Definitions

  • the present invention comprises the combination of a plurality of inlet cone tubes, the majority of said tubes being loosely slip-fitted into exchanger tubes, together with an inert fluid purge of the space between the exchanger tube sheet and inlet cone tube sheet, the inert fluid being supplied at a higher pressure than the heater efliuent.
  • the inlet cone tube sheet is eliminated by utilizing hexagonal tubes welded to each other. The inert fluid effectively purges the cone area of any hydrocarbon which may enter, and because of the slip-fit of the inlet cone tubes within the transfer line exchanger tubes, the inlet fluid may pass around the outside of the inlet cone tubes and into the exchanger tubes.
  • This invention relates to a novel inlet device for connecting the output of a cracking heater with the inlet of a transfer line heat exchanger, together with a method of operating the same.
  • the reaction products In the production of olefins from normally gaseous hydrocarbon by thermal cracking or in the steam reforming of naphtha and the like, it is necessary that the reaction products be cooled very quickly from the cracking temperature to a temperature below the point where secondary reactions can proceed. Such secondary reactions decrease yield and cause coke formations which decrease the length of time a heater can be kept in service.
  • the heater effluent is passed in a conduit to a heavily insulated inlet cone which is in direct communication with the tube side of a transfer line exchanger (also referred to as a cracked gas cooler), the cone being necessary because of the substantially larger diameter of the exchanger.
  • the insulation which may be internal or external, is provided in an attempt to keep the gas as hot as possible until it actually reaches the eX- changer. It is also possible to cool the efliuent directly by injection of a suitable cooling medium but while this effects the desired cooling very rapidly, it results in a significant loss of recovered high pressure steam. As a result, indirect cooling in a transfer line exchanger is V generally preferred.
  • the inlet cone is the most criti cal zone for coke buildup in the entire heater-transfer line system. This is apparently due to the flow characteristics of the hot gases within the cone. Coke may build up on the walls of the cone and eventually break off, causing blockage of gas flow through a portion of the exchanger. Further, it is difficult to distribute the flow to all of the exchanger tubes equally; tubes with low gas flow tend to foul quickly. Ultimately, the resulting high pressure drop requires that the whole heater-exchanger system be shut down and the cone and tubes cleaned out, even through there may be essentially no coke buildup in the heater itself.
  • High severity pyrolysis requires extremely rapid cool ing and very low pressure drop across the cooler. This is accomplished by providing many parallel tubes of small diameter, but such an arrangement demands that the inlet cone have a large volume. This turns the inlet cone into an adiabatic reactor, the same as a large or long transfer line.
  • the adiabatic reaction is contrary to the principles of short residence time cracking, and reduces the temperature and causes coke formation, increasing pressure drop and shortening run length.
  • the area of the heater outlet tubes is typically about one-half of the area of the exchanger tubes, and with a conventional inlet cone the volume thereof may be as much as one third of the volume of the heater coil. Since discharge from the heater is at maximum temperature, the adiabatic reaction is rapid, with a significant effect on yield and coke formation.
  • Another object of the invention is to provide an improved inlet cone for connecting a heater to a transfer line exchanger.
  • Still another object of the invention is to provide a novel method of transferring cracked gas from a heater to a transfer line exchanger.
  • Yet another object of the invention is to provide means for passing cracked gas from a heater to a transfer line exchanger which effectively prevents coke buildup and which does not involve welding all of the tube extensions onto the exchanger tubes.
  • a still further object of the invention is to pass cracked gas from a heater to a transfer line without coke buildup, without reducing yield and without loss of heat recovery potential.
  • the present invention is based on the combina-tion of inlet cone tubes, the bulk of which "are loosely slip-fitted into the exchanger tubes, together with a steam purge of the space between the exchanger tube sheet and the inlet cone tube sheet, the steam being supplied at a higher pressure than the heater effluent.
  • the inlet cone tube sheet is eliminated by using hexagonal tubes welded to each other. The steam effectively purges the cone area of any hydrocarbons which may enter. Because of the slip-fit of the inlet cone tubes within the transfer line exchanger tubes, the purged steam can pass around the outside of the inlet cone tubes and into the exchanger tubes. Also because of this feature, the tube sheet of the exchanger is not restricted in movement. Lastly, a much smaller quantity of insulation is required by the arrangement of the invention. In some instances, it may be desirable to weld some of the tubes to 3 simplify assembly and stabilize the position of the tubes in the cone.
  • FIGURE 1 is a cross-sectional elevation of a heater outlet, inlet cone and transfer line exchanger in accordance with the present invention.
  • FIGURE 2 is an elevation of the inlet cone tube openings in an alternative embodiment of the invention.
  • the heater outlet is indicated generally at 10, the inlet cone at 12, and the transfer line exchanger at 14.
  • the heater outlet is provided with insulation 16, a protective sleeve 18 and a flange 20 for attachment to inlet cone 12.
  • a suitable gasket 22 seals the joint.
  • Inlet cone 12 comprises a flanged steel shell 24 with some insulation 26 between heater outlet flange 20 and the inlet cone tube sheet 28.
  • This tube sheet 28 which may be either dished, as shown, flat or dished in the reverse direction, supports a plurality of tubes 30, of which only a few are shown for ease of illustration. It will be.
  • inlet cone 12 there are as many tubes 30 as there are tubes in exchanger 14. At at least one point on inlet cone 12 there is an opening 32 with a suitable fitting 34 for con nection to a source 36' of steam. This need not be especially high pressure steam, as long as it is superheated and ata pressure higher than the effluent gas from the heater. Inlet cone 12 may be externally insulated.
  • a second gasket 40 effects a seal between inlet cone 12 and exchanger 14.
  • exchanger 14 comprises a shell 42 with suitable flanges, a tube sheet 44 supported therein and tubes 46 attached to tube sheet 44, but it will be understood that many different exchanger daigns are employed.
  • the ends of tubes 30 extend into tubes 46, there being a loose, fluid-permeable fit therebetween.
  • tubes with hexagonal ends are employed to fabricate tubes 30, as shown in FIG. 2.
  • the tubes are essentially self-supporting, being welded together to form number would be employed.
  • shield 50 need not be fabricated of metal, but may be refractory or a suitable packing material.
  • the significant operating feature is that the steam pressure in area 38 be maintained at a higher level than the pressure of the heater efiluent. While the steam temperature is not considered critical, the steam must be free of entrained water to avoid thermal shock.
  • a connector duct for passing :fluids to the tube side of a heat exchanger that comprises:
