Definitions

  • the invention relates to a high-pressure hot separator for separating a top product from a process of high-pressure hydrogenation of coals, tars, mineral oils, their distillation and extraction products or similar carbon-containing feedstocks such as heavy oils, smoldering oils, extracts of heavy oil sands and the like.
  • Hot separators as they are known, for example, in systems for liquefying coal hydrogenation, consist of pressure-resistant containers which contain inserts cooled by coils in order to facilitate the separation of a liquid phase with a liquid level in the lower part of the container and to prevent that the separated, also solid, particles on the hot separator wall - Coking or containing ash components, despite the high temperatures prevailing in the hot separator, of low volatility.
  • the lower cooled insert is usually designed as a funnel through which the non-volatile components are removed. In practical operation it has been shown that despite the cooling of the lower insert Pipe coils frequently occur as a result of coking problems which cause the separator to run erratically and even to shutdowns (cf. "The catalytic pressure hydrogenation of coal, tars and mineral oils, Springer-Verlag, Berlin / Göttingen / Heidelberg, 1950, page 243 ff.).
  • hot separators for the application area mentioned at the outset for which a pressure range of up to approximately 1,000 bar, preferably 150-500 bar, are suitable, are built in a finally geometrically and constructively fixed container shape in accordance with the requirements for high and very high pressure requirements.
  • a cyclone separator (4) with an inlet pipe (2) for the tangential entry of a gas / vapor phase containing liquid constituents, a cylindrical section (4 a ) and a lower conical section (4 b), a shielding cone (19) arranged in the cylindrical or conical section in the region of the axis, an axially symmetrically arranged central tube (4 c) for removing the gas / vapor phase freed from liquid parts upwards, the central pipe (4 c) extends beyond the area of the inlet connection (2) into the cyclone separator and is connected upwards with the outlet connection of the gas / vapor phase from the high-pressure vessel.
  • DE 34 05 730 A1 is mentioned, in which a separator for flash evaporators of coal hydrogenation plants and a method is described in which the suspension from the pressure hydrogenation is expanded to low pressures in one or more stages before the suspension is fed to the separator.
  • the separator has a cyclonic structure.
  • a high-level separation function in processes and products of the type used or used in the high-pressure hot separator according to the invention is not specified with the prior art mentioned, but is unavoidable because the bottom phase hydrogenation, as a rule, for the production of products, the reformer application specifications achieve, a so-called gas phase hydrogenation is connected immediately after the residue phase to be separated in the hot separator has been discharged.
  • An inadequate separation function would soon be noticeable in a pressure loss in the gas phase hydrogenation taking place at a fixed bed contact, in that unseparated liquid particles entrained in the gas / vapor phase and the solid residues and ash-forming constituents contained therein would precipitate on the fixed bed contact and block it .
  • the cyclone separator (4) installed according to the invention in the interior of the hot separator is a pure flow apparatus and does not have to be designed for high pressure.
  • the cyclone separator (4) can correspond to the present Process conditions and requirements are calculated and optimally designed.
  • An expedient embodiment of the high-pressure hot separator is that the inlet connection of the cyclone separator is equipped with a washing device consisting of a washing nozzle and a feed line for washing liquid. This effectively prevents the formation of solid deposits in the area of the inlet connection of the cyclone separator.
  • the product inlet pipe for the top product from the bottom phase reactor is expediently designed such that it ends in the gas / steam chamber of the pressure vessel above the liquid level formed by the bottom product in the hot separator and is adapted to the shape of the cylindrical wall insert so that the wall insert is essentially tangential flow is directed obliquely downwards.
  • another expedient embodiment provides that the bottom product is drawn off from the conical part of the cyclone separator through a line connected to an expansion vessel connected downstream of the hot separator.
  • the conical part of the cyclone separator can also be closed at the bottom.
  • the majority of the condensed bottom product is still discharged through the bottom outlet connection in the lower cover of the hot separator. Only the amount of liquid separated in the cyclone separator (4) is drawn off from the high-pressure vessel by means of a separate line, for example through the outlet connection for the gas / vapor phase.
  • the high-pressure hot separator is expediently equipped with a level control measurement.
  • This can be carried out as a differential pressure measurement, with hydrogen being bubbled in via two separate lines, the so-called zero line and a line reaching into the bottom of the conical part of the cyclone, and the differential pressure to be measured in the hydrogen feed lines due to the standing height is registered.
