Definitions

  • This invention relates to a process for the treatment of heavy petroleum oil resid streams. More particularly, this invention relates to a process for the treatment of heavy petroleum oil resid streams to obtain therefrom useful oil fractions substantially free of asphaltenes and heavy metals.
  • thermal cracking processes include the visbreaking process, such as exemplified by U. S. 4,454,023, and the delayed coking process both of which have been extensively practiced for effecting the thermal cracking of heavy petroleum oil.
  • Solvent extraction processes also have been proposed. However, the use of such processes by themselves alone provide for the recovery of only a limited amount of useful oil products. This is especially true when the feedstock contains a very high content of heavy metals. From the viewpoint of effectively utilizing both resources and energy, it is clear that further improvements in the treatment of heavy petroleum oils resids are needed.
  • the present invention relates to a novel and improved process for treating heavy petroleum oil resid feed streams.
  • the novel and improved process of the present invention comprises introducing a heavy petroleum oil feed stream, which has been preheated to a temperature in the range of from 450°C to 550°C in a preheater, into an upper portion of an adiabatic thermal cracker.
  • the preheated heavy petroleum oil feed stream is caused to flow downwardly through the thermal cracker in a plug-flow condition through the use of multi-stage horizontally positioned perforated plates which are spaced at intervals throughout the thermal cracker.
  • the operating conditions employed within the thermal cracker include temperatures in the range of from 390°C to 450°C, pressures of at least atmospheric pressure and residence times in the range of from 1 to 5 hours.
  • distillate vapors and gaseous products resulting from the thermal cracking of the heavy petroleum oil resid feed stream are removed by means of steam introduced into a lower portion of the thermal cracker, which steam flows upwardly in a countercurrent direction to the descending heavy petroleum oil resid feed stream undergoing thermal cracking.
  • steam introduced into a lower portion of the thermal cracker, which steam flows upwardly in a countercurrent direction to the descending heavy petroleum oil resid feed stream undergoing thermal cracking.
  • From 30 to 65 percent of the components in the heavy petroleum oil resid feed stream having boiling points above 500°C convert to components having boiling points below 500°C.
  • From the lower portion of the thermal cracker there is withdrawn a cracked resid bottoms stream, which resembles a liquid pitch.
  • This bottoms stream which contains an asphaltene fraction, heavy metals and useful oil components, then is mixed with a solvent and the mixture subjected to solvent extraction.
  • the solvent extraction is carried out at temperatures and pressures at or near the critical point of the solvent and above the softening point of the asphaltene fraction. Under such conditions a mixture of the asphaltene fraction and heavy metals is rapidly and efficiently separated from the useful oil components in said bottom stream.
  • the single Figure is a schematic flow diagram illustrating one embodiment of the process of the present invention.
  • the novel process of the present invention is comprised of a series of steps, whereby the overall yield and quality of useful oil components therefrom are improved.
  • the steps comprise subjecting a heavy petroleum oil resid feed stream, such as an atmospheric or vacuum distillation column bottom resid (i.e., an atmospheric or vacuum residue) to selective thermal cracking.
  • the selective thermal cracking is carried out under conditions whereby cracking of the heavy petroleum oil resid feed stream is confined to the decomposition of only those high molecular hydrocarbon constituents or components in the feedstock that are relatively easily decomposed.
  • This selective thermal cracking step separation and recovery of the light hydrocarbons formed is accelerated by simultaneous steam stripping.
  • Thermally-cracked heavy petroleum oil resid withdrawn from the bottom of the thermal cracker then is subjected to a highly efficient critical solvent extraction-separation treatment which comprises the second step of the process of the present invention. Through the use of this critical solvent extraction-separation step, substantially all of any remaining useful oil components remaining in the thermally-cracked heavy oil resid are recovered.
  • the operating conditions employed in both the thermal cracking step and the critical solvent extraction-separation step are selected in accordance with the composition of the heavy petroleum oil resid feed stream such that the total yield of useful oil components recovered as well as the quality thereof is maximized.
