Definitions

  • the invention relates to a method for obtaining evaporable oils from the residue of the hydrogenation of heavy or heavy oils, bitumen, tar, oils from oil shale or tar sand and the like by vacuum distillation.
  • the oils obtained by vacuum distillation can be hydrated to higher quality products under relatively mild conditions.
  • the process engineering of vacuum distillation of such hydrogenation residues is known, but the handling of the vacuum residue poses considerable problems. In particular, the discharge from the vacuum column and the transport for further processing are extremely difficult due to the high viscosity of the vacuum residue.
  • the object of the present invention is to overcome these difficulties. According to the invention, this occurs in that the hydrogenation residue is fed from below into the liquid space of a single- or multi-shaft screw machine (7) via a positive-displacement pump system (5), which has a vaporization zone (8) and a smoldering zone (9) separated by a mechanical compression stage (16) ), occurs and is subjected to distillation under reduced pressure and subsequent smoldering.
  • the hydrogenation residue which constantly increases its viscosity during the distillation, is continuously circulated by the screw and is thereby passed through the distillation zone of the screw machine, so that the evaporable constituents are removed from it.
  • GB-A-288 148 discloses a process in which, inter alia, the residues of a coal or oil hydrogenation are conveyed through a screw machine and then treated in vacuo.
  • a real forced conveyance is not specified with this method, because the screw essentially serves as a cleaning device and in which problems associated with coking of coke are by no means excluded.
  • pressures of 0.01-0.6 bar preferably 0.02-0.1 bar
  • the pressure drops from 0.6, preferably 0.1 bar to 0.01, preferably 0.02 bar over the length of the screw machine from the entry of the hydrogenation sludge to its exit. This measure reduces the risk of disturbances in the distillation process in the screw machine.
  • the distillation of the hydrogenation residue in the screw machine is carried out in particular at temperatures of 200-400 ° C., preferably 250-350 ° C.
  • the temperature increases from 200 ° C., preferably 250 ° C. to 400 ° C., preferably 350 ° C., over the length of the screw machine from the inlet to the outlet of the hydrogenation residue. This shortens the time during which the hydrogenation residue assumes high temperatures which favor changes and facilitates the further processing of the residue freed from the volatile constituents. Residues up to a final viscosity of approximately 2000 mPas (250 ° C.) can be handled in the distillate removal by the process according to the invention.
  • the gases withdrawn in gaseous form from the screw machine are expediently mixed with the other hydrogenating oils, e.g. B. combines the hot separator leaving gaseous hydrogenation products and together with these further treatment, for. B. subjected to a hydrogenation.
  • the non-evaporated material can be introduced from the screw machine into a cooling or granulating device, where it is solidified.
  • the goods that can be stored and transported in this form can e.g. B. can be used as fuel or as a feed of a gasification plant.
  • the unevaporated material is heated in the screw machine after distillation to higher temperatures, preferably 350-600 ° C., and is smelted at this temperature, in particular at atmospheric pressure or at a pressure below it.
  • the screw machine expediently has a smoldering zone in addition to the distillation zone, into which the hydrogenation residue is conveyed through the screws after passing through the former.
  • the sulfuric vapors generated are extracted separately from the oil vapors.
  • the resulting coke can finally z. B. can be used as fuel.
  • the screw machine expediently has a compression zone connected to a direct entry system into a gasification reactor.
  • the present method is suitable for processing all hydrogenation residues which occur in the high pressure hydrogenation processes of heavy or heavy oils, bitumen, tar, oils from oil shale or tar sand and the like, in which the feedstock contains hydrogenation hydrogen and optionally in the presence of a catalyst at elevated pressure and elevated temperature, for example by the so-called Bergius-Pier process.
  • a positive-displacement pump system 5 which also serves as a metering unit, is used as the conveying element for the feed stream.
  • the product used in the vacuum screw machine consists of 0.86 t of oil with a boiling range of 200 - 550 ° C at normal pressure, 0.12 t of residue with a start of boiling of at least 550 ° C at normal pressure and 0.02 t of inorganic constituents.
  • the vacuum screw machine 7 was equipped with a double screw and, in the case of the present example, was divided into an evaporation zone 8 and a smoldering zone 9 over the length of the screw cylinder.
  • the hydrogenation residue used is heated to 350 ° C. at 0.1 bar. 0.75 t of volatile constituents are drawn off via the connection piece 10 and passed into the condensate container 12 via line 11 following cooling which is not shown in the flow diagram.
  • the condensate container is connected to the vacuum line 13 and the condensate is drawn off via line 15.
  • the residue obtained from the evaporation zone 8 contained 0.13 t of oil components with a boiling range of about 450-500 ° C. under normal pressure, 0.10 t of a residue boiling above 550 ° C. under normal pressure and 0.02 t of inorganic components.
  • This residue was heated in the smoldering zone 9 adjoining the evaporation zone 8 from 350 ° C. over the length of the smoldering zone to gradually increase to 600 ° C., the evaporation zone 8 and smoldering zone 9 being separated by a mechanical compression stage 16, thereby compressing the residue he follows.
  • the vacuum screw machine was heated by means of jacket heating by means of superheated steam in the evaporation zone 8 and by means of flue gas in the smoldering zone 9.
  • the heating can also be carried out by means of electrically heated heating jaws or by induction heating or, in the case of jacket heating, by heat transfer oils.
