Description of the Related Art Various types of oils such as fuel and machine oil are used in factories and business sites of various manufacturing industries (hereinafter referred to as factories, etc.), but these oils are not single components. A mixture of multiple oil types (hereinafter referred to as a mixed oil)
There are many. When using these mixed oils in factories,
In rare cases, a small amount of mixed oil may leak and enter the drainage system due to some failures in the facilities or the like.

の排出を阻止する必要がある。If the mixed oil leaks into the drainage system, it is eventually discharged from the drain outlet to the outside of a factory or the like, possibly causing water pollution outside the region. Therefore, the mixed oil component in the wastewater is specified. However, it is necessary to quickly identify the leakage route and to prevent discharge to the outside.

開発が望まれていた。[0004] As a method of specifying the components of the mixed oil in the wastewater, conventionally, the oil extracted by the solvent is separated and collected into a single component by various types of chromatography, and then each fraction is subjected to infrared spectroscopy or mass spectrometry. Identify the composition by analytical method,
Finally, there was something that specified a mixed oil. However, in this method, a long time is required for the analysis, and the identification of the leakage path of the mixed oil is delayed. Therefore, it has been desired to develop a method for quickly identifying the components of the mixed oil.

相関が得られた。DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the sulfur concentration of a mixed oil itself having various sulfur concentrations (hereinafter referred to as "source oil"), and carbon tetrachloride from a simulated wastewater obtained by adding approximately 1 ppm of base oil to seawater. The relationship of the sulfur concentration of the extracted mixed oil is shown. The measurement of the sulfur concentration was performed using the combustion method specified in JIS K2541. Regarding the sulfur content of the mixed oil in the simulated wastewater, the total mass of the sulfur contained in the extracted carbon tetrachloride was calculated by measuring the carbon tetrachloride extraction material concentration specified in JIS K 0102 by the OCB equivalent amount. Divided by the total mass of the mixed oil calculated as FIG. 1 shows an extremely good correlation. By measuring the sulfur content of the mixed oil in the wastewater, the sulfur content of the base oil can be estimated. Based on this measurement, a table of the sulfur concentration of the mixed oil used in each process or facility with the factory is created using the simulated wastewater. In addition, as for the simulated drainage, a drainage prepared using factory drainage was also used, and a good correlation was similarly obtained.

もの（ＦＴ−ＩＲ）が好ましい。FIG. 2 shows an infrared absorption spectrum of sesame oil, and FIG. 3 shows an infrared absorption spectrum of a mixed oil extracted from simulated wastewater to which sesame oil has been added using carbon tetrachloride.
In the case of the extract from the simulated wastewater, the minute absorption peak has disappeared, but the main absorption peak is clearly observed at the same wave number as compared with the spectrum of the original oil. The infrared spectroscopy was performed by the KBr tablet method. The spectrometer to be used is not particularly limited, but a Fourier transform type (FT-IR), which is not a dispersive type but can be measured in a short time, is preferable.

こで使用する混合油の種類に基づき作成する。Similarly, simulated wastewater is prepared for various types of mixed oils, extracted with carbon tetrachloride, measured for infrared spectrum, and the wave number at which the main absorption peak appears is used. The oil mixture to be used is roughly classified in advance. For example, Table 1 shows mineral oils, fatty acid esters, phosphate esters and glycols used in steelworks.
The wave number of the main absorption peak is shown. Note that the major classification of the mixed oil is not limited to this example, but is created for each factory or the like based on the type of the mixed oil used there.

For each classification, two types of tables are prepared: the name of the mixed oil, the wave numbers of all major infrared absorption peaks, the range of the sulfur concentration, and the second table that describes the use process (equipment).

Follow 102. Extract the mixed oil in the collected sample with carbon tetrachloride, measure the infrared absorption spectrum of the obtained extract, and confirm the wave number of the main absorption peak. In addition, the sulfur concentration of the leaked mixed oil is separately measured using a part of the extract.

を図4に示す。After confirming the major classification of the mixed oil corresponding to the wave number of the maximum absorption peak in the first table, all major major oils are identified in the second table for the major classification (when there are a plurality of them, all of them). A mixed oil is specified from the absorption peak wave number and the sulfur concentration range, and a process (equipment) using the mixed oil is specified. FIG. 4 shows a flowchart of the method of the present invention.

漏洩経路の特定を速やかに行なうことが可能になる。In the method of the present invention, when a plurality of mixed oils having the same absorption peak wave number and the same sulfur content range exist, it is difficult to completely identify the type of leaked mixed oil. Since the number of oil types can be reduced to a small number, it is also possible to quickly specify a leakage path.

合油種を特定することが可能である。Table 2 shows the main absorption peak wavenumbers and sulfur content ranges of various types of mixed oils of which the major category is mineral oil. As is evident from Table 2, even for mixed oils belonging to the same major category, the corresponding mixed oil types can be specified because of differences in sulfur content.

As a result, significant effects can be obtained not only in equipment preservation but also in environmental preservation.
