ABSTRACT:
A method for assaying incompatible sediment in a blended heavy fuel oil is provided. The method is based on measuring total light absorption at 1600 nanometers wavelength, for example, of two or more samples blended to different viscosities, at least one such sample being at specification viscosity. The method may be used to control visbreaker severity so as to reduce the large ERT safety margin commonly used by refiners.
