Oil stability and compatibility analyzer

Overview

In the face of numerous existing and newly developed ultra-low sulfur fuel oils, it is necessary to comprehensively consider their stability and mixing compatibility characteristics. This situation may also exist with other fuels, including biofuels. By taking proactive measures and embracing new technologies, issues related to these features can be avoided.

DK PL010 seriesOil stability and compatibility analyzerIt is an instrument developed by Duke Tech for analyzing the stability and compatibility of asphaltene in heavy oil/crude oil. It complies with ASTM D7112 standard, ISO/PAS 23263, and CIMAC guidelines. This analyzer is used for blending optimization of crude oil, raw materials, heavy oil, and asphalt.

It can not only provide conventional stability parameters (solvent equivalent and P-value), but also output stability parameters that characterize the flocculation trend of asphaltene in oil products, which is crucial for describing the storage life and compatibility of heavy oil products.

Technical Solution

DK PL010 series from Duke Tech CorporationOil stability and compatibility analyzerIt is an easy-to-use, reliable, and fast analytical instrument that improves the profitability of refining processes by enabling refineries to select more economical crude oil mixtures without scaling risks.

The fast and automated analysis cycle saves work time and improves the efficiency of the testing process. With its automatic optical detection, DK PL010 seriesOil stability and compatibility analyzerCan provide users with more reliable results than point testing. DK PL010 seriesOil stability and compatibility analyzerBy measuring the compatibility parameters of different oil products, it is possible to predict their compatible mixing ratios. Even oil products without asphalt can measure their mixing parameters.

Unlike other similar analyzers, the DK PL010 seriesOil stability and compatibility analyzerCapable of measuring stability and compatibility parameters of oil products with extremely low asphalt content (as low as 0.05%). Usually, even low asphaltene content oils can experience compatibility issues, which can lead to blockages and cause serious problems during use. This analyzer is also suitable for analyzing fuels with high asphalt content.

Oil stability and compatibility analyzerMeasurement steps

● Preparation of mother liquor: Mix xylene with the oil sample to be tested. Weigh 20 grams of xylene and 40 grams of oil sample and place them in a mixing bottle. Shake the solution for 60 seconds.

● Sample packaging: Weigh 7.5 grams, 11.2 grams, and 15 grams of mother liquor respectively and place them in three sample cups, then place them on the sample turntable. The analyzer automatically prepares three different dilution ratios of oil and xylene mixture.

● Operation analysis: The analyzer automatically titrates with heptane. Using visible light scattering optical detection, the precipitation point of asphalt was detected on the titration curves (inflection points) of all three sample cups.

Output results: The analyzer will output a complete set of parameters, including stability P-value, solvent equivalence FR5/1, solubility mixing value SBN, and insoluble substance value IN.
