Abstract:
1. A method for estimating a content of particulates having a predetermined particle size or having a particle size less than the predetermined particle size in a slurry with solid particles dispersed in hydrocarbons including a wax, the method comprising, based on a correlation between a visible light transmittance and a content of solid particles having the predetermined particle size or having a particle size less than the predetermined particle size at a temperature at which hydrocarbons including a wax are liquefied when the solid particles having the predetermined particle size or having a particle size less than the predetermined particle size are dispersed in the hydrocarbons: estimating a content of particulates having the predetermined particle size or having a particle size less than the predetermined particle size in the slurry from a visible light transmittance of a supernatant part when the slurry is left to stand at the temperature at which the hydrocarbons including a wax are liquefied.