  • the hydrogen inlets for the level measurement and the line (20) for the discharge of sump product from the conical part of the cyclone separator are guided, for example, through the special lens seal on the outlet connection of the gas / vapor phase from the high-pressure vessel, as shown in detail in FIG. 4.
  • the vertical cylindrical wall insert (18) of the high-pressure hot separator merges according to an expedient design via the conical part into the sump drain connection (5) in the bottom of the pressure vessel.
  • the cylindrical wall insert will be part of a cooling circuit for the purpose of indirect cooling by means of lines for coolant supply and removal through the upper or also the lower cover of the pressure container, the wall insert being able to be constructed from fin tubes, as are known from steam boiler technology.
  • the wall insert can also consist of normal pipes with welded-in webs.
  • the present high pressure hot separator can be used in the case of particularly wear-intensive mineral components in the top product of the bottom phase hydrogenation, such as. B. aluminum oxide from alumina, as they occur when using oils from tar sands on particularly wear-stressed zones or on the entire inner surface with wear armor, for example made of tungsten carbide or wear-resistant ceramic coatings.
  • FIG. 1 An overall view of a high-pressure separator with installed cyclone separator in a longitudinal section can be seen in FIG. 1.
  • Figure 2 shows a section along the line A-A of Figure 1.
  • FIG. 3 shows an enlarged representation of a cross section through the cyclone separator, from which the position of the washing nozzle in the inlet nozzle in the cyclone separator can be seen.
  • FIG. 4 is a view of the outlet connection leading from the hot separator for the gas / vapor phase in a longitudinal section and in greater detail.
  • the high-pressure hot separator consists of the cylindrical, vertical container casing (11) with flange attachment zones reinforced at the ends, with which the upper cover (12) and the lower cover (13) are firmly screwed.
  • the non-load-bearing wall insert (18) adjoins the thermal insulation of the pressure vessel jacket (11) and is tapered at the lower end.
  • the conical wall insert (18 a) opens at the bottom into the sump drain connection (5).
  • the top product of the bottom phase hydrogenation from the bottom phase reactor enters the high-pressure vessel via the product inlet pipe (1) through the upper lid.
  • the product inlet pipe into the high-pressure vessel is designed in the area of its mouth so that the top product, which also contains liquid and residue components, flows in tangentially and downward from the bottom phase reactor into the pressure vessel jacket (11) at a short distance above the liquid level held by measuring and control devices.
  • the measuring and control devices are supplied with the necessary data by the temperature measuring probe (16) shown here, as well as the level measuring probes (9).
  • the cyclone separator (4) is fastened in the gas / steam chamber of the high-pressure hot separator to the upper cover (12) in the center of the outlet connection of the gas / steam phase from the high-pressure vessel (3).
  • the cyclone separator (4) consists of the usual components, namely inlet connector (2), cylindrical part (4 a), conical part (4 b) and the central tube (4 c), which is attached to the upper end of the cylindrical part (4 a) is and has a connection to the outlet nozzle (3).
  • the central tube (4 c) in the cylindrical part of the cyclone is pulled down so far that its mouth protrudes beyond the inlet area of the inlet nozzle into the cyclone separator, as a result of which there is still a tear or short-circuit mixing between the inlet nozzle (2) Process stream containing liquid components and the "dried" process stream is avoided.
  • the feed pipe (7) for a suitable washing liquid for washing the inlet pipe (2) freely is passed through the outlet nozzle (3) via the washing nozzle (6).
  • the drain on the lower conical part (4 b) of the cyclone separator (4) is designed as an immersion tube (10) immersed in the liquid level of the high-pressure container.
  • FIG. 4 The outlet connection (3) and the measurement and product lines guided through it are shown in greater detail in FIG.
  • the reference symbols in FIG. 4 have the same meaning as in FIGS. 1 to 3.
  • the special lens seal (17) is shown in FIG. 4, through which the feed line (7) and the lines (15) for the level measurements are passed.
  • An outlet pipe (3), not shown here, for the bottom product from the cyclone separator can also be passed through the outlet connection (3), if this is designed closed at its lower conical end.
  • the immersion (10) is shielded from the vacuum prevailing in the cyclone axis.
