Definitions
- the invention relates to apparatus for thermal pyrolysis of hydrocarbons in order to obtain lower olefins.
- the invention relates to blade machines.
- Lower olefins - ethylene, propylene and butylenes - are basic petrochemical products and serve as raw materials for the industrial production of plastics, rubbers, fibers and coatings.
- lower olefins are obtained by pyrolysis of a hydrocarbon feedstock - ethane, propane, butane, naphtha or gas oil.
- pyrolysis is carried out in plants consisting of a tube furnace and a quenching device.
- the raw materials vaporized and mixed with water are fed into the reaction tube placed in the radiation chamber of the furnace.
- Pyrolysis gases having a temperature of 750 ... 930 0 C are sent via a transfer pipeline to the quenching device, where, in order to stop the reactions, these gases are quickly cooled, and then sent to the installation, where they are separated into target and by-products.
- Undesirable by-products are hydrogen, methane, and especially carbon, partly carried out with a gas stream in the form of soot, and partly forming coke deposits on the walls of the reaction tubes and downstream apparatuses.
- Dilution of the feedstock with water vapor reduces the partial pressure of hydrocarbons, which leads to a decrease in the rate of secondary reactions and an increase in the yield of target pyrolysis products.
- this method has limitations.
- the steam supply is usually 20 ... 40% by weight of the feedstock, for butane - 25 ... 50%, for naphtha - 45 ... 50%, and for gas oil the steam supply can reach 80. ..100% of the mass of raw materials.
- Another method of increasing the yield of the target pyrolysis products is to reduce the residence time with an appropriate increase in the process temperature, so that the amount of heat required for the pyrolysis of each portion of the feed must be transferred to it in a shorter time.
- the necessary increase in the heat transfer rate can be achieved by reducing the diameter of the reaction tube and increasing the difference in temperature of the wall of the reaction tube and the reaction stream.
- the designs of tubular pyrolysis furnaces improved in this direction until approximately 1985.
- the end point of this development was the steel mill type Kellogg company Millicond, in which the maximum rate of heat transfer to the reaction zone was achieved for industrial tube furnaces. In these furnaces 1, the process is carried out in pipes with a diameter of 28 ... 35 mm ⁇ at an outlet temperature of 900 ... 930 0 C and a residence time of 0.05 ... 0.1 s, while the temperature difference between the wall and the core of the stream reaches 120 ... 31O 0 C.
- a further reduction in the residence time in the tubular pyrolysis furnaces was disadvantageous for the following reason. Due to a significant change in temperature in the boundary layer adjacent to the wall of the reaction tube, the optimal residence time for particles of raw materials moving at different distances from this wall varies significantly, so the pyrolysis of a significant part of the raw material inevitably occurs in a mode far from optimal. Under the operating mode characteristic of Millicond-type furnaces, the loss of the target products due to the temperature difference in the cross section of the flow reaches such a value that further reduction of the residence time becomes inexpedient.
- US Pat. No. 5,300,216 describes an apparatus for the pyrolysis of hydrocarbons in the presence of water vapor in a stationary high-intensity shock wave.
- Water vapor superheated in a tubular furnace to a temperature of about 1000 0 C, is supplied at a pressure of about 27 atm through a supersonic nozzle to a reactor, which includes sequentially located mixing and pyrolysis zones.
- Hydrocarbon feedstock - ethane heated to approximately 627 0 C, is fed through mixers into a supersonic steam stream. The resulting mixture forms a supersonic flow, the temperature of which is below the temperature of the onset of reactions.
- the kinetic energy of a supersonic flow is converted into heat.
- the mixture acquires a subsonic speed and a temperature of about 1000 0 C at a pressure of about 9 at.
- the reacting mixture passes the pyrolysis zone in 0.005 ... 0.05 sec., While its temperature decreases to 863 ° C due to the absorption of heat by pyrolysis reactions.
- the conversion of ethane to ethylene reaches 70%.
- the pyrolysis products enter the quenching device and subsequent heat exchangers, and then to gas separation. In this setup, the temperature difference across the cross section of the reacting stream is negligible, and the temperature histories (temperature change as a function of time) of passage of all particles of the feed through the reactor are the same.
- the temperature difference across the cross section of the reacting stream is negligible, and the temperature history of the passage through the reactor of all particles of the feedstock are the same.
- the difficulties that must be overcome when creating such a machine are so great that such a machine was not manufactured.
- US Pat. No. 7,232,937 describes a blade reactor for hydrocarbon pyrolysis, comprising a housing with inlet and outlet nozzles, in the cavity of which fixed guide vanes and a rotor with rotor blades are placed, so that when the rotor rotates, an annular vortex forms in this strip.
