A supercritical water separation process and system is disclosed for the removal of metals, minerals, particulate, asphaltenes, and resins from a contaminated organic material. The present invention takes advantage of the physical and chemical properties of supercritical water to effect the desired separation of contaminants from organic materials and permit scale-up. At a temperature and pressure above the critical point of water (374° C., 22.1 MPa), nonpolar organic compounds become miscible in supercritical water (SCW) and polar compounds and asphaltenes become immiscible. The process and system disclosed continuously separates immiscible contaminants and solids from the supercritical water and clean oil product solution. The present invention creates a density gradient that enables over 95% recovery of clean oil and over 99% reduction of contaminants such as asphaltenes and particulate matter depending on the properties of the contaminated organic material.

The subject invention provides microbe-based products, as well as their use to improve oil well production and increase the value of heavy crude oil. Specifically, the subject invention provides cultivated yeast products, which can be applied to oil and/or oil and gas production equipment to improve production and increase the economic value of heavy crude oil by, for example, upgrading heavy oils and/or converting heavy hydrocarbon substances, such as asphalts, asphaltenes, tars, bitumens and/or petcokes into lighter hydrocarbon substances.

The present invention relates to a process for preparing an asphaltene-stabilized fuel oil comprising (i) mixing an asphaltene-containing oil fraction(s) and a high-saturated hydrocarbon oil fraction(s) to obtain a mixture of oil fractions; and (ii) filtering the obtained mixture through a filtering medium, and the asphaltene-stabilized fuel oil obtained therefrom.

A method for stabilizing asphaltenes in petroleum feedstocks such as crude oil includes adding to the feedstock an effective amount of an additive containing at least one waste plastic. Suitable waste plastics include, but are not necessarily limited to, polyethylene, polyethylene terephthalate, polystyrene, polycarbonate, polyamide, and polyurethane, and combinations thereof. By “stabilizing” is meant keeping the asphaltenes in solution in the petroleum feedstocks.

A process for producing olefins from the hydrocarbon feed includes introducing the hydrocarbon feed into a Solvent Deasphalting Unit (SDA) to remove asphaltene from the hydrocarbon feed producing a deasphalted oil stream, wherein the SDA comprises a solvent that reacts with the hydrocarbon feed, and the deasphalted oil stream comprises from 0.01 weight percent (wt. %) to 18 wt. % asphaltenes; introducing the deasphalted oil stream into a steam catalytic cracking system; steam catalytically cracking the deasphalted oil stream in the steam catalytic cracking system in the presence of steam and a nano zeolite cracking catalyst to produce a steam catalytic cracking effluent; and separating the olefins from the steam catalytic cracking effluent.

The invention concerns a process for converting a hydrocarbon feed, said process comprising the following steps: a) a step of hydrocracking the feed in the presence of hydrogen; b) a step of separating the effluent obtained from step a); c) a step of precipitating sediments, in which the heavy fraction obtained from the separation step b) is brought into contact with a distillate cut at least 20% by weight of which has a boiling point of 100° C. or more for a period of less than 500 minutes, at a temperature in the range 25° C. to 350° C., and at a pressure of less than 20 MPa; d) a step of physical separation of the sediments from the heavy fraction obtained from step c); e) a step of recovering a heavy fraction having a sediment content, measured using the ISO 10307-2 method, of 0.1% by weight or less.

Processes herein may be used to thermally crack various hydrocarbon feeds, and may eliminate the refinery altogether while making the crude to chemicals process very flexible in terms of crude. In embodiments herein, crude is progressively separated into at least light and heavy fractions. Depending on the quality of the light and heavy fractions, these are routed to one of three upgrading operations, including a fixed bed hydroconversion unit, a fluidized catalytic conversion unit, or a residue hydrocracking unit that may utilize an ebullated bed reactor. Products from the upgrading operations may be used as feed to a steam cracker.
