Abstract:
1. A method comprising: (a) a step of obtaining steam cracked tar, wherein (a) includes fractionating the effluent of a pyrolysis furnace to provide a bottoms product comprising steam cracked tar and to provide one or more products comprising light olefins selected from ethylene, propylene, and butenes, are separated in a primary fractionator, and isolating a bottoms product comprising tar from said fractionating; (b) at least one step of treating said steam cracked tar via solvent deasphalting to remove asphaltenes to provide a deasphalted tar; and (c) at least one step of hydrotreating said deasphalted tar to obtain a hydrotreated, deasphalted tar product; (d) separating a hydrocrackate from said hydrotreated, deasphalted tar product by fractionation, wherein (i) said hydrocrackate is obtained as bottoms product and (ii) said hydrocrackate is characterized as providing a viscosity and sulfur credit versus Bunker C Fuel; and (e) blending said hydrocrackate with Bunker Fuel to produce a compatible blend.