- the heat required for pyrolysis is released directly in the volume of the reacting medium as a result of hydrodynamic braking of the rotor blades. Pyrolysis reactions continue in the transfer tube connecting the reactor to the quenching apparatus.
- all particles of the raw materials in the reactor cavity have almost the same temperature, however, the length of stay in this cavity for individual particles is different.
- the temperature histories of the raw material particles differ in the duration of their stay in the reactor cavity.
- the difference in temperature histories leads to a decrease in the efficiency of the process compared to theoretically possible.
- This reactor has a simple design, however, ensuring its reliability is complicated by the fact that the working blades are washed by a stream whose temperature is equal to the maximum pyrolysis temperature.
- the aim of this invention is to provide a simple and reliable blade reactor for the pyrolysis of hydrocarbons, in which the yield of lower olefins is higher than in tubular pyrolysis furnaces, due to the fact that the temperature history of the passage through this reactor of almost all particles of the feedstock is the same.
- the reactor for the pyrolysis of hydrocarbons is made in the form of a scapula machine, comprising a rotor with working blades forming an axial scapular lattice, and a housing having necks for medium inlet and outlet, containing this rotor and stator vanes.
- a fixed guide toroidal hoop is located in the housing adjacent to the outer ends of the blades.
- the housing covers the periphery of the rotor and the hoop so that a passage is formed whose meridional section is in the form of a ring.
- one or more partitions are installed that define the boundaries of one or more identical working cavities. Directly after each partition in the direction of rotation of the rotor is the inlet neck, and immediately in front of each partition is the outlet neck.
- the stator blades include nozzle blades forming a nozzle lattice and diffuser blades forming a diffuser lattice installed, respectively, upstream and downstream with respect to the rotor lattice. Between the exit of the diffuser lattice and the entrance of the nozzle lattice there is a bezoplatochny space.
- the medium in each working cavity is forced to move from the inlet neck to the outlet neck along a spiral path, while current streams repeatedly successively intersect the nozzle grill, rotor grill, diffuser grill, and bezoplatochny space.
- the gaps between the casing and the guide hoop in this gapless space are sufficient so that the flow rates at all points of this space are small, and therefore the pressure at the outlet of the diffuser grate is almost the same throughout its entire length.
- the medium When passing through the rotor lattice, the medium receives kinetic energy, which is then converted into heat in the diffuser lattice, so that the temperature of the medium at all similar points of the spiral path, including the exits from the nozzle lattice, increases in the direction from the inlet to the outlet.
- Each rotor blade, moving along the nozzle grill, is washed by a stream, the temperature of which gradually rises, and then drops abruptly as the blade passes by the partition and its entry into the next working cavity.
- Temperature the mode of the working blades is determined by the time-average temperature of the washing stream. In the reactor of the invention, this temperature is noticeably lower than the maximum temperature of the reaction medium in the reactor.
- Equalizing the pressure in the bezopasnosty space eliminates the pressure drop across the partition, thereby reducing leakage bypassing this partition and reducing the proportion of particles of raw materials that have temperature histories that differ from the temperature histories of particles in the main stream. As a result, it becomes possible to obtain a higher yield of lower olefins than in tubular pyrolysis furnaces.
- the working blades have a profile of the active turbine blades and face the concave side in the direction of rotation of the rotor, and in each working cavity of the reactor there is a bulkhead separating the group of nozzle blades located immediately after the partition in the direction of rotation of the rotor from the other nozzle blades in this working cavity.
- This bulkhead is installed so that a channel is formed connecting the inlet neck with this selected group of nozzle vanes.
- the geometrical parameters of the nozzle and diffuser gratings change in the circumferential direction so that, when the reactor is operating in the nominal mode, almost the same pressure at the inlet to the rotor lattice is provided over its entire length and almost the same pressure at the exit from the rotor lattice is its extent.
- the necessary changes in the parameters of the nozzle and diffuser gratings can be calculated taking into account the temperature distribution and the thermophysical properties of the reacting medium over the working cavity, or can be selected experimentally. Equalizing the pressure at the inlet to the rotor grill and equalizing the pressure at the outlet of the rotor grill can reduce radial leakage in the gaps between the housing and the surfaces of the rotor disk.
- Reducing radial leaks can further reduce the proportion of particles of raw materials that, while not moving in the main stream, have temperature histories that differ from the temperature histories of particles in the main stream. The result is the ability to achieve a higher yield of lower olefins.
