Abstract: The present invention relates to resid processing, particularly related to conversion of resid material with maximum recovery of lighter hydrocarbons. The invented process utilizes a novel scheme for integration of solvent de-asphalting and delayed coking processes to maximize the residue conversion to valuable products, with cleaner quality of middle distillates and fuel oil products, in comparison with other integrated solvent de-asphalting and delayed coking schemes. This process also has an additional flexibility to vary the recycle quantity, without impacting fractionator operation of the delayed coking section, which further enhances the product recovery and achieves maximum conversion of the resid feedstock, with minimum impact on liquid product properties.

Abstract: Present invention relates to a novel process for upgrading a residual hydrocarbon oil feedstock having a significant amount of Conradson Carbon Residue (concarbon), metals, especially vanadium and nickel, asphaltenes, sulfur impurities and nitrogen to a lighter more valuable hydrocarbon products by reducing or minimizing coke formation and by injecting fine droplets of oil soluble organo-metallic compounds at multiple elevations of the riser with varying dosing rates.
