摘要： A method for determining an asphaltene yield curve and an asphaltene flocculation point includes obtaining a crude oil sample and measuring an optical spectrum of the crude oil sample. A titrant is then mixed with the crude oil sample at different concentrations. At each concentration, precipitated asphaltenes are filtered from the mixture and the optical spectrum of the filtrate is measured. The optical spectrum of the filtrate is then subtracted from the optical spectrum of the crude oil sample. A fractional asphaltene precipitation is determined for each concentration of titrant. A flocculation point is determined corresponding to an inflection point in the fractional asphaltene precipitation for each concentration of titrant.

摘要： A method and apparatus for analyzing solubility of asphaltenes of a hydrocarbon fluid sample involves a sequence of operations including: i) performing microfluidic mixing operations that form a mixture that includes the hydrocarbon fluid sample, a solvent that dissolves asphaltenes and a precipitant that precipitates asphaltenes; ii) using microfluidic processes that result in precipitation of asphaltenes from the mixture resulting from i); iii) performing microfluidic filtering operations that remove precipitated asphaltenes resulting from ii) and passes permeate; and iv) performing optical spectroscopy on the permeate resulting from iii). The operations of i)-iv) can be repeated over iterations that vary the amount of solvent relative to the precipitant in the mixture. These iterations can cause varying fractional precipitation of asphaltenes in each given iteration.
