Embodiment 1

[0054] In order to investigate the effect of this test method, blended fuel oils A, B, and C were used in the experiment. The temperature of the oil bath was set at 120°C. The gradient stabilization tube was placed in the oil bath to keep the temperature constant. After 12 hours of air flow, samples were taken to determine the first, The total potential sediment, acid value, density, and viscosity at the openings of 2, 3, 4, 5, and 6 are processed by formulas (1)-(8) to obtain A, B, and C heavy marine Blend the total potential sediment, acid value, density, viscosity of the upper and lower layers of the fuel oil. The experimental results are shown in Table 1.

[0055]

[0056] It can be seen from Table 1 that A and B oils are stable in properties, and C oils are less stable.

Abstract

The invention discloses a method for rapidly detecting the storage stability of fuel oil for heavy ships. The method comprises the following steps: filling a gradient viscosity tube having a special structure with a test oil product, and introducing an oxygen-containing gas to carry out accelerated oxidation; and respectively extracting the test oil product from different sampling openings, detecting the sampled test oil product, and processing all detected groups of data to obtain the property parameters of the fuel oil. The method can simulate the stability change of the fuel oil for heavy ships with time or being exposed to air in the whole process period of blending storage, sale, ship storage cabinet storage and combustion, and has the characteristics of fast measurement, good result accuracy, improvement of the timeliness of the detection process, and compensation for the gap in methods for detecting the storage stability of the fuel oil for heavy ships in China.

Description

technical field [0001] The invention belongs to a method for measuring the stability of fuel oil, in particular to a rapid detection method for the storage stability of heavy marine blended fuel oil or marine fuel oil. Background technique [0002] The low output of marine fuel oil in domestic refineries has a large gap with market demand, which seriously affects the development of my country's shipping industry. Using blending technology to blend some industrial waste oil into marine fuel oil can not only bring considerable economic benefits to Sinopec, but also effectively reduce environmental pollution. It is an effective way to improve the utilization rate of petroleum energy. However, driven by profit, low-quality marine fuel oil prepared from coal tar, waste engine oil, crude aromatics, vegetable oil and tire rubber oil was found in the circulation field. The mixing of these oils from complex sources into marine fuel oil will form unstable factors: asphaltene or sludg...
