  • Publication number: 20180208860
    Abstract: In a hydrocracking process, the hydrocarbon feed is processed by a guard reactor operating at maximum severity temperatures. The processing in the guard reactor maximizes the removal of metals and performs hydroenitrogenation steps and hydrodesulfurization steps. The demetallized and partially desulfurized and denitrogenized hydrocarbon feed is then sent to a treating reactor for further hydrodenitrogenization and hydrodesulfurization before being sent further down stream for further hydrocracking processing.

  • Patent number: 9580662
    Abstract: The present invention relates to quenching, during hydroprocessing of a hydrocarbon feed stream. More particularly, the present invention provides for quenching in hydroprocessing of a hydrocarbon feed stream through a hydroprocessing vessel. Liquid quenches (from high pressure hot separator) were installed to assist in cooling the reactor inter-bed, and to maintain good liquid irrigation of the catalyst. The soluble hydrogen in the stream, kinetically active and available for immediate reaction, is the final piece of the puzzle for why this unit runs so well.

  • Patent number: 8080426
    Abstract: This unique process is a feed forward control of hydroprocessing by on-line sulfur speciation. An on-line gas analyzer such as (GC) with a sulfur specific detector (AED) would be installed to analyze the feed to a hydrotreating unit. The analyzer would be calibrated to quantify the individual sulfur compounds or classes of sulfur compounds present in the feed. The output from the analyzer would be linked to the unit's distributed control system to automatically change temperatures and feed rates to change hydrotreating severity. This invention could bring economical benefits by increasing the life of the hydrotreating catalyst, reducing operating cost, and decreasing the potential amount of offspec product. In one embodiment, the hydrotreating is a hydrodesulphurization process.

  • Patent number: 6402938
    Abstract: Used Motor Oil is re-refined by direct injection of a superheated, non-hydrogenating recycle vapor. The process operates at low pressures, preferably from atmospheric—10 atmospheres absolute. Preferably a significant amount of the energy required to vapor used motor oil is supplied in the form of increased sensible heat of a recycle vapor stream. Direct injection of superheated vapor reduces or eliminates fouling which can occur when indirect heat exchange is used to supply the heat needed to vaporize used motor oil.

  • Patent number: 6099721
    Abstract: A process for use of magnetic separation to remove non-magnetic particles from FCC catalyst is disclosed. A stream of circulating catalyst from a fluidized catalytic cracking (FCC) unit is charged to a magnetic separator. The catalyst is magnetically fractionated into at least three fractions, a high-metals fraction which is discarded, an intermediate-metals content fraction which is directly recycled to the FCC unit, and an inert, relatively magnetic metals-free fraction which is also discarded. Preferably, the high-metals fraction is immediately mixed with the inert, low-metals fraction, and the combined high-metals/inert fraction is pneumatically transmitted together to a spent catalyst storage facility for disposal.

  • Patent number: 5985134
    Abstract: A startup method for a fluidized catalytic cracking (FCC) unit operating with a magnetic catalyst separation means is disclosed. Magnetic strength, or separation severity, is maintained or increased until most of the catalyst has passed through the magnetic separation unit. After this point, magnetic flux and/or centrifugal forces, are decreased for lined-out operation. Preferably a MagnaCat.RTM. catalyst separation unit is used for magnetic fractionation of catalyst.

  • Patent number: 5985133
    Abstract: Circulating equilibrium catalyst (ECAT) in a fluidized catalytic cracking (FCC) is gently attrited in an internal or closely coupled attriter to produce fines and attrited catalyst which is recycled to the FCC unit for fines removal. Average particle size of the circulating ECAT is slightly reduced coupled with some fines formation, improving fluidization. Some metals removal is possible as metals tend to accumulate on the surface of the ECAT. The existing fines removal equipment in the FCC is used to remove produced fines, though operating conditions may be altered to reduce particulates emissions during periods of catalyst attrition. A dual orifice plate attriter closely coupled with and discharging into the FCC regenerator is preferred, but a high velocity gas jet within the FCC regenerator may also be used. The process operates without a magnetic catalyst separation unit.

  • Patent number: 5972208
    Abstract: A process and apparatus for incorporating additives into a circulating inventory of equilibrium catalyst in a fluid catalyst cracking (FCC) unit are disclosed. Hot regenerated catalyst is removed from the FCC regenerator, cooled, optionally subjected to magnetic catalyst separation, and at least a portion of the cooled catalyst is contacted with a solution of an additive material without forming a separated liquid phase. Additive treated catalyst is recycled to the FCC unit, preferably directly into the regenerator.

  • Patent number: 5958219
    Abstract: A process for metals passivation of metals-contaminated equilibrium catalyst (ECat) used in a fluidized catalytic cracking (FCC) process is disclosed. Repeated treatment of a slip stream of ECat in a high-strength magnetic field, preferably a magnetic catalyst separator, changes the properties of the ECat, promoting growth of relatively large crystals or deposits of metal deposits on ECat which are less catalytically poisonous. Magnetic conditioning permits an increase in metals levels on ECat from, e.g., 3000 to 4000 ppm, without increasing hydrogen and/or coke make. Metals passivation by magnetic conditioning can also be used to concentrate feed metals on the oldest catalyst in the unit. This allows magnetic separation of the oldest catalyst in the unit after 1-6 months of magnetic conditioning, even though feed metals levels are otherwise insufficient to permit effective magnetic catalyst separation.

  • Patent number: 5746321
    Abstract: Optimized utilization of combinations of fluid catalyst magnetic separator, classifier, and/or attriter can be used to achieve lower catalyst cost, and better catalyst activity and selectivity through control of metal-on-catalyst, particle size and particle size distribution. This process is especially useful when processing high metal-containing feedstocks. This provides a catalyst recovery unit (RCU.TM.) ancillary to an FCC or similar unit.

  • Patent number: 5728291
    Abstract: In this combination process, solvent deasphalting (SDA) concentrates metals in the bottoms product which can be blended to asphalt as a product or for sending to the Calderon or similar process and outputs a high carbon (4+ concarbon) feed which is readily cracked to valuable transportation fuels by an RCC.RTM. cracking unit (or a conventional FCC with catalyst cooler and oxygen to the regenerator so that it acts as an RCC). The Rose process can be used instead of SDA to save utilities. By this invention, heavy crude can be converted to valuable transportation fuels and asphalt product, and catalyst make-up can be sharply reduced in the RCC or FCC unit because metals (asphaltenes and porphyrins) are removed before cracking. Novel asphalt compositions and blending are also disclosed. Asphalt from the SDA can preferably be blended with lube plant extract (or other aromatic extract) to produce specific asphalts meeting new SHRP specifications for paving.
