2. Description of the Related Art Conventionally, for example, in the event of a marine accident on a large ship or an oil spill from a tanker, a technique for recovering a large amount of oil spilled onto the sea, for example, using highly lipophilic polypropylene or porous fiber as a raw material. There is known a technique in which an oil-absorbing mat is dropped onto a contaminated sea, and oil is adsorbed and collected.

[0003] However, such an oil-absorbing mat has a problem that when the oil-absorbing mat is collected, the oil drips from the mat to deteriorate the collection efficiency. Since there is a problem that workers and ships become sticky with oil, a technique has been proposed in which instead of an oil-absorbing mat, a powdered gelling material is sprayed, and the gelling material is used to gel the oil to recover the oil. . At this time, the gelled coagulated material can be collected neatly without touching the hand or oil because the oil does not adhere to the hand even if touched by hand, but the powder is extremely light and it is difficult to spray it efficiently. There are, for example, those in which a plurality of the oil absorption mats are stacked and a powder gelling material is interposed therebetween,
Also, a powdered gelling material is solidified into a sheet or mat, or a powdered gelling material is packed in a net-shaped bag as disclosed in Japanese Patent Application Laid-Open No. Hei 7-136501. ing.

However, as described above, the method of stacking a plurality of oil-adsorbing mats and sandwiching the gelling material of the powder therebetween has a waste in exhibiting the oil-absorbing ability of the gelling material of the powder inside. In addition to the fact that the oil-adsorbing mat is exposed on the surface in addition to the fact that the oil-adsorbing mat is exposed, the soiling of workers, ships, etc. was not much different from the case of using the oil-adsorbing mat alone. Also, when the powdered gelling material is solidified into a sheet or mat, the surface area in contact with the oil is reduced as compared to keeping the same amount in the powder, and the processing capacity tends to decrease. there were. Also, with regard to the technology of packing a gelled powder material in a net-shaped bag, usually, when the gelled powder material is gelled and solidified, the volume expands several times to several tens times, so Unless the bag is formed large and the space in the bag is not allowed, there are problems such as breakage of the bag and insufficient gelation.
For this reason, it is necessary to previously fill the space in the bag with the gelling material with a margin, but in this case, the gelling material is unevenly distributed in a part of the space in the bag at the stage of charging the bag at the contamination site. For example, there is a problem that even if it is desired to uniformly distribute the density on the contaminated sea, the dispersion becomes uneven and the treatment cannot be performed efficiently.

Here, as the gelling material 2, in the case of the embodiment,
Polynorbornene, which is known as a super oil-absorbing polymer, is a white powder at a glass transition point of about 35 ° C. at room temperature, and has a specific gravity of 0.55 to 0.65.
It is lighter than water and does not dissolve in water.

When the gelling material 2 comes into contact with petroleum hydrocarbons such as crude oil, heavy oil, light oil, gasoline, kerosene and lubricating oil, and chemical products such as toluene and xylene, it gels and solidifies, Even when oil and oil are mixed, only the oil is mainly gelled and solidified. Once absorbed, the hydrocarbon compounds are permanently bound and do not leach out and do not biodegrade. The gelled solids can be easily recovered because they float on the water surface, and the solidified hydrocarbon compounds can be incinerated because of their low moisture content.

By the way, the following table shows the results of testing the processing ability of the gelling material 2 for several kinds of oils. The test method was as follows. Crude oil, low sulfur type crude oil, heavy oil, light oil, gasoline, kerosene
After adding 30 g of seed oil, 1 g of gelling material 2 was added in each case. At this time, the surface area of the beaker was 25.14 square inches. After 5 minutes, 15 minutes, 30 minutes and 60 minutes, the gelled product was taken out, placed on a filter and drained for 30 minutes, and the gelation strength, water content and oil absorption were measured.

[0015] As a result, the gelling strength is initially weak, but becomes harder with the passage of time.
It became the hardest in 30 minutes. In addition, it was also found that the oil of (1) solidified in a large lump of colloidal form, but the oil of (1) became slightly smaller. However, in each case 15-30
The lumps were of such a degree that they could be easily recovered in minutes, and the surface was not sticky in any case, and no oil was attached even when touched by hand. Further, it was also found that the oil absorption amount did not increase after 30 minutes had elapsed, and that the oil absorption was maximal within 30 minutes.

Next, the packaging material 3 is water-soluble paper in the case of the embodiment. This water-soluble paper uses Desolvo (Mishima Paper Co., Ltd.), which is a paper in which molecules are dispersed in water. Then, for example, a water-soluble polymer or the like is laminated on the inner surface side of the packaging of the packaging material 3 so as to increase airtightness. This is because the oxidative deterioration of the gelling material 2 is relatively fast, so that the gelling material 2 is hardly contacted with outside air.

In the embodiment, the gelling material 2 of about 100 to 200 g is packaged as one pack. For example, in the embodiment of FIG. 1, the length of one side is 20 to 50 cm and the thickness is 3 to 15 mm.
It is in as to the extent of a rectangular shape.

The oil gelling material 1 as described above is loaded into the oil contamination site D from a ship or an aircraft when oil contamination occurs on the sea as shown in FIG. 2, for example. Then, the packaging material 3 comes into contact with the lower layer of water and melts out due to the action of the momentum or the wave at the time of charging, and the gelling material 2 inside is scattered to gel the oil. At this time, for example, if the oil-gelling material 1 is in the form of a flat plate as shown in FIG. 1, the gelling material 2 can be scattered on the oil film with a uniform thickness, and the treatment can be performed extremely efficiently. After about 15 to 30 minutes, a colloidally solidified gel is formed, and can be easily recovered by processing it by scooping it with a net or the like. At this time, even if the gelled material is touched by hand, it does not become sticky and does not stain the recovery boat or the like. Since the recovered gelled material has a low water content, it can be incinerated, for example.

In addition, especially when charged from a ship, a flat plate as shown in FIG. 1 is advantageous from the viewpoint of uniformly dispersing the density, for example, when charged from a ship. As described above, the packaging material 3 by the action of the force Toka wave when turned is dissolved out by touching the lower aqueous exact location
In order to increase the dissolution rate or the like , sand, soil, etc. are mixed into the inside of the packaging material 3 as necessary, and a part or all of the material is positively settled through an oil film so as to be exposed to water. good. And even if in this way sink deeper into the water, the packaging material 3 gelling material 2 out dispersion by melting floats lighter than water, it gel in contact with the oil.

I can do it. For this reason, oil processing can be performed extremely efficiently. In addition, the surface of the gelled material does not become sticky with oil, and the oil does not adhere even if touched by hand, so that the collecting operation can be performed easily and neatly.
