A method for processing bitumen froth to produce a diluted bitumen product having a reduced water and solids content is provided, comprising: adding a sufficient amount of water to the bitumen froth and mixing the bitumen froth and water to form a froth/water mixture; diluting the froth/water mixture with naphtha to form a diluted froth; and separating the water and solids from the diluted froth to produce the diluted bitumen product.

An integrated method for mesophase pitch and petrochemicals production. The method including supplying crude oil to a reactor vessel; heating the crude oil in the reactor vessel to a predetermined temperature for a predetermined amount of time; reducing asphaltene content in the crude oil by allowing polymerization reactions to occur in the reactor vessel at an elevated pressure in the absence of oxygen; producing a three-phase upgraded hydrocarbon product comprising gas, liquid, and solid hydrocarbon components, where the liquid hydrocarbon component comprises deasphalted oil and the solid hydrocarbon component comprises mesophase pitch; separating the gas, liquid, and solid hydrocarbon components; directly utilizing the liquid hydrocarbon component for petrochemicals production; and directly utilizing the solid hydrocarbon component for carbon artifact production.
