Are recent improvements to FCC cyclone technology adequate enough to lower solids concentration in slurry oil down to a level (e.g., < 250 ppm) that the slurry oil can be sold without need for filtering?

It is a matter of energy balance. Removal of more very fine particles requires more energy expenditure in the cyclones, which equates to more air compressor horsepower and more wet gas compressor horsepower. Entropy strongly indicates slurry filtration is far lower energy cost.
Years ago, one enterprising major oil company sold slurry as 'burner tip cleaning oil'.
