How to automatically detect water soluble acid and alkali in oil



There are water-soluble acid and alkali in petroleum products, indicating that the acid is not completely neutralized or washed with water after alkali washing. These mineral acids and bases can corrode metal components in contact with them during production, use or storage. Water-soluble acids are highly corrosive to almost all metals, while bases are only corrosive to aluminum. When a water-soluble alkali is present in gasoline, the aluminum parts of the carburetor form a gel of aluminum hydroxide that blocks oil lines, filters and nozzles.

The presence of water-soluble acid and alkali in oil will promote the aging of oil. Because there are water-soluble acids and bases in the oil, the interaction of water and oxygen in the atmosphere and under the condition of heat, over time will cause oil oxidation, gelation and decomposition. So in the factory finished product analysis, even if it is found that there is a very small amount of water-soluble acid and base, are considered unqualified, can not leave the factory.

The determination of water-soluble acid and base generally uses GB/T259 "petroleum products water-soluble acid and base determination method", SH259C automatic wide range of water-soluble acid and base tester (Shandong Shengtai Instrument Co., LTD.) is designed and produced in strict accordance with this standard,

It is specially used for the determination of water soluble acid (pH) in lubricating oil, gasoline, solvent oil and other petroleum products. High degree of automation, only need to inject oil and water according to the standard, the instrument will be in strict accordance with the standard order of heating, oscillation, oil and water separation, display and print PH measurement results. The instrument improves working efficiency and test accuracy while reducing the user's contact with samples and reagents. Without manual measurement, only the sample is placed in the sample cup, the instrument will automatically carry out the process of injection, heating and oscillation, determination, drainage, display results and so on. Suitable for measuring liquid petroleum products, additives, grease, paraffin and water-soluble acid containing wax components, and widely used in petroleum, electric power, chemical, pharmaceutical, commodity inspection, scientific research, environmental protection and other fields.
