【発明の詳細な説明】 〔産業上の利用分野〕 本発明はプラントに付着した炭化物等の汚れを洗浄除去
するためのプラント用洗浄剤に関する。TECHNICAL FIELD The present invention relates to a plant cleaning agent for cleaning and removing stains such as carbides attached to a plant.
物理的あるいは化学的に過酷な条件で使用されるプラン

より運転が困難になつたり、時にはプラント自体を更新
する必要さえ生じる。有機物を扱うプラントにおいては
強固な炭化物の発生する場合も数多くある。これらの炭

力を利用したり人手によつてかき取つたりするために多
大の費用を要したり、場合によつてはプラント自体又は
その一部（例えば内部充填物等）を更新する必要さえ生
じていたのが実情であつた。In plants that are used under severe physical or chemical conditions, strong dirt often accumulates and accumulates, which makes it difficult to operate and sometimes even requires renewal of the plant itself. There are many cases where strong carbides are generated in plants that handle organic substances. These carbides often harden and adhere strongly so that they cannot be easily removed by washing with a solvent or conventional detergents. When these carbides accumulate inside the plant, the plant operation must be stopped for a long time in order to remove these contaminants, and it costs a lot of money to use mechanical power or scrape by hand. In reality, it was necessary or even necessary to renew the plant itself or part of it (for example, internal packing).
プラント自体は言うに及ばず、内部の充填物も非常に高
価な物が多いので、これらを簡単に洗浄し再度使用する
事が要望されている。従つて、プラントに付着した強固
な付着汚れ、特に炭化物汚れを容易に洗浄除去できる洗
浄剤が切望されていた。Not only the plant itself, but also the filling materials inside are often very expensive, so there is a demand for easy cleaning and re-use. Therefore, there has been a long-felt need for a cleaning agent that can easily remove strong adherent dirt, especially carbide dirt, that has adhered to the plant.
本発明者等はかかる洗浄剤を提供すべく鋭意検討を行つ
た結果、次亜塩素酸塩がかなり広範囲の種類の炭化物に

とも見出し、本発明を完成した。As a result of intensive studies to provide such a cleaning agent, the present inventors have found that hypochlorite has an excellent cleaning effect on a wide variety of carbides. In addition, plants are usually made of metal, and hypochlorite is very corrosive to metals, so corrosion may shorten the life of the plant. It has also been found that the combined use of and prevents the corrosion of metal, and completed the present invention.
従つて、本発明は、次亜塩素酸塩及び水溶性アミンを含

するとプラント本体の腐食の恐れがない。The method for cleaning the soil of the plant using the cleaning agent of the present invention is appropriately selected depending on the spot where the soil is attached, the shape and material of the plant, the purpose of cleaning, and the like. That is, in the case of the glass fiber reinforced resin or the glass lining, which has no fear of corrosion at all, it is possible to circulate and stir in the plant. When the internal components of the plant can be taken out, such as the rectification tower or the packing of the reactor, there is no risk of corrosion of the plant body if taken out to the outside and washed in a separate washing tank.
本発明洗浄剤の必須成分である次亜塩素酸塩はかなり強

て良好な洗浄作用を示すものと考えられる。Hypochlorite, which is an essential component of the cleaning agent of the present invention, is a fairly strong oxidizer, and it acts to cut the weak part of organic matter or change the terminal to carboxylate, thereby improving the adhesion of carbides. It is considered that the reduced desorption shows a good cleaning action on the carbide.
本発明の洗浄剤は、従来洗浄が困難とされていたプラン

ことができ、しかもプラントを腐食しないという利点を
有する。The cleaning agent of the present invention has an advantage that it is possible to remove plant stains, especially carbide stains, which have been conventionally difficult to be washed, by a simple washing operation, and the plant is not corroded.
次に実施例により本発明をさらに詳細に説明するが本発

不明である。Example 1 Model Stain Cleaning Test (Model Stain) A model stain was prepared as follows for a cleaning test in a laboratory. 2 g of p-toluenesulfonic acid was added to 200 g of oleic acid, and the mixture was heated with stirring at 250 ° C. for 48 hours in a nitrogen atmosphere. The obtained product is a blackish brown tar-like substance, which is a product of repeated complicated polymerization and metathesis, and its structure is unknown.
（試験方法） 約１００℃で融解させたモデル汚れに市販ステンレス鋼
片（50×150×0.5mm）を浸漬し、汚れがなるべく薄く均
一になる様にガラス棒で展着させる。(Test method) A commercially available stainless steel piece (50 x 150 x 0.5 mm) is immersed in model stains melted at about 100 ° C and spread with a glass rod so that the stains are as thin and uniform as possible.
この試験片を各種洗浄液約３００ｍに、８０℃で３０
〜６０分間浸漬し、汚れの除去される状況を目視で観察
し、５段階に評価した。This test piece was washed with various cleaning liquids of about 300 m at 80 ° C for 30 minutes.
It was immersed for -60 minutes, and the condition of removal of stains was visually observed and evaluated in 5 levels.
評価結果を表１に示す、評価は数字の多い程良い事を示

