromatic compound according to the present invention is characterized in that a medium containing a halogenated aromatic compound is solidified and the solidified medium is transported. Hereinafter, the present invention will be described in detail.
ハロゲン化芳香族化合物は、人体、動植物に対して強い毒性を示す化合物であり、特に催奇形性などのおそれから、有害物質として廃棄物の処理及び清掃に関する法律により指定されているものが多数ある。これら化合物が土壌、地下水、焼却灰、洗浄水、機械油等に存在する場合は、何らかの処理を施してこれらの濃度を基準値以下に減少させなければならないことが厳密に定められている。本発明において「ハロゲン化芳香族化合物」とは、芳香族化合物にフッ素、塩素、臭素及びヨウ素が１以上置換した化合物全般を指す。本発明では、例えばポリクロロビフェニル類（ＰＣＢ）、ダイオキシン類、フロン類、およびポリクロロベンゼン類等を指す。ＰＣＢとは、ビフェニル骨格に塩素原子が数個置換した化合物の総称であり、塩素原子の置換位置、置換数により多数の異性体が存在する。またダイオキシン類とは、狭義の意味ではダイオキシン類対策特別措置法で指定される特定の化合物を指すが、本発明では、いわゆる内分泌撹乱物質（環境ホルモン）として疑われるハロゲン化化合物を全て含む。 Halogenated aromatic compounds are compounds that are highly toxic to humans, animals and plants. Many of them are specified by laws on waste treatment and cleaning as harmful substances, especially because of teratogenicity. . When these compounds are present in soil, groundwater, incineration ash, washing water, machine oil, etc., it is strictly determined that some treatment must be applied to reduce their concentration below the reference value. In the present invention, the “halogenated aromatic compound” refers to all compounds in which one or more of fluorine, chlorine, bromine and iodine are substituted on the aromatic compound. In the present invention, for example, polychlorobiphenyls (PCB), dioxins, chlorofluorocarbons, polychlorobenzenes and the like are indicated. PCB is a general term for compounds in which several chlorine atoms are substituted on the biphenyl skeleton, and there are many isomers depending on the substitution position and the number of substitutions of chlorine atoms. Dioxins refer to specific compounds specified by the Special Measures for Countermeasures against Dioxins in a narrow sense, but in the present invention, all halogenated compounds suspected as so-called endocrine disrupting substances (environmental hormones) are included.
本発明において「ハロゲン化芳香族化合物を含有する媒体」とは、上記ハロゲン化芳香族化合物を含む物質であれば、気体、液体、固体を問わないが、一般には液状物質である。例えば、一般に高圧トランス、高圧コンデンサ、安定器などに使用される絶縁油；集中暖房、パネルヒータ、及び各種工業において使用される加熱冷却用熱媒体；油圧オイル、真空ポンプ油、切削油、極圧添加剤などを含む潤滑油；電線被覆用絶縁テープ用可塑剤、樹脂混合用可塑剤、接着剤、ニス・ワックス、アスファルト等混合用可塑剤；ノンカーボン紙や感圧複写紙用塗料、難燃性、耐食性、耐薬品性、耐水性等の性質を有する各種塗料及び印刷用インキなどに代表される熱安定性の高い油のことを指す。かかる媒体の一部では、かつてハロゲン化芳香族化合物が使用されていた。また、例えば重電機器用トランスに用いられる絶縁油や、絶縁油を用いる地中送電線などは、ポリ塩化ビフェニル類（ＰＣＢ）を絶縁油として用いていなくても微量のＰＣＢが混入している場合があり、かかる媒体中の微量混入ＰＣＢが大きな問題となっている。このような媒体中にハロゲン化芳香族化合物（ＰＣＢ）が溶解している場合、それが如何に低濃度であっても廃棄することはできず、保管し、一定の期間内に処分しなければならない。かかる物質を処分する場合に、処理工場への輸送が必要となり、本発明の方法などを用いて安全に輸送しなければならない。 In the present invention, the “medium containing a halogenated aromatic compound” may be a gas, liquid, or solid as long as it is a substance containing the halogenated aromatic compound, but is generally a liquid substance. For example, insulating oil generally used in high-voltage transformers, high-voltage capacitors, ballasts, etc .; central heating, panel heaters, and heating / cooling heat medium used in various industries; hydraulic oil, vacuum pump oil, cutting oil, extreme pressure Lubricating oil including additives; plasticizer for insulation tape for wire coating, plasticizer for resin mixing, adhesive, varnish / wax, asphalt, etc .; paint for non-carbon paper and pressure-sensitive copying paper, flame retardant It refers to oil with high thermal stability represented by various paints and printing inks having properties such as water resistance, corrosion resistance, chemical resistance and water resistance. In some of these media, halogenated aromatic compounds have been used in the past. In addition, for example, insulating oil used for transformers for heavy electrical equipment, underground transmission lines using insulating oil, etc., even if a small amount of PCB is mixed even if polychlorinated biphenyls (PCB) are not used as insulating oil There is a big problem of PCBs mixed in a small amount in such a medium. If a halogenated aromatic compound (PCB) is dissolved in such a medium, it cannot be discarded no matter how low it is, and must be stored and disposed of within a certain period of time. Don't be. When disposing of such a material, it is necessary to transport it to a processing factory, and it must be transported safely using the method of the present invention.
