Embodiments of the disclosure provide a visbreaking system and method for upgrading heavy hydrocarbons. A heavy hydrocarbon feed is introduced to a furnace to produce a soaker feed stream. The soaker feed stream is introduced to a soaker to produce a soaker effluent stream. The soaker effluent stream is introduced to a fractionator to produce a visbreaker distillate stream and a visbreaker residue stream. The visbreaker residue stream and a water feed are introduced to a supercritical water reactor operated at supercritical conditions of water to produce an effluent stream. The effluent stream is introduced to a flash column to produce a gas phase stream including water and a liquid phase stream including water. A portion of the liquid phase stream and the heavy hydrocarbon feed is combined. Optionally, a portion of the gas phase stream and the heavy hydrocarbon feed is combined. Optionally, a portion of the gas phase stream is introduced to the fractionator.

Embodiments of the present invention include a novel continuous or semi-continuous process which results in the partial or total improvement of heavy oil. The improvement of the heavy oil is a result of thermally heating the oil at an interval where visbreaking occurs, thereby reducing a viscosity of the heavy oil. The core of the heating step occurs through a heating apparatus of the packed bed type including superparamagnetic, paramagnetic, and/or magnetic materials.

The present invention discloses a process and an apparatus for conversion of waste plastic pyrolysis oil into value added products, wherein, the pyrolysis oil is produced from waste plastics by utilizing HCGO as a preheating stream. The process and apparatus as disclosed improves the conventional DCU process in terms of liquid, gaseous yields and reduction in coke yields and without disturbing the hardware of the conventional process along with energy efficient production of pyrolysis oil. The present process and apparatus include a delayed coking process and a system for the delayed coking process which involves the integration of delayed coking system with pyrolysis section and utilization of produced pyrolysis oil by co-processing it with residual heavy hydrocarbon feedstock.

A process for treating a heavy oil by heating a feedstock comprising a heavy oil in order to separate from the heavy oil a first fraction. The first fraction contains no more than 25% of the total number of acid groups of the heavy oil. A second fraction contains at least 75% of the total number of acid groups of the heavy oil. The second fraction then is treated under conditions that provide a heavy oil that has a total acid number, or TAN, that does not exceed 1.0 mg KOH/g, or is at least 50% lower than the total acid number prior to treatment, an olefin content that does not exceed 1.0 wt. %, and a p-value of at least 50% of the p-value of the heavy oil prior to treatment, or a p-value that is at least 1.5.

The present invention relates to a process and system for complete conversion of crude oils by integrating delayed coking process, high severity catalytic cracking process and naphtha cracking processes along with olefin recovery section, aromatic recovery section and gasifier section to maximize the crude oil conversion to valuable products like light olefins, aromatics and chemicals.

The present application provides a method and a system for recycling a polymer. The method includes introducing polymer into a primary melting extruder, producing a polymer melt that is combined with a fluid oil to at least partially dissolve the polymer melt. A secondary mixing extruder mixes these to form a polymer solution that is introduced into a refinery oil stream, producing a polymer-comprising oil stream, which is fed into a refinery process unit. The system includes a primary melting extruder for forming a polymer melt from polymer. A secondary mixing extruder receives the polymer melt. One or more hydrocarbon inflow conduits for providing a fluid oil to the primary melting extruder and/or the secondary mixing extruder are configured to form a polymer solution from the fluid oil and the polymer melt. There is a feed system outlet for feeding the polymer solution to a refinery oil stream.
