Abstract

See full text

A method for determining a relationship between the ratio of solvent power to critical solvent power and the threshold light paraffin content of a hydrocarbon fluid is provided. The method comprises:

    dividing the plurality of hydrocarbon fluids into subgroups, based on the ratio of solvent power to critical solvent power;for each of the subgroups, determining the threshold light paraffin content, said threshold light paraffin content being the light paraffin content of the hydrocarbon fluids at the point at which the fouling tendency of the hydrocarbon fluids exceeds a fouling threshold; anddetermining a relationship between the ratio of solvent power to critical solvent power and the threshold light paraffin content.
