Abstract
The present disclosure relates to an apparatus and a method for measuring miscibility in oil using back titration. The apparatus includes: a flocculation solution storage unit; a flow cell including a UV transmitting member; a dissolving agent storage unit; a UV irradiation unit; and a measurement unit, wherein: a flocculation solution is stored in the flocculation solution storage unit; the flocculation solution circulates between the flocculation solution storage unit and the flow cell; the measurement unit measures the UV transmittance of the flocculation solution while the dissolving agent in the dissolving agent storage unit is supplied to the flocculation solution storage unit; the miscibility in the oil is calculated from the amount of dissolving agent supplied and a change in the UV transmittance measured by the measurement unit; and the miscibility is calculated based on a time point when the slope of increase in the UV transmittance changes.
