Abstract: Self-compatible heavy oil streams are produced from converted and/or desulfurized fractions. In a preferred embodiment, an incompatibility stream is added to the converted and/or desulfurized stream to reduce the solubility number of the stream. After using a water wash to remove incompatible material, a lighter fraction is removed from the stream to increase the solubility number.

Abstract: Methods and systems for reducing fouling, including particulate-induced fouling, in a hydrocarbon refining process including the steps of providing a crude hydrocarbon for a refining process and adding an antifouling agent containing a polymer base unit and a polyamine group to the crude hydrocarbon are provided. The antifouling agent can be obtained by converting a vinyl terminated polymer, such as polypropylene or poly(ethylene-co-propylene), to a terminal acyl containing functional group, followed by reacting the terminal acyl containing functional group with a polyamine compound.

Abstract: This invention relates to a process for the selective conversion of vacuum gas oil. The vacuum gas oil is treated in a two step process. The first is thermal conversion and the second is catalytic cracking of the products of thermal conversion. The product slate can be varied by changing the conditions in the thermal and catalytic cracking steps as well as by changing the catalyst in the cracking step. The combined products from thermal and catalytic cracking are separated in a divided wall fractionator.

Abstract: The present invention relates to a process for the selective conversion of hydrocarbon feed having a Conradson Carbon Residue content of 0 to 6 wt %, based on the hydrocarbon feed. The hydrocarbon feed is treated in a two-step process. The first is thermal conversion and the second is catalytic cracking of the products of the thermal conversion. The present invention results in a process for increasing the distillate production from a hydrocarbon feedstream for a fluid catalytic cracking unit. The resulting product slate from the present invention can be further varied by changing the conditions in the thermal and catalytic cracking steps as well as by changing the catalyst in the cracking step.

Abstract: The present invention relates to an improved delayed coking process. A coker feed, such as a vacuum resid, is treated with (i) a metal-containing agent and (ii) an oxidizing agent. The feed is treated with the oxidizing agent at an oxidizing temperature. The oxidized feed is then pre-heated to coking temperatures and conducted to a coking vessel for a coking time to allow volatiles to evolve and to produce a substantially free-flowing coke. A metals-containing composition is added to the feed at at least one of the following points in the process: prior to the heating of the feed to coking temperatures, during such heating, and/or after such heating.

Abstract: A heavy residual petroleum feed boiling above 650° F.+ (345° C.+) is subjected to membrane separation to produce a produce a permeate which is low in metals and Microcarbon Residue (MCR) as well as a retentate, containing most of the MCR and metals, the retentate is then subjected to hydroconversion at elevated temperature in the presence of hydrogen at a hydrogen pressure not higher than 500 psig (3500 kPag) using a dispersed metal-on-carbon catalyst to produce a hydroconverted effluent which is fractionated to give naphtha, distillate and gas oil fractions. The permeate from the membrane separation may be used as FCC feed either as such or with moderate hydrotreatment to remove residual heteroatoms. The process has the advantage that the hydroconversion may be carried out in low pressure equipment with a low hydrogen consumption as saturation of aromatics is reduced.

Abstract: A heavy residual petroleum feed boiling above 650° F.+ (345° C.+) is subjected to hydroconversion at elevated temperature in the presence of hydrogen at a hydrogen pressure not normally higher than 500 psig (3500 kPag) using a dispersed metal-on-carbon catalyst to produce a hydroconverted effluent which is fractionated to form a low boiling fraction and a relatively higher boiling fraction which is subjected to membrane separation to produce a permeate which is low in metals and Microcarbon Residue (MCR) as well as a retentate, containing most of the MCR and metals. The process has the advantage that the hydroconversion may be carried out in low pressure equipment with a low hydrogen consumption as saturation of aromatics is reduced.

Abstract: A delayed coking process for making substantially free-flowing shot coke. A coker feedstock, such as a vacuum residuum, is treated with an additive, such as a elemental sulfur, high surface area substantially metals-free solids, process fines, a mineral acid anhydride and the like. The treated feedstock is then heated to coking temperatures and passed to a coker drum for a time sufficient to allow volatiles to evolve and to produce a substantially free-flowing shot coke.
