Pour point detection |
摘要 |
The present invention relates to an apparatus and process for estimating the pour point of a hydrocarbon oil. The pour point of hydrocarbon oil gives an indication of its low temperature properties, and is determined according to the time-consuming procedures set out in the American Society of Testing and Materials (ASTM) test D-97. The present invention generally provides a convenient means to estimate the pour point of a hydrocarbon oil, by directing a flow of pressurized gas towards a sample of the oil, and determining the warmest temperature at which the gas flow does not cause a substantial surface wave on the oil surface.