本明細書において上記媒体を「固化する」とは、化学的反応により流動性のほぼない物質に変化させることのほか、吸着材などに吸着させて、液状物質の流動性を失わせることをも含む概念である。ハロゲン化芳香族化合物を含有する液状媒体を固化する方法として、特に油吸着材または固化剤を用いる方法がある。 In this specification, “solidifying” the medium means not only changing the substance to a substantially non-fluidic substance by a chemical reaction, but also causing the liquid substance to lose its fluidity by being adsorbed on an adsorbent or the like. It is a concept that includes. As a method for solidifying a liquid medium containing a halogenated aromatic compound, there is a method using an oil adsorbent or a solidifying agent.
油吸着材とは、ハロゲン化芳香族化合物を含有する液体媒体を吸蔵して固体化する物質を云う。一方固化剤とは、化学的反応により固体状に変化させる薬剤を云う。本明細書において「固体」とは、液体のように流動性を有する物質に対する語として使用し、流動性がない、あるいは極めて少ない、固まった状態のもの全てを指す。すなわち、固体状に変化するとは、物理的な意味での固体になることの他、ゲルになること、ならびに粘着性に変化して流動性を失うこと、及び吸着材に吸蔵されることにより流動性を失うことなどを広く指すものとする。 The oil adsorbent refers to a substance that occludes a liquid medium containing a halogenated aromatic compound and solidifies. On the other hand, the solidifying agent refers to a drug that changes into a solid state by a chemical reaction. In this specification, the term “solid” is used as a term for a substance having fluidity such as a liquid, and refers to all solidified substances having no or very little fluidity. In other words, changing to a solid state means that, in addition to becoming a solid in the physical sense, it becomes a gel, and changes to stickiness to lose fluidity and is absorbed by the adsorbent. It shall refer broadly to loss of sex.
本発明の方法に使用する、ハロゲン化芳香族化合物を含有する液体媒体を固化することができる油吸着材として、従来から好適に使用されているものを用いることができる。
油吸着材として、例えば、クレー、シリカ、パーライト、石灰などの無機系油吸着材；ピートモス、綿、カポック、パルプなどの天然物系油吸着材；ポリプロピレン繊維、ポリスチレン繊維、ポリウレタン発泡体、疎水性繊維、又はこれらから構成される不織布、マット等、一般にオイルブロッター、オイルフェンスなどと呼ばれる、合成系油吸着材が挙げられる。
As the oil adsorbent that can be used to solidify the liquid medium containing the halogenated aromatic compound used in the method of the present invention, those conventionally used suitably can be used.
Examples of oil adsorbents include inorganic oil adsorbents such as clay, silica, perlite and lime; natural oil adsorbents such as peat moss, cotton, kapok and pulp; polypropylene fibers, polystyrene fibers, polyurethane foams, hydrophobic Synthetic oil adsorbents generally referred to as oil blotters, oil fences, etc., such as fibers or non-woven fabrics and mats composed of these, can be mentioned.
固化剤として、従来から好適に使用されているものを用いることができる。例えば、化学的反応により３次元網目構造を形成して、網目内部に液体媒体を取り込むことができる、ゲル化剤が挙げられる。かかるゲル化剤として、例えば金属石けん類、１２−ヒドロキシステアリン酸、ベンジリデンソルビトール、ソルビトールジアセタール、コレステロール系アミド化合物、糖誘導体類、及びアミノ酸類等が挙げられる。かかるゲル化剤は、液体媒体をゲル化させるために加熱を要件とする加熱型固化剤（加熱型ゲル化剤）である。 As the solidifying agent, those conventionally used suitably can be used. For example, a gelling agent capable of forming a three-dimensional network structure by a chemical reaction and incorporating a liquid medium inside the network can be mentioned. Examples of such gelling agents include metal soaps, 12-hydroxystearic acid, benzylidene sorbitol, sorbitol diacetal, cholesterol-based amide compounds, sugar derivatives, and amino acids. Such a gelling agent is a heating type solidifying agent (heating type gelling agent) that requires heating in order to gel the liquid medium.