である。The evaluation results are shown in Table 1. The larger the number, the better the evaluation. Neoperex F-65 is sodium alkylbenzene sulfonate, and Emulgel 913 is polyoxyethylene nonylphenyl ether, both products of Kao Soap Co., Ltd.
表１から本発明品の顕著な洗浄効果が判る。尚、洗浄中
にpHが低下する傾向があり、洗浄の寿命を延ばすには、
カセイソーダの濃度がある程度高い方が良い様である。From Table 1, the remarkable cleaning effect of the product of the present invention can be seen. In addition, the pH tends to decrease during cleaning, and in order to extend the life of cleaning,
It seems that the concentration of caustic soda should be high to some extent.

使用し、洗浄液に浸漬し、６０℃に３日間保持し重量減
量を測定した。 Example 2 Corrosion Test A test piece of SUS316L having a surface area of 15 cm 2 (30 × 25 × 0.5 mm) was used, immersed in a cleaning solution and kept at 60 ° C. for 3 days to measure the weight loss.
洗浄液は次亜塩素酸ナトリウム３％、カセイソーダ２％
（他は水）をベース液とし、各種水溶性アミンを添加し
た。結果を表２に示す。本発明品では腐食量が約半分に
減少することが表２から判る。Cleaning solution is 3% sodium hypochlorite, 2% caustic soda
Various other water-soluble amines were added to the base liquid (others were water). The results are shown in Table 2. It can be seen from Table 2 that the amount of corrosion is reduced to about half in the product of the present invention.
実施例３ 高級脂肪酸（Ｃ6〜Ｃ18，ヤシ脂肪酸）の連続蒸留塔
で、長期間の運転により塔内の流動効率低下が認めら

のと判つた。 Example 3 higher fatty (C 6 -C 18, coconut fatty acid) in a continuous distillation column, the flow efficiency reduction in the tower was observed with long-term operation, operational efficiency came decreased. It was found that this was due to the bad influence of tar-like and carbide-like stains adhered to the distillation column packing in large amounts.
そこで塔内の充填物（材質SUS316）を取り出し、予めジ
エツト水で予備洗浄した後、別途設置した洗浄槽にて、
本発明の洗浄剤を用い、これらの洗浄を実施した。Therefore, the packing (material SUS316) in the tower is taken out, pre-cleaned with jet water in advance, and then in a separately installed cleaning tank.
These cleanings were performed using the cleaning agent of the present invention.
洗浄槽は直径１ｍ、深さ1.5ｍのタンクで、攪拌の為洗
浄液の循環系を備えている。洗浄装置はSUS304を使用し
た。The cleaning tank is a tank with a diameter of 1 m and a depth of 1.5 m, and is equipped with a circulation system for the cleaning liquid for stirring. The cleaning device used was SUS304.
洗浄液としては、次亜塩素酸ナトリウム３％（有効塩素
分約３％）、イソプロパノールアミン0.1％、カセイソ
ーダ0.5％の組成のものを用いた。洗浄液を循環攪拌し

重量で評価した。As the cleaning liquid, one having a composition of sodium hypochlorite 3% (effective chlorine content about 3%), isopropanolamine 0.1% and caustic soda 0.5% was used. After the cleaning liquid was circulated and stirred, the cleaning liquid was washed at a temperature of 60 ° C. for 3 hours, then the packing was taken out from the cleaning tank and washed with water. The washing condition was evaluated visually and by weight.
大抵の充填物（単位重量約15〜20kg）は１回の洗浄工程
で殆ど完全に洗浄出来たが、一部不完全な物は上記の過
程を適宜繰り返すことにより殆んど完全に洗浄出来た。
洗浄された充填物は新品のステンレスと同様の銀白色光
択の表面が得られた。被洗浄物に対する金属腐食は目視
で殆んど認められなかつた。Most packings (unit weight: about 15 to 20kg) could be cleaned almost completely in one cleaning step, but some incomplete packings could be cleaned almost completely by repeating the above process. .
The washed fillings had a silver-white selective surface similar to new stainless steel. Almost no metal corrosion was visually observed on the object to be cleaned.