  • said yield and quality are much higher than can be obtained from more conventional processes such as the catalytic cracking, hydrocracking, visbreaking, delayed coking or solvent extraction processes.
  • the resid or bottom stream recovered from the thermal cracking step of the present process is in a highly fluid state as is the heavy metals containing asphaltene fraction recovered in the solvent extraction-separation step. The highly fluid nature of these materials makes them more easily handled than those recovered from the more conventional processes mentioned above.
  • the operating conditions employed in the thermal cracking will be conditions which promote the selective concentration of nickel, vanadium and other heavy metals present in the heavy petroleum oil resid feedstock into the asphaltene fraction of the thermally-cracked heavy oil resid stream withdrawn from the bottom of the thermal cracker.
  • the degree of cracking carried out in the thermal cracking step of the process of the present invention is restricted such that not more than 65 percent by weight, and preferably not more than 60 percent by weight of the components in the heavy petroleum oil resid feed having atmospheric boiling points above 500°C are decomposed to components having atmospheric boiling points below 500°C.
  • the separation, recovery, transportation and the like, of the final resid or asphaltene fraction becomes extremely difficult requiring complex apparatus to accomplish these tasks.
  • the degree of thermal cracking carried out in the first step of the process of the present invention is limited such that the thermally-cracked heavy oil residue recovered therefrom contains minimal amounts of coke.
  • the final resid or asphaltene fraction extracted therefrom in the extraction step of the present invention will be in a highly fluid state at process temperatures. Such highly fluid state facilitates its separation, recovery and the like and simplifies the type of equipment employed and the arrangement thereof. Further teachings relating to the operating conditions, equipment and the like for carrying out this selective thermal cracking or first step in the process of the present invention can be found in U.S. Patent Nos. 4,435,276 and 4,443,328.
  • the thermally-cracked heavy oil resid or bottoms stream withdrawn from the thermal cracker is subjected to a critical solvent extraction-separation which comprises the second step of the present invention.
  • the thermally-cracked heavy oil resid is mixed with a critical solvent.
  • This mixture then is subjected to temperatures higher than the softening point of the asphaltene fraction in the thermally-cracked resid and preferably to conditions of temperature and pressure within the proximity of the critical point of the solvent. Under these conditions, the asphaltene fraction is less soluble in the critical solvent than the useful oil components and a rapid separation of the asphaltene fraction from the mixture can be effected.
  • a heavy petroleum oil resid feedstock such as an atmospheric or vacuum distillation bottoms resid
  • conduit 1 a heavy petroleum oil resid feedstock
  • preheater 2 the heavy petroleum oil resid feedstock is heated to temperatures in the range of from 450°C to 550°C under pressures in the range of from 98 kPa to 980 kPa (1 to 10 kg/cm2).
  • preheater 2 In order to avoid coking of the feedstock it is passed through preheater 2 at a velocity in the range of from 2 to 20 m/s.
  • the preheated feedstock then is conveyed from preheater 2 through conduit 3 to an upper portion of upright cylindrical thermal cracker 4.
  • Steam, and preferably superheated steam is introduced into a bottom portion of thermal cracker 4 through conduit 18 and steam distributing means 18'.
  • This superheated steam flows upwardly and countercurrent to the downwardly flowing feedstock which is undergoing thermal reaction.
  • the countercurrently flowing superheated steam facilitates the evaporation and removal of cracker light oil components from the downwardly flowing thermally reacting feedstock, thus eliminating the need of subjecting the thermally-cracked resid recovered from thermal cracker 4 to vacuum distillation.
  • the amount of superheated steam introduced to thermal cracker 4 through conduit 18 and distributing means 18' to evaporate and remove cracked light oil components will be in the range of from 5 percent to 20 percent by weight of the feedstock stream undergoing thermal reaction in thermal cracker 4.
  • thermal cracker 4 is operated at atmospheric pressure and at temperatures ranging from 390°C to the temperature of the preheated feedstock introduced thereto.
  • the residence time of the feedstock in thermal cracker 4 will be at least two times that for a visbreaking process or from 1 to 10 hours.