- FIG. 1 is a front view of a reactor with two working cavities.
- FIG. 2 shows a section along line A-A of FIG. one.
- FIG. 3 shows a cylindrical section along line B-B of FIG. one.
- FIG. 4 shows a diagram of a pyrolysis installation in which a reactor is used.
- FIG. 5 is a graph showing the temperature history of a feed particle passing through a reactor in a main stream.
- FIG. Figure 6 shows a graph of the change in the average molecular weight of the medium during its passage through the reactor.
- FIG. 7 shows the shapes of the profiles and channels of the blade grids and velocity triangles in the reactor.
- the blade reactor for the pyrolysis of hydrocarbons includes a rotor consisting of a shaft 1 and a disk 2 with rotor blades 3 that are evenly spaced around the periphery of the rotor 2.
- the rotor blades 3 have a profile of an active supersonic turbine blade, radially directed facing the concave side in the direction of rotation of the rotor and form the axial blade lattice of the rotor.
- the shaft 1 is equipped with a coupling 4 for connecting an engine (not shown) and is installed in the housing 5 in bearings 6 and 7 using seals 8 and 9.
- a fixed guide toroidal hoop 10 having a constant cross section adjoins the outer ends of the blades 3.
- the housing 5 covers the hoop 10 and the rotor disk 2 so that a passage is formed having a constant meridional section. This section has the shape of a ring.
- the hoop 10 is hollow and is attached to the housing 5 with the help of radial pins 11 fixed in the hoop 10 and included in the guide slots 12 made in the housing 5.
- each partition consists of a dividing wall 13, as well as aft 14 and bow 15 tips, which are located upstream and downstream with respect to the rotor grill, respectively.
- the edges of the tips 14 and 15 are made sharp.
- the term “sharp edges” means edges having a negligible thickness compared to the pitch of the rotor grill. Tips 14 and 15 are fixed in rings 16 and 17, respectively.
- the rings 16 and 17 are fixed in the housing 5 with the possibility of regulating them position in the circumferential direction relative to the axis of the rotor.
- stator nozzle blades 20 are located, which have a curved profile, are fixed in the ring 16 with a convex side in the direction of rotation of the rotor and form a nozzle grate.
- Stator diffuser vanes 21 are located downstream * in relation to the rotor sieve, which have a curved supersonic profile, are fixed in the ring] 7 with the convex side in the direction of rotation of the rotor, and form a diffuser grating. Between the exit of the diffuser lattice and the entrance of the nozzle lattice there is a bladeless space 22.
- a bulkhead is installed in each working cavity, consisting of a dividing wall 23 and a tip 24 having a sharp edge.
- This bulkhead separates a group of nozzle blades located immediately after the baffle in the direction of rotation of the rotor from the remaining nozzle blades, so that a channel is formed connecting the inlet neck 18 with this selected group of nozzle blades.
- the tip 24 is fixed in the ring 16.
- the rotor rotates counterclockwise, as shown in FIG. 1. Both working cavities work the same.
- the stream enters the reactor through the inlet neck 18 and then moves along the spiral path along the axis of the cavity inside the hoop 10, repeatedly intersecting the nozzle grill, rotor grill, diffuser grill and bezelopny space 22.
- the flow receives kinetic energy , which is then converted into thermal energy in a diffuser lattice.
- the temperature of the medium at all similar points of the spiral path increases in the direction from the inlet neck
- the gaps between the housing 5 and the guide hoop 10 in the bladeless space 22 are large enough so that the flow rates at all points of this space are small, so that the pressure at the outlet of the diffuser lattice is almost the same throughout its entire length.
- the operating mode of the nozzle blades separated by a bulkhead does not depend on the operating modes of the remaining nozzle blades in this working cavity. Therefore, the nominal gas-dynamic mode of operation of this group of nozzle blades can always be ensured, including when the reactor is put into operation, when unsteady flow regimes still exist in the rest of the working cavity. Thus, reliable start-up of the reactor is ensured.
- the geometrical parameters of the nozzle and diffuser gratings change in the circumferential direction so that, when the reactor is operating in the nominal mode, almost the same pressure is provided at the inlet to the rotor grate throughout its entire length and almost the same pressure at the outlet from the rotor grate throughout its entire length (for more details see . below).
- Equalizing the pressure at the inlet to the rotor grill reduces radial leakage through the gap between the rotor disk 2 and the ring 16.
- Equalizing the pressure at the outlet of the rotor grill reduces radial leakage through the gap between the rotor disk 2 and the ring 17.