さらにゲル化剤として、固化するために加熱を必要としない、樹脂酸類とアルカリ度類金属化合物の組合せ固化剤、樹脂酸類のアルカリ度類金属塩、またはロジンアミド誘導体などの有機ゲル化剤などが挙げられる。本明細書では、このようなゲル化剤を常温固化剤、あるいは常温ゲル化剤と称する。上記樹脂酸類として、例えばアビエチン酸、レボピマル酸、ネオアビエチン酸、パラストリン酸、ピマル酸、イソピマル酸、サンダラコピマル酸、デヒドロアビエチン酸、ジヒドロアビエチン酸、テトラヒドロアビエチン酸等が挙げられ、これらを単数又は複数混合して用いることができる。さらに樹脂酸類として、ガムロジン、ウッドロジン、トール油ロジン、不均化ロジン、水素化ロジン、脱水素化ロジン等、上記樹脂酸混合物が挙げられる。樹脂酸類と共に用いることができるアルカリ度類金属化合物は、樹脂酸類と反応して塩を形成することができる化合物であり、例えば、水酸化マグネシウム、酸化マグネシウム、水酸化カルシウム、酸化カルシウム、水酸化ストロンチウム、酸化ストロンチウム、水酸化バリウム、酸化バリウム、及びこれらの任意の混合物などが挙げられる。樹脂酸類のアルカリ土類金属塩は、上記樹脂酸のカルシウム塩、ストロンチウム塩、バリウム塩及びマグネシウム塩が挙げられる。特に樹脂酸類のカルシウム塩が好適に用いられる。 Furthermore, as gelling agents, organic gelling agents such as a combination solidification agent of resin acids and alkalinity metal compounds, alkalinity metal salts of resin acids, or rosinamide derivatives, which do not require heating to solidify, can be mentioned. It is done. In the present specification, such a gelling agent is referred to as a normal temperature solidifying agent or a normal temperature gelling agent. Examples of the resin acids include abietic acid, levopimaric acid, neoabietic acid, parastrinic acid, pimaric acid, isopimaric acid, sandaracopimalic acid, dehydroabietic acid, dihydroabietic acid, tetrahydroabietic acid, and the like. A plurality of them can be mixed and used. Furthermore, examples of the resin acids include the above resin acid mixtures such as gum rosin, wood rosin, tall oil rosin, disproportionated rosin, hydrogenated rosin, and dehydrogenated rosin. Alkalinity metal compounds that can be used with resin acids are compounds that can react with resin acids to form salts, such as magnesium hydroxide, magnesium oxide, calcium hydroxide, calcium oxide, strontium hydroxide. Strontium oxide, barium hydroxide, barium oxide, and any mixture thereof. Examples of the alkaline earth metal salts of resin acids include calcium salts, strontium salts, barium salts and magnesium salts of the resin acids. In particular, calcium salts of resin acids are preferably used.
また、油吸着材の機能と、固化剤の機能を併せ持つ、複合型材料として、ポリノルボルネン樹脂、スチレン−ブタジエン共重合体等が挙げられる。
油吸着材または固化剤を使用して、ハロゲン化芳香族化合物を含有する媒体を固化することができる。油吸着材を用いる場合は、吸蔵すべき媒体の量を勘案して油吸着材を用意し、これに該媒体を吸蔵させる。油吸着材は、吸蔵した油が圧力により再漏洩するおそれがあるため、吸蔵させる媒体に対応する量よりも多めに用意することが好ましい。
固化剤を用いる場合は、吸蔵すべき媒体がほぼ完全に固化するよう、該固化剤の量を算出する。使用する固化する媒体と固化剤の種類により、必要とされる固化剤の量は変化する。加熱型固化剤を使用する場合は、媒体に必要量の該固化剤を投入し、加熱し、好ましくはこの間媒体を混合した後、冷却することにより固化反応を進行させることができる。常温固化剤を使用する場合は、媒体に必要量の固化剤を投入して撹拌し、粘度が出てきたところで撹拌を停止して放置し、固化を進行させる。
Moreover, polynorbornene resin, a styrene-butadiene copolymer, etc. are mentioned as a composite type material which has the function of an oil adsorbent and the function of a solidifying agent.
