A subsea fluids storage facility comprises a tank for holding and separating fluids which is equipped with ballast capacity and a separable base to be deployed upon the seabed in shallow or deep water, and the storage facility is connectable to a surface production facility, especially a buoy for processing fluids. In deep water the tank is held at a depth above the base for temperature controlled stabilization of produced oil in the tank.

An NMR-based system (10) to analyze one or more of the following: (i) crude oil property, (ii) crude oil rheology of crude oil, comprising an NMR device (11) for providing time and/or batch resolved NMR analysis and/or crude oil rheological profile, said NMR having a crude oil inflow pipe (13), and is in a fluid connection (14) with a crude oil refinery facility (12); wherein said system further comprising a computer readable medium configured to store a retrievable crude oil NMR analysis and/or crude oil rheological profile of a desired crude oil product (standard crude oil product, SCOP), thereby providing said system means to compare NMR analysis and/or crude oil theological profile of said SCOP with said time or batch resolved crude oil.

A method of treating a contaminated oil comprising preparing a brine solution, adding ozone to the brine solution to produce ozonated brine solution, adding a volume of ozonated brine solution to a volume of the contaminated oil, mixing the volumes of contaminated oil and ozonated brine solution with coagulant and surfactant at a shear rate sufficiently high so as to cause formation of an emulsion of the contaminated oil and the brine solution, stopping the mixing, thereby causing the emulsion to separate into an aqueous brine liquid phase and an oil liquid phase, separating the brine liquid phase from the oil liquid phase, and separating at least one contaminant from the oil liquid phase to produce a volume of purified oil.

The present invention relates to a process and system for complete conversion of crude oils by integrating Desalter unit, Atmospheric and vacuum column, high severity FCC process, Naphtha cracking process, residue slurry hydrocracking process, Delayed coking process, Selective mild hydrocracking aromatic production unit, Dehydrogenation units, Aromatic/olefin recovery section, gasifier unit along with syngas to olefins conversion section.

The invention generally relate to processes, systems, and methods for the pyrolysis of hydrocarbon feeds containing one or more forms of mercury, e.g., the steam cracking of heavy oil, such as crude oil. Effluent from the pyrolysis is processed to remove various forms of mercury produced during the pyrolysis and/or carried over from the hydrocarbon feed.

A method for the treatment of heavy crude oil with magnetized oxygen/air micro nano bubble water, comprising the steps of generating micro nano bubbles water from treated water by a depressurization process; pumping heavy crude oil and oxygen with the micro nano bubbles water at an injection port; injecting via the injection port a mixture of heavy crude oil and oxygen micro nano bubbles water into a first magnetic unit; subjecting the mixture to a magnetic field under static mixing conditions in the first magnetic unit; injecting the mixture into an interim tank; pressurizing the heavy crude oil and water exiting the interim tank via a slurry pump; pumping the heavy crude oil and water through a second magnetic unit before routing to a first hydrocyclone unit; and routing an overflow of the heavy crude oil for refinery purposes.

The subject invention provides microbe-based products, as well as their use to improve oil production and refining efficiency by, for example, remediating the disposable layers in oil tanks and other oil storage units. In preferred embodiments, the microbe-based products comprise biochemical-producing yeast and growth by-products thereof, such as, e.g., biosurfactants. The subject invention can be used to remediate rag layer and/or other dissolved solid layers that form in water-oil emulsions. Furthermore, the subject invention can be used for remediating solid impurities, such as sand, scale, rust and clay, in produced water, flow-back, brine, and/or fracking fluids.

A process for producing light olefins comprising thermal cracking. Hydrocracked streams are thermally cracked in a steam cracker to produce light olefins. A pyrolysis gas stream is separated into a light stream and a heavy stream. A light stream is separated into an aromatic naphtha stream and a non-aromatic naphtha stream. The aromatics can be saturated and thermally cracked. The integrated process may be employed to obtain olefin products of high value from a crude stream.

A method of recycling gaseous hydrocarbons includes flowing a hydrocarbon gas composition from a secondary separator into a compressor unit to form a compressed mixture. The secondary separator includes a crude liquid hydrocarbon input stream from a primary separator. The method includes flowing the compressed mixture into a cooling unit to cool the compressed mixture, to form a cooled composition comprising liquid hydrocarbons. The method includes flowing the liquid hydrocarbons from the cooled composition into the primary separator.
