    摘要: A method and a device for determination of the stability or storability of oil, wherein the stability of oil is determined by measuring the intensity of light scattering from the oil surface, when an asphalteneflocculating liquid is added to the oil sample for determining the stability of the oil. In an advantageous embodiment of the method the intensity of scattered light is directed onto the surface of the oil sample by using a suitable prism. The invention allows implementation of a fully automatically operating analyzer for determining the stability of oil. A closed measuring system is brought about that solves the explosion protection problem which is important in oil refining.

    摘要: The invention concerns a method and an apparatus for determination of the cloud point of oil. In the method according to the invention the cloud point is determined from a turning point on the oil cooling curve. The method of the invention may be realized in an apparatus comprising a cooling jacket for cooling the oil sample, a measuring space essentially shaped as oppositely located cones, a temperature indicator for determination of the oil cooling curve. With the invention the cloud point of oil can be determined quickly and reliably, the measuring cell of the invention allows a very high degree of exactitude in measurements, the measurement results are well reproducible and the invention makes it possible to bring about a method and an apparatus allowing a fully automatic operating analyzer for determination of the cloud point of oil.
