摘要： A method for determining a sludge content in a heavy hydrocarbon oil and a device therefor are disclosed. The method comprises measuring absorbances of a heavy hydrocarbon oil sample, having an oil film thickness selected form a range of from about 0.01 to 5 mm, at two different wavelengths selected from the visible light region of from 500 to 1000 nm and determining a sludge content of the sample oil by comparing two measured absorbances according to the relationship between known sludge contents and absorbances at the two wavelengths. The device comprises a light source (2), a cell (10) for a sample oil, a two-wavelength absorbance detector (1) containing two interference filters (3) and two light-current transducers (4), and a computing means (16) for converting the current values obtained into a sludge content. The method and device provide a means for rapid and precise determination of sludge contents in heavy hydrocarbon oils.