Oil adsorbents or solidifying agents can be used to solidify media containing halogenated aromatic compounds. When an oil adsorbent is used, an oil adsorbent is prepared in consideration of the amount of medium to be occluded, and the medium is occluded therein. The oil adsorbing material is preferably prepared in a larger amount than the amount corresponding to the medium to be occluded, because the occluded oil may leak again due to pressure.
When a solidifying agent is used, the amount of the solidifying agent is calculated so that the medium to be occluded is almost completely solidified. The amount of solidifying agent required varies depending on the solidification medium used and the type of solidifying agent. When a heating type solidifying agent is used, the solidification reaction can be advanced by adding the necessary amount of the solidifying agent to the medium and heating, preferably mixing the medium during this time and then cooling. When using a normal temperature solidifying agent, a necessary amount of the solidifying agent is added to the medium and stirred, and when the viscosity comes out, the stirring is stopped and the solidification proceeds.
本発明の方法により、ハロゲン化芳香族化合物を固化して運搬することにより、陸路・海路輸送における不測の事故においても、ハロゲン化芳香族化合物を含有する液体媒体が流出又は漏洩するおそれがなくなる。これによりハロゲン化芳香族化合物処理工場までの陸上輸送路周辺の住民などの不安が減少する効果が期待できる。さらに万一固化した媒体が輸送時に漏洩したとしても、固化した状態であれば回収が容易であるため、液状物質のように環境中に広く散逸するおそれが非常に少ない。 By solidifying and transporting the halogenated aromatic compound according to the method of the present invention, the liquid medium containing the halogenated aromatic compound can be prevented from flowing out or leaking even in an unexpected accident in land and sea transportation. This can be expected to reduce the anxiety of residents around the land transportation route to the halogenated aromatic compound processing plant. Furthermore, even if the solidified medium leaks during transportation, it can be easily recovered if it is in a solidified state, and therefore there is very little risk of being dissipated widely in the environment like a liquid substance.
本発明の方法の具体的な実施の形態について以下に説明する。本発明は、以下に説明される態様に限られない。
例として、ハロゲン化芳香族化合物であるＰＣＢが溶解した絶縁油をゲル化して運搬する方法を説明する。高圧トランスなどに使用される絶縁油に、０．５ｐｐｍ程度あるいはそれ以上のＰＣＢが溶解していることがある。この絶縁油をＰＣＢ処理工場に運搬し、処理および廃棄する必要がある場合に、本発明の方法により安全に運搬することが可能となる。
Specific embodiments of the method of the present invention will be described below. The present invention is not limited to the mode described below.
As an example, a method for gelling and transporting insulating oil in which PCB, which is a halogenated aromatic compound, is dissolved will be described. PCBs of about 0.5 ppm or more may be dissolved in insulating oil used for high-voltage transformers and the like. When this insulating oil needs to be transported to a PCB processing plant for processing and disposal, it can be safely transported by the method of the present invention.
まず、ＰＣＢが溶解した絶縁油を固化する。固化は上述したとおり、油吸着材または固化剤を用いて行うのが最も便利で好ましい。種々の材料あるいは薬剤のうち、特にゲル化剤を用いることが特に好ましい。ゲル化剤として加熱型ゲル化剤を使用することも可能であるが、作業の便を考慮すると常温ゲル化剤を用いるのが好ましい。常温ゲル化剤として、ロジン系ゲル化剤が挙げられる。ロジン系ゲル化剤は、例えば荒川化学工業株式会社よりＲＧ−１００の商品名にて市販されている。かかるロジン系ゲル化剤を、該絶縁油の約１〜１０重量％、好ましくは２〜７重量％の濃度となるように添加して撹拌する。撹拌するうちに絶縁油に粘性が出てくるので、ここで撹拌を停止し、ゲル化を進行させる。これによりＰＣＢを含有する絶縁油がオイルゲルの形に変化する。ゲル化剤によりゲル化した絶縁油は、圧力をかけても油が再漏洩しにくく、特に好ましい。 First, the insulating oil in which PCB is dissolved is solidified. As described above, the solidification is most conveniently and preferably performed using an oil adsorbent or a solidifying agent. Of various materials or drugs, it is particularly preferable to use a gelling agent. Although it is possible to use a heated gelling agent as the gelling agent, it is preferable to use a room temperature gelling agent in consideration of the convenience of work. Examples of the room temperature gelling agent include rosin gelling agents. The rosin gelling agent is commercially available, for example, from Arakawa Chemical Industries, Ltd. under the trade name RG-100. Such a rosin-based gelling agent is added and stirred to a concentration of about 1 to 10% by weight, preferably 2 to 7% by weight of the insulating oil. During the agitation, the insulating oil becomes viscous, so the agitation is stopped here and the gelation proceeds. Thereby, the insulating oil containing PCB changes into the shape of an oil gel. An insulating oil gelled by a gelling agent is particularly preferred because the oil is difficult to leak again even when pressure is applied.
