【発明の詳細な説明】 〔産業上の利用分野〕 本発明はバナジウムの簡易分析法に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a simple method for analyzing vanadium.

なってきた。In order to reduce fuel consumption and increase demand for light oil, heavy oil used as fuel for boilers and marine engines is produced by extracting light oil from atmospheric distillation residual oil and vacuum distillation residual oil by catalytic cracking or thermal cracking. Increasingly, inferior heavy oil, which is a mixture of light oil and oil, is becoming more common.
特に陸上の公害規制強化によりこれら粗悪重油の用途に
おける大型舶用ディーゼル機関や大型ボイラの燃料油の
占める割合は増大しつつある。In particular, due to the tightening of pollution regulations on land, the proportion of fuel oil for large marine diesel engines and large boilers in the use of these inferior heavy oils is increasing.

し、的確な対策をたてる必要がある。These poor-quality heavy oils are enriched with sulfur and metals such as vanadium and nickel in crude oil, and many problems occur due to these properties. When the vanadium content increases in fuel oil, high-temperature corrosion occurs due to the formation of vanadium compounds with low melting points. In order to prevent these problems from occurring, it is necessary to understand the amount of vanadium in the fuel oil used and take appropriate measures.

定精度は良いが装置が複雑かつ高価であり、和尚な化学
的知識と時間を要する欠点がある。At JP Kogyo and ABTM, analysis of vanadium in fuel oil is carried out by ashing, dissolving the ash in acid, and then using spectrophotometry or atomic absorption spectrometry, but although these methods have good measurement accuracy, The disadvantage is that the equipment is complex and expensive, and requires sophisticated chemical knowledge and time.

By filling the EIR measurement cell with a certain amount of fuel oil and immersing the cell in a liquid nitrogen dewar, the rotation effect of the solvent can be suppressed and a sensitive spectrum can be obtained. You can know the value. Figure 2 shows the results. Comparison with FIG. 1 of Example 1 shows that favorability analysis is possible.
