Process scheme configurations are disclosed that enable conversion of crude oil feeds with several processing units in an integrated manner into petrochemicals. The designs utilize minimum capital expenditures to prepare suitable feedstocks for the steam cracker complex. The integrated process for converting crude oil to petrochemical products including olefins and aromatics, and fuel products, includes mixed feed steam cracking and fluid catalytic cracking. Feeds to the mixed feed steam cracker include light products and naphtha from hydroprocessing zones within the battery limits, recycle streams from the C3 and C4 olefins recovery steps, and raffinate from a pyrolysis gasoline and FCC naphtha aromatics extraction zone within the battery limits.
摘要:
A method for reducing sulfur and lowering viscosity in bunker oil by the steps of passing bunker oil over a core that ionizes the bunker oil with an electrostatic charge. The core consists of a metal bar being made of an alloy comprising, by weight, 40-70% copper, 10-32% nickel, 15-40% zinc, 2-20% tin and 0.05-10% silver. The metal bar of the core comprises a plurality of grooves, which allows the bunker oil to be agitated as it comes in contact with the core, activating an electrostatic charge. The electrostatic charge of the core creates a magnetic catalytic reaction that causes: (1) a molecular separation in molecular chains within the bunker oil thereby lowering the viscosity of the bunker oil and (2) sulfur to merge with metals and create metal sulfides in the bunker oil thereby reducing the sulfur in the bunker oil.
摘要:
A method of producing heavy oil by first injecting water and sulfur hexafluoride molecules into a region. The method then introduces electromagnetic waves such as microwaves and/or radio frequencies into the region at a frequency sufficient to excite the water and the sulfur hexafluoride molecules and increase the temperature of at least a portion of the water and sulfur hexafluoride molecules within the region to produce heated water and sulfur hexafluoride molecules. At least a portion of the heavy oil is heated in the region by contact with the heated water and sulfur hexafluoride molecules to produce heated heavy oil. The heated heavy oil is then produced.

摘要:
The subject process enhances catalytic activity for demetallization and desulfurization of a residue feed stream by splitting a recycle hydrogen stream and feeding each of the split hydrogen streams to the first and second stages of demetallation and desulfurization, respectively, with interstage separation. The recycle hydrogen stream may first undergo scrubbing to remove acid gases and compression before recycle. The recycle hydrogen stream is taken from a first hot vapor stream from the first hydrotreating unit and a second hot vapor stream from the second hydrotreating unit.

Composition for solubilization of organic residues of raw materials of fossil origin including a mixture of fatty acid esters of formula R1COOR2 in which R1 represents a linear or branched C5 to C23 carbon-based chain, optionally including one or more unsaturations, R2 represents a linear or branched C1 to C10 carbon-based chain, optionally including one or more unsaturations; the composition includes: a) at least 18% by weight of C6 to C10 fatty acid esters, b) at least 18% by weight of C18 to C24, in particular C18 to C22 fatty acid esters, including at least one double bond. The invention also relates to the use of the compositions.
摘要:
A process for recovering hydrocarbons from a slurry hydrocracking reactor. The hydrocarbons are recovered by taking a drag stream of the slurry in the reactor. After separating lighter hydrocarbons in a separation zone, the heavier hydrocarbons can be processed in a deashing zone, with a vacuum column bottoms from a separation of the effluent stream recovered from the reactor. The deashing zone can recover the heavier hydrocarbons in a deashed pitch. Additionally, a VGO rich stream from the deashing zone may be recycled back to the reactor.
摘要:
Methods are provided for making asphalt from crude oils derived from mined oil sands that have been subjected to a solvent froth treatment as part of the process for making a crude oil that is suitable for pipeline transport. A froth treatment is used that preserves a greater percentage of the asphaltene content of the crude oil derived from the mined oil sands.
摘要:
A modular crude oil refinery (MCOR) is designed for smaller scale deployment with a capacity to process in the range of 3,000-4,000 barrels of crude oil per day in a single production unit and with the potential to scale to over 100,000 barrels per day with linked production units. More specifically, a MCOR includes a low temperature, low pressure primary separation reactor, condensing system and recirculation systems operating in a closed loop configuration that enable the production of both heavy and light hydrocarbon products with substantially no emissions. The MCOR has the capability to receive and process crude-oil feedstocks of varying API gravity and be controlled to produce a variety of both heavy and light products including cleaner-burning bunker fuels, jet fuels, diesel fuels, gasoline fuels and asphalt binders.