このように固化した絶縁油を、好ましくは密封可能な容器に封入して、運搬用車両、例えばトラック、運搬用鉄道、運搬用船舶などに積載し、ＰＣＢ処理工場まで運搬する。
吸蔵型の油吸着材を使用してかかる絶縁油を固化することが可能であるが、油吸着材に吸蔵された油は圧力をかけると再漏洩する場合があるので、圧力がかからない態様で運搬することが望ましい。
The insulating oil thus solidified is preferably sealed in a sealable container, loaded on a transportation vehicle such as a truck, a transportation railway, a transportation ship, and transported to a PCB processing factory.
It is possible to solidify such insulating oil using an occlusion type oil adsorbent, but the oil occluded in the oil adsorbent may leak again when pressure is applied, so it is transported in a mode that does not apply pressure. It is desirable to do.
本発明の運搬方法を実施するために、以下に液体媒体を常温ゲル化剤によりゲル化した実験例を説明する。本実施例は本発明の実施の態様の一部を記載したものであり、本発明の思想を制限するものと考えてはならない。 In order to carry out the transport method of the present invention, an experimental example in which a liquid medium is gelled with a normal temperature gelling agent will be described below. This example describes a part of the embodiment of the present invention, and should not be considered as limiting the idea of the present invention.
荒川化学工業株式会社より得たＲＧ−１００を用いて、ＰＣＢ含有高圧絶縁油のゲル化実験を行った。ＰＣＢ含有絶縁油は、ＰＣＢ（カネクロール１０００、鐘淵化学製）を高圧絶縁油（新日本石油製）に加え、ＰＣＢの濃度が２５ｐｐｍになるように調製した。 Using RG-100 obtained from Arakawa Chemical Industries, Ltd., a gelation experiment of PCB-containing high-pressure insulating oil was conducted. The PCB-containing insulating oil was prepared by adding PCB (Kanekuroru 1000, manufactured by Kaneka Chemical) to high-pressure insulating oil (manufactured by Nippon Oil Corporation) so that the concentration of PCB was 25 ppm.
ＰＣＢ含有高圧絶縁油３０ｇをサンプル瓶に採り、ここへＲＧ−１００を、当該絶縁油量の５重量％に相当する１．５ｇを添加し、攪拌した。２分〜３分で明らかな粘度増加が観察され、１０分経過後には、白濁し、完全にゲル化したことが認められた。サンプル瓶のふたを開け、開口部を下方に向けても流動する様子は認められず、完全にゲル化したことが確かめられた。この状態はその後１０日間放置しても何ら変化しなかった。 30 g of PCB-containing high-pressure insulating oil was taken in a sample bottle, and 1.5 g corresponding to 5% by weight of the insulating oil was added to RG-100 and stirred. A clear increase in viscosity was observed in 2 to 3 minutes, and after 10 minutes, it was confirmed that the solution became cloudy and completely gelled. Even when the lid of the sample bottle was opened and the opening was directed downward, no flow was observed, confirming complete gelation. This state did not change even after 10 days.
このように、ＰＣＢ含有高圧絶縁油を固体状態に変化させることが可能であることがわかった。本実施例にならい、ハロゲン化芳香族化合物含有媒体を固化し、好ましくはこれらを密閉可能な容器に封入し、陸路あるいは海路において安全に輸送することが可能である。 Thus, it was found that the PCB-containing high-pressure insulating oil can be changed to a solid state. According to the present embodiment, the halogenated aromatic compound-containing medium can be solidified, and preferably sealed in a container that can be sealed, and transported safely on land or sea.
本発明の方法は、ハロゲン化芳香族化合物を含有する液体媒体を固化して運搬するので、漏洩・流出のおそれなく処理工場まで運搬することが可能である。固化した媒体が万一漏洩した場合でも、回収が容易であり、環境中に広く拡散するおそれがない。これによりハロゲン化芳香族化合物の運搬ルート周辺住民の不安を低減することができる。 In the method of the present invention, since the liquid medium containing the halogenated aromatic compound is solidified and transported, it can be transported to a processing factory without fear of leakage or spillage. Even if the solidified medium leaks, it is easy to collect and there is no fear that it will diffuse widely into the environment. This can reduce the anxiety of residents around the transport route for halogenated aromatic compounds.
