1 Introduction
In the modern oil industry, petrol and paraffin-based products are extensively used in various fields. It is critical to know the quality of these products, including their viscosity, stability, corrosion resistance, and the presence of suspended solids. In order to measure these properties accurately, a variety of tests have been developed, including the determination of the creaminess, saponification value, and miscellaneous oil content of petrol and paraffin-based products. This paper will discuss the various test methods used to determine these properties.
2 Creaminess Test
The creaminess test measures the creaminess of petrol and paraffin-based products. This is done by measuring the foam formed by mixing a sample of the product with a measured amount of water. The foam is then allowed to stabilize, and the height of the foam is then measured. The resulting value is compared with previously established values, and the sample is given a rating from low to high creaminess.
3 Saponification Value
The saponification value is a measure of the ability of petrol and paraffin-based products to react with a basic solution of alkali. This is done by adding a sample of the product to a measured amount of the alkali solution and measuring the reaction time. The saponification value is then determined by comparing the reaction time to previously established values.
4 Miscellaneous Oil Content
The miscellaneous oil content of petrol and paraffin-based products is measured by adding a sample of the product to a beaker of clean water and allowing it to settle. The oil content is then measured by subtracting the amount of water remaining after the oil has settled from the amount of water originally added.
5 Conclusion
The creaminess, saponification value, and miscellaneous oil content of petrol and paraffin-based products can be measured by various test methods. The creaminess test measures the foam produced when the product is mixed with water, while the saponification value is determined by measuring the reaction time of the product with an alkali solution. The miscellaneous oil content is measured by subtracting the amount of water remaining after the oil has settled from the amount of water originally added. These tests allow for an accurate measurement of the quality of these products, and are essential for ensuring a safe and efficient operation of the modern oil industry.
