Enhanced solvent deasphalting process for heavy hydrocarbon feedstocks utilizing solid adsorbent
ActiveUS7566394B2Improve performanceImprove current efficiencyWorking-up pitch/asphalt/bitumen by selective extractionHydrocarbon distillationBenzeneActivated carbon
A solvent deasphalting of crude oil or petroleum heavy fractions and residues is carried out in the presence of a solid adsorbent, such as clay, silica, alumina and activated carbon, which adsorbs the contaminants and permits the solvent and oil fraction to be removed as a separate stream from which the solvent is recovered for recycling; the adsorbent with contaminants and the asphalt bottoms is mixed with aromatic and / or polar solvents to desorb the contaminants and washed as necessary, e.g., with benzene, toluene, xylenes and tetrahydrofuran, to clean adsorbant which is recovered and recycled; the solvent-asphalt mixture is sent to a fractionator for recovery and recycling of the aromatic or polar solvent. The bottoms from the fractionator include the concentrated PNA and contaminants and are further processes as appropriate.

Apparatus for dehydrating oil
InactiveUS6224716B1Distillation regulation/controlEvaporation with vapour compressionVacuum pressureClosed loop
A system for dehydrating lubricating and hydraulic fluids includes a heating circuit and circuitry for creating a vacuum. The heating circuitry introduces a stream of heated fluid into a vacuum chamber in which a partial vacuum is drawn by the vacuum circuit. Aqueous components of the fluid stream are flashed in the vacuum chamber by virtue of the elevated temperature and reduced pressure. Dehydrated fluid is then collected and evacuated from the vacuum chamber. Vapor from the vacuum chamber, including the aqueous components of the fluid stream are collected, condensed and separately evacuated. The heating circuit limits surface temperature of a heating element in a closed-loop manner to avoid degradation of the fluid. The fluid stream is introduced into the vacuum chamber or is recirculated through the heating circuit to maintain a desired level of fluid temperature in a closed-loop manner. The system includes circuits for evacuating dehydrated fluid in a closed-loop manner and for automatically discharging condensate. The technique avoids undesirable foaming of dehydrated fluid within the vacuum chamber. A vacuum pulsing circuit is provided for periodically pulsing vacuum pressure within the vacuum chamber to aid in flashing aqueous components from the heated fluid stream.

Described herein are methods and mechanisms for laterally dispensing fluid to a coke drum in a predictable and maintainable manner that alleviates thermal stress. In one embodiment, the methods and mechanisms utilize a split piping system to dispense fluid through two or more inlets into a spool that is connected to a coke drum and a coke drum bottom deheader valve. A combination of block valves and clean out ports provides a more effective means to clean the lines and allows fluid to be laterally dispensed in a controllable and predictable manner. The fluid is preferably introduced to the spool in opposing directions toward a central vertical axis of the spool at equal but opposing angles ranging from minus thirty (−30) to thirty (30) degrees relative to a horizontal line laterally bisecting the spool. Alternatively, however, fluid can be introduced to the spool tangentially.

A process for upgrading hydrocarbonaceous oil containing heteroatom-containing compounds where the hydrocarbonaceous oil is contacted with a solvent system that is a mixture of a major portion of a polar solvent having a dipole moment greater than about 1 debye and a minor portion of water to selectively separate the constituents of the carbonaceous oil into a heteroatom-depleted raffinate fraction and heteroatom-enriched extract fraction. The polar solvent and the water-in-solvent system are formulated at a ratio where the water is an antisolvent in an amount to inhibit solubility of heteroatom-containing compounds and the polar solvent in the raffinate, and to inhibit solubility of non-heteroatom-containing compounds in the extract. The ratio of the hydrocarbonaceous oil to the solvent system is such that a coefficient of separation is at least 50%. The coefficient of separation is the mole percent of heteroatom-containing compounds from the carbonaceous oil that are recovered in the extract fraction minus the mole percent of non-heteroatom-containing compounds from the carbonaceous oil that are recovered in the extract fraction. The solvent-free extract and the raffinate concentrates may be used directly or processed to make valuable petroleum, chemical or industrial products.

InactiveUS6645350B1Thermal non-catalytic crackingHydrocarbon distillationShortest distanceFractionation
Problems generated by heat transfer through the vertical dividing wall of a trayed "dividing wall column" and into a downcomer of a tray are mitigated by providing a separate vertical isolation wall between the downcomer and dividing wall. The isolation wall forms one side of the downcomer and is spaced a short distance outward from the dividing wall to form an isolation volume which thermally insulates the downcomer from the dividing wall. The added wall is parallel to the dividing wall and supplants the dividing wall as a part of the downcomer. It eliminates a need to insulate the dividing wall.

An acoustic / pressure wave-driven device for separating a first component from a mixture of the first component and a second fluid component. The device comprises a rich reservoir, a lean reservoir, a pump reservoir, a bridge structure, and an acoustic / pressure wave source. The rich reservoir is for containing a fluid mixture having an elevated concentration of the first component. The lean reservoir is for containing a fluid mixture having a lesser concentration of the first component that is leaner than the concentration of the first component in fluid mixture of the rich reservoir. The pump reservoir contains a fluid mixture of the first component and the second fluid component. The bridge structure has a sidewall defining a gradient channel in fluid communication with the rich reservoir and the lean reservoir and a length extending there between. The gradient channel is for containing a fluid having a concentration gradient of the first component along its length. A diffusion portion of the sidewall disposed between the gradient channel and the pump reservoir is adapted to permit diffusion of at least the first component between the gradient channel and the pump reservoir while preventing fluid flow there between. The acoustic / pressure wave source provides acoustic waves into the pump reservoir to cause pressure oscillations in the fluid mixture therein adjacent to the diffusion portion to move molecules of the target component against the concentration gradient from the lean reservoir into the rich reservoir.

Process of hydrotreating heavy hydrocarbon oil
ActiveUS7651605B2Increase deactivation rateImprove throughputCoke ovensHydrocarbon distillationReaction temperatureHeavy crude oil
When a heavy fuel oil with a sulfur content of 1 percent by mass or lower is produced from a feedstock consisting of a heavy hydrocarbon oil derived from a heavy crude oil having an API degree of 30 or less and containing sulfur and metal components in amounts larger than those of ordinary crude oil, the conventional processes requires higher reaction temperature and was accompanied with a remarkably enhanced deactivation rate of the catalyst which results in a remarkable shortened lifetime thereof. Therefore, it is regarded as substantially impossible to treat the feedstock. However, the present invention makes it possible to produce a low sulfur heavy fuel oil with a sulfur content of 1 percent by mass or less by hydrotreating a mix oil of 100 parts by volume of a heavy hydrocarbon oil derived from a heavy crude oil with an API degree of 30 or less and 30 to 1000 parts by volume of a heavy hydrocarbon oil derived from a light crude oil with an API degree of 35 or greater, without lowering the degree of demetallization while retarding the deactivation rate of the catalyst.