  • the thermally reacting feedstock be made to descend downwardly through thermal cracker 4 in a substantially plug-flow manner and that it not be allowed to stagnate at or near the internal surfaces of thermal cracker 4. Failure to maintain plug-flow also can result in the formation of channels and vortexes in the descending column of thermally reacting feedstock. Such channels and vortexes, once formed, provide paths along which portions of the feedstock can quickly pass through, and out of, thermal cracker 4. The shorter residence time for these portions of the thermally reacting feedstock in thermal cracker 4 can lead to an undesirable lowering of the overall conversion of the feedstock to the more desirable useful oil products.
  • thermal cracker 4 is equipped with multiple horizontal perforated partition plates 4a through 4j.
  • Thermal cracker 4 also is equipped with a drive shaft 38 driven by motor 40.
  • Drive shaft 38 is fitted with multiple horizontal scraper blades, two of which (38a and 38b) are designated on the Figure.
  • the horizontal scraper blades attached to drive shaft 38 are located immediately adjacent to each of the multiple horizontal perforated partition plates 4a through 4h and extend outwardly from drive shaft 38 to near the internal surface of thermal cracker 4.
  • the purpose of drive shaft 38 and the multiple horizontal scraper blades affixed thereto is to provide for the even distribution throughout the downwardly flowing thermally reacting feedstock of the meso-phase coke precursors produced as part of the thermal cracking reaction. By maintaining these meso-phase coke precursors evenly distributed throughout the descending reactions stream, agglomeration of these precursors and, therefore, the accumulation of coke within thermal cracker 4 substantially is prevented.
  • This mixture then is discharged from the upper portion of thermal cracker 4, through conduit 19 and condenser 20 to separator 21.
  • separator 21 the mixture is separated into a cracked gas stream, a condensed water stream and a cracked light oil stream which are removed from separator 21 through conduits 22, 23 and 34, respectively.

  • the first fluid light phase is withdrawn from the top of first separating column 9 via communicating conduit 10 and conveyed to second separating column 11 through heater 27. By means of heater 27, the first fluid light phase further is heated to a temperature greater than the temperature employed in first separating column 9.
  • the fluid-like first heavy phase which comprises asphaltenes, heavy metals and some solvent is withdrawn from the bottom portion of first separating column 9 via conduit 12, containing pressure reducing valve 35, and introduced into separator 24. In separator 24 the pressure further is reduced to thereby effect vaporization of the solvent.
  • the solvent is recovered from separator 24 through conduit 26. This recovered solvent then can be returned to mixer 7 through communicating condenser 30, pump 32, and conduit 33.
  • the asphaltenes, upon vaporization and removal of the solvent in separator 24, are removed and recovered therefrom in a highly fluid state through conduit 25.
  • the first light phase is withdrawn from first separating column 9 and conveyed into second separating column 11 after being heated in heater 27 to a temperature higher than the temperature employed in first separating column 9.
  • the first light phase separates into a second fluid light phase comprising the useful oil components and solvent, and a fluid-like second heavy phase comprising the resinous components and some solvent.

  • the fluid-like second heavy phase comprising the resinous components is discharged in a fluid state from the bottom of second separating column 11 through conduit 15 for recovery, or for recycle to preheater 2 for mixing with fresh feedstock and further cracking in thermal cracker 4.
  • third separating column 14 wherein the solvent is in a supercritical state the second light phase undergoes separation into a third light phase and a fluid-like third heavy phase comprising the desired product, i.e., a deasphalted oil.
  • This product is withdrawn from the bottom of third separating column 14 through conduit 16 and recovered.
  • the third light phase comprising the bulk of the original extraction solvent is withdrawn from the top of third separating column 14 through conduit 17 and recycled via communicating cooler 29 and pump 31 back to mixer 7.
  • Make-up solvent can be supplied to mixer 7 by means of pump 36 through conduit 37 to replenish solvent lost in small amounts from the system in company with the asphaltenes, resins and useful oil components being separated and recovered in this portion of the process of the present invention.
